How to glue wood - advice from experienced craftsmen. What is the best glue for wood? Principles of selection. Preparing the surface for application Waterproof wood glue

One of the most popular materials in construction and many other manufacturing industries is wood. Therefore, there is often a need to glue wooden parts in order to obtain. For this, an extensive range of different compositions is offered, thanks to which there is no task simpler than gluing wood to wood.

Types of glue

Of all the varieties of glue, differing in their composition and characteristics, it is necessary to choose the one suitable for solving the corresponding problem in order to get the ideal result.

quickly and efficiently glues wood, leaving virtually no traces. But when exposed to water, as well as low and high temperatures, it partially loses its properties.
“Moment” is a universal waterproof adhesive for gluing wood and more. It is also effective for gluing other materials to wood. Provides instant grip.
for wood does not lose its properties under the influence of high temperatures, does not dry out or crumble. Therefore, it is most often used in carpentry.
characterized by increased adhesion when gluing hard wood. Full adhesion is achieved 20 hours after application. Not afraid of moisture, resistant to high temperatures and prolonged loads.
Casein glue has the same characteristics as polyurethane glue. The disadvantage is its ability to change the color of the glued wood.
Suitable for all types of wood, dries completely after 24 hours and leaves no marks.

Which composition to choose

When deciding how to glue wood to wood, it is worth considering the versatility of using the adhesive composition. Some types are only suitable for working with a certain type of wood, others are capable of gluing absolutely different breeds tree.

Has great value and what specific goals need to be achieved, for example, gluing broken wooden objects or performing facade works. The composition of the glue and its quality play an important role.

Household recipes

There are many recipes on how to make high-quality wood glue with your own hands. To do this, you can purchase ready-made casein in powder form or get it at home. Place low-fat milk in a warm place to sour. When it has fermented, filter it with gauze and wash the remaining casein in water and boil to remove fat. Then spread it on paper, dry it thoroughly and mix with borax (1 part borax to 10 parts casein) until the consistency of dough. Dilute the resulting mass with water (2 parts) and use the resulting glue immediately, since it hardens after 2 hours.

General gluing rules

There are rules for gluing wooden parts that must be followed regardless of which adhesive composition is chosen.

First you need to thoroughly clean the surface. This can be done using sandpaper or a file. After this, dry the parts and apply a thin layer of adhesive using a brush and rub in lightly. All surfaces intended for connection are lubricated with glue, then they are pressed tightly against each other using a press or other method until the composition is completely cured.

When working with any glue, mandatory precautions are required, since even the most harmless composition can sometimes cause a severe allergic reaction. Therefore, gluing wood must be done with rubber gloves. If glue does get on the skin, you need to carefully wipe it off and thoroughly wash the affected area with soap. If the composition gets into your eyes, rinse them immediately with running water.

If you carefully understand how to glue wood to wood, and strictly follow the instructions for using the adhesive composition, then the place where the parts are joined can turn out to be much stronger than the wood itself.

When carrying out renovation work in a house, you often have to deal with the need to glue parts or structures made of wood. You can, of course, combine them and mechanically using screws, self-tapping screws, overlays. But it is adhesive joints, being practically invisible, that make it possible to preserve the beauty of wood and products made from it. Sometimes you need to glue wooden parts to structures made of other materials.

For each individual case, it is necessary to select an adhesive that will reliably connect the parts and will serve for a long time.

Until the beginning of the 20th century, glues of plant and animal origin were mainly used for gluing wood. The emergence of the plywood industry led to the development of synthetic glues. Currently, the range of such adhesives is very wide, as is the scope of their application.

All wood adhesives can be divided according to several criteria:

by origin;
by composition;
by water resistance;
by appearance;
by method of receipt;
in relation to heat;
by type of solvent.

Based on their origin, adhesives are divided into the following types:

plant origin - nitrocellulose, dextrin, starch;
animal origin - fish, bone, flesh, casein, albumin;
synthetic adhesives;
mineral adhesives – cement, silicate, bitumen.

Based on their composition, all adhesives are divided into single- and multi-component.

By water resistance:

low degree of water resistance - for use in enclosed spaces;
medium water resistance - can be used in outdoor structures protected from direct exposure to the atmosphere;
high water resistance - serve for a long time in external atmosphere conditions.

Based on their appearance, adhesives are divided into granular, powder, paste, film, and liquid. By production method (only synthetic adhesives are divided): · polymerization adhesives; polycondensation

In relation to heat, adhesives are also divided into 2 types:

thermoplastic - when heated they melt and remain in a liquid state, and when cooled they harden again;
thermosetting - when heated, they first melt and then finally harden.

By type of solvent:

with organic solvents;
alcohol- and water-soluble.

Currently, adhesives of natural origin have largely given way to synthetic products, which are characterized by low cost, wide availability of non-food raw materials, the ability to regulate the properties of the adhesive mixture, low glue consumption and high curing speed.

But in cases where wooden products and structures are subject to high demands In terms of environmental friendliness, there is simply no alternative to natural adhesives.

Modern adhesives have many requirements, some of which may contradict each other.

Operational requirements:

the glue must connect well and reliably hold the glued parts;
adhesive joints must have acceptable water resistance and weather resistance;
the adhesive seam must be durable.

The economic requirements are as follows:

the cost of raw materials for the production of glue should be low;
the glue must have low consumption;
The glue production process should be as simple as possible.

Technological requirements:

optimal glue viscosity after preparation;
sufficiently long viability of the composition after the introduction of the hardener;
high curing speed;
long term glue storage.

Environmental requirements: low corrosion hazard of the glue, non-toxicity of the components included in its composition. Special requirements: oil and petrol resistance of the glue, transparency of the adhesive seam and some other specific requirements.

The most common types of wood adhesives

Some types of adhesives are used exclusively for needs industrial production wood products. Therefore, we will consider only those compositions that are most often used in everyday life for repairing furniture or other wood products.

Popular adhesives:

Wood glue is made from animal skins and bones. In former times, this glue was widely used in the production of furniture and in wood processing plants. Nowadays it is rarely used both in industry and in everyday life. Wood glue is usually sold in the form of granules that need to be dissolved in water when heated. You can also find a jelly-like mass on sale, which you simply need to dilute with water to the desired consistency.
Syndeticone glue - prepared on the basis of a composition identical to wood glue, but powdered sugar is added to it and slaked lime. Provides high strength adhesive joints, resistant to moisture and aggressive chemicals. The downside is the cooking time - the dry mass must be kept in water for at least 24 hours.
Glue paste - also prepared on the basis of wood glue by introducing crushed wood ash or chalk. It is used not only for gluing, but also for priming and puttying wooden parts. It also holds stone, glass, and metal together well.
Compositions based on animal fats. They are used when there are high requirements for glue safety. The most popular among these glues is casein - it reliably holds together wooden, paper, fabric and leather surfaces. Casein glue is sold in powder form, which must be mixed with water and brought to the consistency of sour cream. 5 minutes after applying the glue, it dries almost completely and holds the parts together. Then the surfaces to be glued need to be pressed even more tightly against each other. The disadvantage of glue is that it stains the parts, so you need to apply it as carefully as possible.
PVA glue is inexpensive and well known. Contains no glue toxic substances, therefore it is widely used for the needs home renovation. It is also good because PVA can be stored for a very long time in a well-closed container. The glue hardens as moisture is absorbed into the surface and evaporates. The glue is not very water resistant. Therefore, in conditions high humidity It is better to use thick yellow PVA, which lends itself well to sanding.

Resorcinol glue. It is used for gluing elements located outdoors, as it has excellent weather resistance. The glue is two-component - formaldehyde resin and hardener. The components can be sold both in powder and liquid form. The glue is able to set quickly at temperatures above +15 degrees. After curing, it forms dark brown joints, so it is not recommended for gluing light wood.
Urea-formaldehyde glue. It is most often sold in powder form, which must be mixed with water. Sometimes glue is sold complete with a hardener. Then one part is treated with glue, and a hardener is applied to the second. Regular composition applied to both elements to be glued, while it perfectly fills the gaps and hardens very quickly. Additionally, the parts can be compressed, this will speed up setting. The glue is toxic. Therefore, you need to work with gloves, goggles and a respirator, and the room must have good ventilation.
Epoxy adhesive is two-component. This composition is almost universal, forms a strong connection between parts, is resistant to water, fuels and lubricants and even some aggressive substances. Dries after 24 hours. The disadvantages include the need to protect the skin when working with glue, as well as its increased consumption.
BF adhesives - for wood, compositions BF-2 and BF-4 are used: BF-2 is used for interior work, and BF-4 for exterior work. The glue must be applied in 2 layers, the interval between applications is 15 minutes. The glue dries under normal conditions within 1 hour. Both compositions have good moisture resistance, and BF-4 can also be used at low temperatures.
Polyurethane adhesive is quite expensive compared to other types of adhesives, but it is of high quality. The adhesive joint is able to withstand high dynamic loads and is not susceptible to changes in temperature, high humidity, and ultraviolet radiation. This glue should be used for products intended for use in adverse conditions.

Heat resistant adhesive. Sold in the form of rods, when applied they require the use of a special “gun”. Most often used for sealing cracks in wooden structures and fastening small parts. Such adhesive joints are resistant to high temperatures.

How to choose the right glue

In order to receive good result, you need to purchase a composition that best suits your tasks.

When choosing, you need to focus on the following considerations:

The opinion of a person who has extensive experience in such work.
Scope of work and its specifics (type of parts to be glued, location and conditions of their further operation). For large volumes, it would be more appropriate to use powder adhesives, as they are inexpensive.
Choose the composition that best suits your needs physical and chemical properties features of wooden products or structures.
Study the adhesive specifications on the label and become familiar with how to use it.
Give preference to glue from a well-known manufacturer, intended specifically for wood, rather than a universal composition. Among the most popular modern adhesives are brands such as Kleiberit, Casco, Titebond, and Moment-Stolyar.

The water resistance class of the adhesive is indicated by the letter D and the numbers behind it:

2 – the water resistance of the composition is low;
3 – sufficient;
4 – high.

The higher the degree of moisture resistance, the more expensive the glue.

Therefore, you should not purchase a composition marked D4 for products used under normal conditions.

Before carrying out work, the wood must be prepared:

It is necessary to select parts that are similar in texture and color, and to reject elements with cracks, damage, or protruding knots.
The parts need to be cleaned and treated so that the pores of the wood are exposed and the adhesive can penetrate deeply into the wood.
The humidity of the parts to be glued should be no higher than 12-18%.

Gluing process:

Most often, the adhesive composition is applied evenly to both workpieces. The thickness of the layer depends on the type of glue and its consistency.
According to the instructions included with the composition, you may need to let the elements sit for a while. This way the glue will penetrate deeper, the moisture will evaporate, and the adhesive substances contained in the glue will be concentrated. All this time, drafts and dust should be avoided on surfaces lubricated with the composition.
Then the parts are connected. They should be pressed tightly against each other. In this case, part of the glue comes out in the form of a roller.
Excess glue must be removed immediately with a damp cloth, spatula or scraper. If this is not done, the roller will harden and ruin the appearance of the structure.
The parts to be glued need to be kept under pressure for some time, using a vice or other equipment.

If the technology is followed, the connection is strong and reliable.

PVA adhesives vary in properties. Some are waterproof and quick drying.

Moisture resistant

A waterproof solution for gluing wood can be prepared from slaked lime and freshly curd cottage cheese. The components are mixed in certain proportions to a working consistency.

How to prepare the mixture

To prepare the working material, take ready-made grain, dry powders, tiles, granules. They are carefully crushed and diluted warm water according to the instructions. Wait for the active components to swell. Then they use it. Store in a hermetically sealed container. All formulations, except casein, retain adhesive properties for several days.

The cooking method is described in the instructions on the package.. U different manufacturers mixtures may differ in composition. Consistency matters. The description of the specific glue indicates the required amount of water. It is designed to produce a mixture of a certain viscosity. If a more liquid material is needed for work, the liquid is added in small portions, and the paste is thoroughly mixed each time.

Before gluing the surfaces to each other, they are cleaned and degreased. Then a thin layer of solution is applied to one of the parts and the surfaces are pressed. To increase the effect, a weight is placed on top; it prevents the workpieces from moving apart. Gluing occurs in 2–3 hours, drying in 2–3 days. The exact period and conditions are specified in the technical characteristics of each composition.

Modern synthetic based adhesives

Ready-made industrial adhesives are often used: Titebond, Moment, Titan.

Titebond (from 200 rub., 0.296 l.)

Glue for Titebond wood American company Franklin International is used in the production of plywood furniture, floor coverings made of wood, in finishing works with wooden products. The composition includes synthetic and natural polymers without solvents. This allows you to get excellent adhesion of surfaces without damaging them.

Titebond II glue Premium carpentry- high quality replacement traditional compositions for gluing wood and paper. It is used in the production of door and window blocks, frames, and furniture assembly. This is a composition with high level moisture resistance, can be used for outdoor work, assembling external door and window fillings, attaching decorations to a wooden facade.

The bonding strength reaches the strength of wood. The connection remains intact for many years.

Moment (from 300 rub.)

Wood glue “Moment Super PVA D3” produced by Henkel has a Soviet analogue - DF51/15V. This is a good waterproof adhesive composition used for gluing paper, cardboard, plywood, and other materials of wood origin.

Waterproof PVA is added as a plasticizing agent to concrete solutions to increase the ductility and water resistance of the working mass, the finished stone. Connection with cement mortar increases adhesion to the surface covered with screed or tiles.

The letter D in the name indicates the degree of resistance of the material to water, 3 is a sufficient level. 4 - higher class, used for special work, expensive.

Titan (from RUB 200 for 500 ml)

Titan glue is universal and reliably glues:

plastics,
glass,
paper,
tree.

It is often used to make various wooden products.

"Titanium Universal" is a quick-drying adhesive suitable for working with wooden surfaces. It quickly gains strength, reliably connects surfaces without damaging them, and becomes transparent.

Adhesive mastic is suitable for finishing works, gluing wooden beams, boards, sockets.

Liquid nails are also compatible with wood and can be used for finishing and decorative elements.

Selection rules

Necessary:

Take into account the volume and specifics of the work. When processing large quantities of wood, it is better to give preference to powder semi-finished products due to their low price.
Pay attention to the characteristics, select a solution based on physical properties.
Find a glue that has a suitable consistency.
Carefully read the information on the label and read reviews about the product.

From this article you will learn:

Very often, during repairs, repairing furniture or making any objects, you have to resort to using a variety of adhesives. Today there is a large selection of them for wood products: from products that have long earned the trust of consumers to innovative compositions created using modern technologies. The adhesive composition for wood can be used for various purposes, for example, for fixing or combining different structures, and thanks to it, safe, insulated joints are formed that are not afraid of moisture. In order not to make a mistake when choosing an adhesive, you need to know exactly the purpose of its use. Next, we will tell you in detail about waterproof wood glue.

What is waterproof wood glue?

Waterproof wood glue can be used for both exterior and interior use. The difference is that in the first case, the wood glue must be both waterproof and frost-resistant, because in our country we cannot do without cold resistance.

If the composition does not meet these requirements, then it can only be used for work in rooms where the temperature is always above zero.

Any waterproof glue has increased hydrophobic properties and holds objects more firmly. These characteristics are important if you are tiling a room in which, for example, water containers are installed or there is simply always high humidity.

If your waterproof wood glue does not react to low temperatures, it is perfect for fixing external elements and for indoor work. Due to the frost resistance and heat resistance of these compositions, you can always decorate open structures that may be subject to freezing and flooding from time to time.

Waterproof adhesives have high adhesion and are therefore suitable for any surface. So, there is a waterproof adhesive for attaching slabs of natural stone, ceramics, ceramic granite products. As you already understand, such adhesives have a wide range of applications, since, in addition to the above, they cope with wood, ceramics, leather, vinyl, glass, plastic, cardboard in various combinations.

DIY waterproof wood glue

There are several ways to prepare wood glue at home, but they are all based on the general principle of soaking and cooking in water.

To make waterproof wood glue, we will need:

granules yellow or solid glue sheets (the quality of the finished composition depends on how light the material is);
boiled water;
tile;
glue for cooking.

Recipe for making waterproof glue:

Option #1:

Wrap the glue tiles in cloth, then break them with a hammer.
Fill the resulting crushed material with cold water, be sure to boiled water so that it completely hides the dry glue. After 4-12 hours you will get a gelatinous mass.
Place the resulting mixture in a water bath and cook for about 15 minutes at a temperature of +60...+80 °C. Don't forget to stir constantly. As a result, all lumps should dissolve, that is, the glue will become homogeneous and liquid.
To make it more convenient to cook the composition, we recommend using a special glue bottle made of two vessels. The larger one is for water and the smaller one is for glue. A small container is placed in a large one, they are placed on the fire together and the mixture is boiled.
You can add hot water during cooking to obtain the required consistency. Remember that tenon or end joints require a thicker adhesive than when working with plywood and other flat materials.
The readiness of waterproof wood glue is indicated by a film that appears on the surface. The resulting composition should flow from the stick in a stream, and not drip.

The glue gun is capable of maintaining the glue temperature at +30...+70 °C for one and a half to two hours without additional heating - this is very important, since wood glue is used only in a warm state. As it cools, it loses its properties, after which it may become moldy or begin to rot.

Option #2:

Mix glue and water in equal proportions.
Boil the mixture, then grind the resulting mass.
Place the mixture on a plate and cut into pieces.
Before starting repair work, dissolve the resulting workpiece in a mixture of water and vodka and boil.
There is another option: during the preparation of the composition, add table vinegar to the water and glue, and when the powder is completely dissolved, pour in vodka.

To achieve new properties, various components are introduced into waterproof wood glue. So, if you mix dry powder with linseed oil or drying oil, it will be possible to increase the resistance of the adhesive joint to moisture. If it is necessary to glue leather elements, add glycerin.

Remember that when room temperature the glue retains the required consistency for up to two hours, after which it gradually thickens. Although this is not scary - the composition can be heated. However, we advise you to prepare exactly the amount of wood glue that you will need, this will greatly simplify your work.

How to choose ready-made waterproof wood glue

Modern manufacturers offer large selection adhesive compositions with various properties: water resistance, heat resistance, slow/fast hardening, long shelf life from the moment of preparation, etc. There are also adhesives that produce such a durable adhesive layer that it turns out to be stronger than wood. Let's take a closer look at the most popular types of adhesives.

Animal glues are a traditional favorite of carpenters and have long been used in the woodworking craft. As the name suggests, such compositions are made from animal skins and bones.
Hot melt adhesives look like cylindrical rods designed for use in special glue guns. Such compositions are indispensable when working with templates and models, because they require no more than a few seconds to harden.
PVA is a polyvinyl acetate emulsion that hardens when dried or penetrates deep into the wood. Positive features This glue is non-toxic, unlimited shelf life, moisture resistance and transparency after drying. Furniture manufacturers value PVA, which is why they often use it in production.
Urea-formaldehyde adhesives are also waterproof compounds. They fill cavities well and harden as a result of leakage chemical reaction. The glue is sold in powder form, which must be mixed with water and applied to the required areas. Another subtype of such adhesives is two-component compositions that use a liquid hardener. Then, when gluing, one surface is coated with a hardener, and the second with glue combined with water.
Contact types of glue form a thin seam between the parts. First, such a composition grabs two surfaces, after which it quickly connects them to each other. This variety is convenient for gluing melamine coating onto table tops, while other types are used for working with veneer. The only negative is the unpleasant smell.
Epoxy adhesives consist of a pair of components: a resin and a hardener, which must be mixed in a specific ratio. After the mixture hardens, durable, insoluble transparent joints are obtained. Such compositions can be classified as waterproof wood adhesives, so they are chosen if the product to be glued will be constantly exposed to high humidity.

Modern waterproof adhesives woodworking have many advantages and can be used in various areas. Thanks to the extensive range, you can always choose a product of excellent quality that is suitable specifically for your needs. If we compare adhesive compositions, presented on the market today, with those that were sold before, the former have greater resistance to temperature changes, air humidity, harden faster, are more durable - and these are just their main advantages.

In Europe and Russia, the DIN EN 204 standard is used to determine the water resistance of adhesive joints. It assumes the following classification and operating conditions for adhesive joints:

D1 - indoors at temperatures up to +50 °C (short-term increase is acceptable). Glue D1 is intended for wood with a moisture content of up to 15%.
D2 - for use in rooms with short-term exposure to water or condensation, due to which the humidity of the material increases to 18%.
D3 - for use in street conditions with short exposure to water. Adhesives in this category are not afraid of fluctuations in humidity levels.
D4 - for indoor and outdoor use. The adhesive joint is able to cope with the destructive effects of the external environment, but manufacturers recommend covering it with additional protective layer, if the product is intended to be used openly.

The table below will help you choose adhesive for specific tasks:

How to work with waterproof wood glue

Preparation

Before gluing any lumber, make sure the surface is smooth and free of dust, dirt or grease.

There are two ways to do cleanup wooden surface: for the first one you will need sandpaper with grain of different fractions (depending on the state of the surface), and for the second - ordinary glass.

The emery must be wound on a wooden block or, as it is also called, a “cracker” - such homemade instrument It is comfortable to hold in your hand, making grinding of parts easier. However, it is worth understanding that this method is intended for relatively smooth elements. If you need to remove a thicker layer, a piece of glass with a smooth edge will come in handy, because the latter perfectly removes a layer of wood.

If the lumber has been stained with oil, grease or paint, then after scraping it is treated with any solvent. It is worth noting that it is better not to glue a part into which the oil is strongly ingrained, as you will not achieve normal adhesion.

Another rule that is important to consider when using waterproof wood glue, namely PVA: the moisture content of the wood at this moment cannot be more than 12-14%. The fact is that water reduces or even eliminates the adhesion of elements.

Regardless of which waterproof wood glue you choose, pressing the parts after gluing is necessary. However, it is not possible to use a press for any shape of elements, so clamps are used for compression. They can be made of metal or plastic, and their arms are made of a material reminiscent of parachute lines. Their help is often resorted to during the manufacture of frames.

In fact, pressing parts is not such a simple task. After all, wood can be deformed, and ensuring a tight fit may require much more time than all kinds of instructions promise. So, a wooden tabletop must be kept in a compressed state for at least five hours, otherwise the deformed board will destroy the joint.

Bonding

1. Cold gluing of wood.

With this method, the mixture does not heat up. You will need:

glue;
clamp;
vaymas;
special clamps.

Let us immediately clarify that weims are cold pressing equipment designed for gluing parts made of timber, frames, and panels. For cold joints, adhesive compositions based on PVAD are used. Since such glue has water base, it does not need much time to be absorbed into the material, as a result you quickly get reliable connection. This waterproof wood glue hardens in 15-25 minutes, after which the product must be kept under pressure for an hour.

2. Hot gluing of wood.

This technology is best suited for bonding thin sheets. The glue is heated using electricity or steam, after which it hardens after 30-40 seconds.

Presses used for gluing wood are divided into the following types:

according to the location of the shield: inclined, horizontal, vertical;
according to the drive used: electromechanical, manual, hydraulic, pneumatic;
by operating mode: positional and pass-through type;
by type of heating: steam, electric, HDTV, water.

For hot gluing, glue is applied to the parts, they are placed in presses, where the wooden elements spend no more than five minutes. Note that the glue completely hardens outside of the pressing equipment.

To achieve a high-quality, reliable connection of wooden elements, both inexpensive PVA (you can even work with them at home) and professional polyurethane waterproof wood adhesives from well-known brands are quite suitable. With the help of the latter it is possible to achieve a strong and durable connection of parts in industrial scale, also similar compositions make it easier for craftsmen to create furniture and other wooden products.

Not only professional carpenters, but also home craftsmen often have to glue wooden products. In some cases, neither nails nor screws can cope with the task. Then you have to select the appropriate wood glue. Domestic stores offer a wide range of both domestic and foreign formulations. They differ significantly in both price and quality. In order not to make a mistake with your choice, it is important to take into account several nuances.

Criteria for choosing wood glue

When purchasing, you should determine purpose of glue. There are universal products that can connect wooden elements among themselves, as well as with other materials (metal, glass, plastic). This is an excellent choice for hobbyists or furniture makers. But carpenters prefer to use narrowly targeted adhesive mixtures; they work best on wood and its derivatives.

Having decided on the tasks, it is worth take into account the characteristics of the tree. Not all types of wood glues can work with damp or resinous wood. Much depends on the density of the material.

It is important to look a little into the future. If the glued product will be in a dry room, then almost any glue will do the job. But at high humidity or low temperature, the strength of the connection can only be ensured by a narrow range of products.

The strength of a seam is determined in different ways. It's one thing when a part can only support its own weight. Completely different properties are required from glue under constant impact loads.

Environmental friendliness is also an important factor. If the smell can be combated by airing or using ventilation, then contact of glue with food can be dangerous to human health.

Few craftsmen continue to make wood glue according to old recipes. Today, manufacturers offer compositions based on PVA, organic resins and polyurethane. All are suitable for wood, but have limitations for other materials.
