We glue the suction cup to different surfaces correctly, firmly and reliably (methods of fixation, installation from the street, on the windshield). Ways to restore the functionality of the DVR holder

How to stick a suction cup? It doesn’t matter if it’s new or old, with which you feel sorry to part, the device must be properly and securely fixed. At the present time, in almost any supermarket you can see a variety of different devices or simply decorative devices on suction cups. Before purchasing, few people think about how high quality the suction cup itself is and how long it will last. But when the installation processes come, then we begin to indulge in reflections: will this design withstand the “duties” assigned to it?

In the interior, of course, such things look bright, positive and comfortable, besides, they are quite practical in terms of fastening and dismantling. Basically, small shelves for the kitchen or bathroom are equipped with suction cups: soap dishes, all kinds of holders for hair dryers, combs, toothbrushes, washcloths, hooks, towel rings and other things. As well as various fixtures, which are attached to windows and glass in the form of thermometers, recorders or any other gadgets. The devices are often small and designed to hold a small weight.

How to securely stick the suction cup?

How to securely glue the suction cup "tightly", but without using any kind of "superglue"? The advantages of suction cups are that you do not have to damage the walls, they do not need to be nailed or drilled for them. Suction cups provide convenient installation, ease of adaptation and easy disassembly. The reliability of the holding element is affected by such points as:

the quality of the raw materials from which the suction cup itself is made;
the presence of marriage on the suction element;
total weight pressing on the suction cup;
the structure of the material on which the object with Velcro should be placed.

It often happens that on the concave side of the suction cup there are various defects in the form of bumps, seams, microcracks and other flaws formed during manufacture or transportation. Such moments do not allow Velcro to stick evenly to the surface, so after a while it disappears. If a seam or other protrusion is found, the layering should be immediately carefully removed with a blade or a clerical knife. Cracks and tears are difficult to repair, so it's best to replace the suction cup right away. The structure of the suction cup must also be correct and even.

Another circumstance that does not allow the suction cup to stick tightly is a rough or embossed surface. If the tile is made with patterns or a non-uniform texture, then the fastening element will not be held. Also, glue particles, various putty joints and the joints themselves are not able to hold the suction cup.

Fixation methods

Various fixing methods can help solve many mounting problems. All devices will do their job well and will hold the suction cup if all the above and below conditions are met.

The most common ways to securely fasten are:

the use of a degreaser;
the use of products containing a vaseline base;
lining made of self-adhesive PVC film;
silicone sealant.

Whichever option you use, you must first prepare the surface for high-quality gluing. The action consists in treating the place with any degreaser, it can be a nail polish remover, acetone, a special degreaser, a solvent, white spirit and the like. If not even a single alcohol-containing product was at hand, you can wash the surface with ordinary laundry soap, then rinse thoroughly and wipe the required area dry.

The method with cleaning liquids is suitable for items that are light in weight and size. The main thing in this process is to thoroughly clean and then degrease the tile or tile. The surface should be cleaned of any contaminants in the form of rust, soap smudges, limescale, dust and other dirt. After thorough cleaning, you can degrease your surface, and along with the suction cup. After these procedures, you need to firmly press the suction element to the tile. This usually works and the suction cup stays in the right area. If you need to move decorative stand, you should moisten the surface near the suction cup. On a wet wall, the suction cup will perfectly slide to a more convenient place for you and you don’t even have to peel it off.
The Vaseline method improves the adhesion of Velcro to a smooth surface. This option is suitable even for use in an aquarium with water, where there is also a need to secure an object. In addition, Vaseline is absolutely harmless to fish.
Lining made of self-adhesive PVC film is suitable for medium-heavy interior items. Very often attached to the bathroom decorative elements not only for washcloths or toothbrushes, but also for holding towels, hair dryers and other heavier appliances. Self-adhesive is often included with modern accessories, and if one is not found, then it can be purchased at a stationery or hardware store. You need to take the right size for yourself or with a margin, cut out circles from the film of a suitable size and stick it on the tile. After that you need to remove protective film and attach the detail on the suction cups along the contours of the self-adhesive.
efficient and best method for holding large loads is a silicone sealant. It provides a strong bond between two surfaces and is indispensable in case of an uneven structure. tiles. For better and more accurate gluing, transparent silicone should be used. Before applying the sealant, the tile and the inside of the suction cup must also be cleaned and treated with a degreaser or alcohol cleaner. After that, a generous amount of silicone must be applied to the concave side of the Velcro and pressed very tightly to the selected surface. Don't worry if excess sealant sticks out of the suction cup. Traces of such glue can be immediately wiped off with a cloth. Or, after the sealant has completely dried, it can be easily and simply removed with a clerical knife. For high-quality gluing and drying of silicone, you must wait a day before you start using a hanger, shelf or hook. After the sealant dries, it is able to withstand massive bathrobes, towels, or even heavy appliances. Subsequently, you can not be afraid that the suction cup will fall off and fall along with all the bath accessories. If necessary, the mount can be dismantled quickly with a regular knife.

The ultra-modern vacuum suction cup is now in great demand. Due to very close contact with the surface, a certain vacuum is created, which does not allow the Velcro to just peel off. But these suction cups, no matter how popularized, are able to withstand loads of moderate severity. For heavier items, you will also have to use the above options.

Installation from the street

The installation of elements with suction cups from the side of the street also requires certain fastening technologies. An important role in this matter is played by weather conditions, temperature and humidity. Basically, thermometers are attached to the window from the outside to observe temperature indicators. Also, the density and quality of fastening depends on the type of thermometer: the more expensive it is, the better the suction cups or adhesive base will be there.

In order to properly glue the thermometer on suction cups so that it does not fall off, you should select models that fit your window. For example, for plastic windows there are many modern electronic devices that, if dropped, will bring a lot of frustration due to the loss of such an expensive accessory.

The thermometer you purchased with suction cups or Velcro does not take much time during installation. But how long will it sag before it decides to peel off? The methods below will help you place the thermometer firmly to prevent further chances of falling. Also, when installing a thermometer, it is very important to follow certain rules in order for it to show the correct data.

The mounting location of the thermometer must be chosen so that it is at an equal distance from heat and cold sources. Both the sun's rays and the part of the double-glazed window that can be opened can serve as heat. A favorable place for the device is the north side.
In order for the bonding to be as dense as possible, the device should be installed in warm, dry and not windy weather.
As in previous cases, the glass should be thoroughly rinsed and then treated with a degreaser.
For good vacuum suction cups, a firm hand pressure is enough to make them “tightly” fixed on the surface.
If you are afraid that even with high-quality suction cups, the thermometer can peel off and fall, use PVC film as an additional connection or ordinary double-sided tape.
You can also use a colorless sealant, but in this case it would be better to fix the thermometer on plastic, and not on glass.
Since double-glazed windows are in contact with dust and water from the outside, many people decide to use "superglue". When using this liquid, you should monitor the volume of poured glue. For good bonding This substance needs very little. It is also recommended to use this option on a plastic frame.

When choosing an outdoor thermometer, it is better to give preference to simple and reliable models than "souvenir" products. Such instances often fail in performance and are generally unreliable. Of course, if there is a storm with a hurricane wind outside, then the thermometer may be held only by metal fasteners in the form of self-tapping screws. But for all the others weather conditions suction cups with additional fixation will easily cope with the task.

Attach to windshield

You can mount a DVR, navigator, telephone, radar detector or other gadgets necessary for the driver on the windshield using suction cups. Mounts for gadgets are usually glued to several small or to one large and massive suction cup. But, as practice has shown, any suction cups, even with levers to increase the vacuum, tend to fall and cause great inconvenience to a person who is driving, and even in motion.

There are only two varieties of such suction cups: rubber and silicone, and it is very difficult to judge which is better, because it all depends on the manufacturer and product quality. The reasons why the suction cup can peel off, we discussed at the very beginning of the article, these sources of fall are the same for both home conditions and for a car. Now we will analyze in detail the methods of reliable fastening.

Wetting. But many wet the concave part of the suction cup with water, alcohol or even saliva, which is not entirely correct. Humidification for greater grip is, of course, good, but in the cold such a liquid will freeze, and in the heat it will simply evaporate. Therefore, you need a consistency that will not harden, freeze or evaporate. Motor oil is ideal for this purpose. Literally a drop of this oil should be applied to the finger, and then rubbed with suction cups and glued to the glass of the car.
Additional lining. This technique is suitable for massive suction cups with a lever. Often this lever makes a thorough turn before it begins to create a vacuum, and only begins to work at the end of the clamp. It turns out that the main part works in vain. It is this moment that should be reduced and an additional lining should be made. An ordinary car chamber is suitable for laying, in which you need to cut a circle with a radius equal to the suction cup. Then in the resulting rubber mug you should cut out the middle so that there remains, as it were, one rim, which will need to be inserted between the suction cup and the plastic recorder holder itself. For a more detailed and visual study, you can see the corresponding photo with an arrow pointing to the gasket. It would also be useful to lubricate such a design with oil. When you start gluing the improved suction cup, you will immediately feel how much pressure has increased inside.
For automotive glass with silk-screen printing, airbrushing or other “pimples”, many motorists come up with a lot of interesting ways to hang the necessary devices. For example, some use the version with an anti-slip mat, which is attached to the coating with auto-painting double-sided tape. And a gadget with a suction cup is already glued to the mat. Also widely used is the method glass mugs or simple smooth glass from an old flashlight. Again, this design also needs to be glued. Gel-based "superglue" is in demand, with which a piece of glass is attached to the relief part of the windshield.

Self-adhesive or silicone - for the most hopeless cases or in winter. This is the case when your devices refuse to "cooperate" with the options described above. In all methods, of course, it is necessary to follow the basic rules of application and application, which include good temperature conditions and a degreased surface.

Taking into account our advice, you can easily and quickly fix an incredibly beautiful and stylish soap dish with your own hands, outdoor thermometer or other convenient decorative elements. And by applying some examples in practice, you will stop waiting for the moment when this shelf on suction cups will fall!

It is a perfectly justified reluctance to drill the walls in the bathroom or kitchen to attach a shelf, a soap dish, a glass for toothbrushes, hooks and other accessories and fixtures, and using all these devices that have a suction cup can be a problem. secure fixation data of bathroom and kitchen attributes to smooth surface tiles.

Suction cup accessories attach securely to smooth, flat surfaces such as tiles, mirrors, metal or glass

What needs to be done to securely stick the soap dish and other accessories on suction cups, on tiles, glass or mirrors? There are several ways to attach the suction cup so that it sticks firmly to any smooth surface, and does not fall off at the most inopportune moment, with an object fixed on it.

Benefits of attaching items to suction cups

The main area of application for items that have a suction cup for attaching them to a smooth surface of a tile or glass is a bathroom or kitchen. If earlier, almost the only accessory that could be stuck on the wall with a suction cup was a hook, today the list of such items is quite extensive and is constantly updated. On sale you can find the following products with suction cups:

hooks;
soap dishes;
glasses for toothbrushes;
shower head holders;
toilet paper holders;
towel holders;
decor items;
shelves for bathroom accessories and cosmetics.

Most often, suction cups are used in the bathroom.

The growing popularity of products with this type of attachment is due to a number of advantages that the suction cup provides:

a soap dish, hook or any other object can be quickly, within a few seconds, attached to the right place on the ceramic cladding;
so that the fixture is securely held on the tile, it does not require the use of mechanical and electrical tools and drilling of walls for mounting various brackets and clamps;
if necessary, the product can be easily dismantled without leaving any traces and transferred to another place;
small price.

This type of fastening is designed for mounting oversized products and items that are light in weight.

Factors affecting the strength of the attachment of the suction cup to the surface

There are several factors that can affect the quality of a suction cup.

The reliability and strength of the connection between the suction cup and the tile depends on three factors:

From the material from which the surface is made and its condition and quality. The base must be absolutely flat and clean, without chips and potholes, and it is better if the tile has a glossy front side. On matte ceramics, the adhesion of the suction cup to the surface drops significantly, and it is hardly possible to stick anything on relief tiles at all.
From the total weight of the device itself with a suction cup and the weight of the object located on it.
From the quality of the material of the device and the presence of flaws on it. When buying fasteners with a suction cup, you need to pay close attention to the inner working side of the device so that there are no bumps and growths on it that will not allow you to securely glue the device to the tiled surface.

Bumps and growths with inside suction cups, can be cut with a sharp knife or blade.

Mounting methods

Whatever option you choose to attach the suction cup to the tile, before you stick it, you need to prepare the surface of the ceramics. The work consists in degreasing the installation site with any accessible way. This can be either treatment with special compounds such as acetone, or the usual cleaning of tiles with soapy solutions, followed by thorough washing of the surface with water.

in the bathroom, help to maintain order, because this accessory allows you to place each item on the intended for him

There are several ways to attach the suction cup, the most common of them will be provided for consideration:

Degreasing of the bonding area. To obtain a better result, use alcohol or acetone. The method is used to attach devices that have a small total weight together with an object that will subsequently be placed on it: a soap dish, a hook for a small kitchen towel.
Treatment working surface Vaseline suckers. This option allows you to slightly increase the load on the device and use the mount in aquariums.
Use of polyethylene mugs. If this device was not included with the device with a suction cup, then you can easily make it yourself from a special film for lamination, or self-adhesive film one of the sides of which has sticky layer. Having cut circles of the required diameter from the film, they are glued to the tile, and only after that the suction cup is glued.
Bonding with silicone sealant. This method is used when the suction cup mount is heavily loaded or the surface to be bonded is not glossy. After gluing the device with silicone, during the day it needs to be given time to solidify, and only then, the hook or shelf can be subjected to stress.

If necessary, the suction cup, fixed to the silicone sealant, can be cut off with a thin knife or blade and moved to another place.

Thus, competently using the listed gluing methods and following the recommendations for choosing suitable products and surface preparation methods, not entirely reliable and constantly falling off suction cups will serve for a long time and faithfully, fulfilling their duties.

the previous one, since the adhesive tape lasts longer on plastic than on glass, although viewing angles are significantly reduced.

Advantages of fasteners on the dashboard

Convenient dashboard mount.
For many models of DVRs, a torpedo is included in the kit.
Possibility to install the device yourself.
Reliability and durability of fastening.
The ability to take the DVR with you without breaking the fasteners.

Cons of fasteners on the dashboard

Bad review.
It is located in a conspicuous place and can attract the attention of intruders.
Damages the dashboard of a car, wires may be visible.

Dashboard mount - an elementary and cheap type of device mount is suitable for those drivers who are ready to neglect beauty and viewing angles for the sake of convenience and simplicity.

This type of fastener involves embedding the registrar camera in the interior rear-view mirror, but this method of fastening is installed only by specialists and service centers.

Lying on the floor, seat or dashboard? Have there been situations when the suction cup for the DVR fell off right on the road, on the next bump? If yes, then we will tell you how to avoid such surprises.

Why is the suction cup not holding?

The most common reason is cold. In winter, the windshield freezes, the rubber suction cup loses its elasticity and falls off. In such cases, drivers usually warm up the car, substitute the suction cup under the airflow and attach it back. This method, despite its prevalence, rarely leads to long-term results.

But sometimes the suction cup does not hold well in the heat. If the car is often left in direct sunlight in the summer, this leads to numerous unfortunate consequences, one of which is the deformation of the holder mounts.

And it happens that the holder on the suction cup cannot be installed from the very beginning, it simply does not stick to the glass. There are two main reasons: either the glass is dirty or there is a layer of dust on the suction cup, or you got a defective holder.

What to do to keep the suction cups?

Act according to the situation.

There are several ways that work, proven by many drivers, to restore the elasticity of a frozen sucker.

Warm up the car. Wipe the windshield with alcohol and wipe dry. Warm up the suction cup, clean it of dirt and attach it to the glass. For reliability (and if there are improvised means), before returning the holder to its place, treat the suction cup with transparent plumbing sealant or silicone grease.
Budget folk option. Boil the mount in soda solution about 20 minutes. To make a solution of the right consistency, take a teaspoon of baking soda to a glass of water.
Quite a budget and desperate option for the most extreme case. The suction cup can be attached to glass or dashboard with double sided tape. This option is only suitable if you have nothing but adhesive tape at hand, and you need to fix the holder.

Most often, the suction cup is easy to return to its place, simply by warming it up and degreasing the place on the glass. But if the mount is deformed or continues to fall off despite all your efforts, do not suffer and just buy a new suction cup holder. An excellent choice would be

DVRs are increasingly being used in cars: the device allows you to record an accident, and then present the resulting material as evidence. Usually the device is placed on the windshield or dashboard, the suction cup mount is included. But not always the fastener provides reliable installation device that registers events, it's annoying if the gadget flies off on the go, sometimes it crashes and fails. In this article, we will look at what are the solutions to such a problem, the reasons why the holder is so unreliable and weak.

DVR mount

The suction cup bracket allows you to place the DVR in a convenient place for the driver. The device should not obscure the view, but at the same time be located so that the driver can turn the video recording device on and off at any time, see what is displayed on the screen. holders have different design, as well as a different area of the fastener itself for installation, fasteners can be bought separately from the recording device itself.

Suction cups are rubber and silicone, with a lever or the simplest, with a side swivel mechanism, with two rubber / silicone mounts, there are other types. The brackets included in the kit are calculated taking into account the weight of the registrar, but they do not always fulfill their task.

Why doesn't the suction cup hold

Often, the manufacturer is blamed for the weak fixation of the DVR on the glass, indeed, it is difficult to expect super characteristics and high workmanship from a cheap gadget. But is it worth shifting the blame to the manufacturer, there are a lot of reasons why the mount falls off:

the suction cup was not installed according to the instructions;
glass is dirty (oily), dust and greasy stains prevent tight contact;
due to heating (for example, having been under direct sunbeams) the mounting platform is deformed and no vacuum is created;
the holder was attached in cold weather;
the surface for fastening the suction element is uneven;
the bracket is "not native", not designed for the weight of this device.

To understand the issue, you first need to understand how vacuum fasteners work, its principle of holding on a plane.

What holds the DVR bracket

A fastener of the "suction cup" type is held on a plane due to a pressure drop, when a silicone or rubber circle spreads on the surface, a reduced pressure is formed inside it. But the bracket is fixed only in the case when the material is absolutely tight, and no air from outside gets inside the circle. If there is at least a microscopic hole in the gum, there will be no suction effect, such a holder can be safely thrown away. It is possible to fix the suction cup only if it is completely tight, and it is still impossible, pressing it, to immediately release it, in which case it is guaranteed to fall off.

Under what conditions is it difficult to install the holder

The most common reason for a loose DVR bracket is low temperature, basically the sucker falls off in the cold. This happens because rubber or silicone negative temperatures hardens, loses elasticity. Also, the rubber band does not keep in the heat, if you left the car for a while under the rays of the sun, you should not be surprised that upon returning you will find a fallen registrar.

It will be difficult to install the holder on the glass covered with dust, the rubber circle itself should not be dirty either. The suction cup does not adhere very well to uneven glass, for example, if it is silk-screened. Here it is already impossible to level the surface, you need to figure out how to ensure tight contact. Also to be taken into account is Russian market there are a lot of Chinese products, and the fastener may initially be defective.

But if you can’t fix the bracket well in the car right away, you don’t need to despair, there are many different tricks and folk ways, using which you will be able to securely install a portable device on the windshield.

Rules for fixing the holder of the registrar

Before using tricky methods and non-standard tricks, you first need to try to install the suction cup according to all the rules. We install the video recorder by performing the following steps:

wipe the surface on which the device will be mounted with a clean cloth or rag moistened with alcohol or a degreaser, and also degrease (clean) the base of the recorder bracket;
we wait for some time, it is necessary that the treated planes dry;
tightly press the holder to the glass, if it has a lever, press and lower it, hold it for a minute or two, it is necessary that the suction cup “grab” and fix in place;
after mounting the bracket, we check the reliability of the installation - we try to unfasten the holder by hand, but we don’t need to pull very hard.

You need to check by looking at reverse side glass, how the rubber circle was installed: if there are at least microscopic air bubbles, then there is an almost 100% guarantee that the suction cup will not last long. If the bracket does not want to take its place, we try various ways helping the suction cup to be firmly fixed.

Methods to help securely fix the bracket

There are methods that help to secure the suction cup more securely, here are some of them (this is what motorists advise):

warm up the fastener by bringing it to the heater fan, while the car interior should be warmed up;
use double sided tape;
smear the contact surface of the bracket with silicone;
cut a rubber gasket along the diameter of the circle and lay it between the glass and the holder;
to seal, add a little glycerin to the contact plane, you can also use laundry soap, garlic juice.

Not all of the listed methods work 100%, and there are side effects. Scotch tape holds well, but it heats up in the sun and loses its properties. An additional rubber gasket helps in many cases, only you need to take into account that the DVR becomes a little heavier, the load on the bracket increases (it can break), besides, adding rubber is pointless on suction cups without a lever. Garlic juice helps without fail, but not everyone likes the smell that it spreads. A solution of laundry soap gives a good effect, only one point should be taken into account - until the soap is dry, you can move the suction cup on the glass, then everything seizes tightly. Silicone should be smeared with a not too thin layer, evenly, its minus is that it sets well only after a day, if you go by car right away, the fasteners can fall off. Another drawback is that the silicone-lubricated holder moves over the surface.

Doubtful ways of attaching the holder

There are a lot of tips that motorists give, but how useful they all are is a big question. Drivers also advise:

smear the contact surface with engine oil;
use brake fluid as a fixing agent;
moisten the contact with saliva;
put the bracket on superglue;
fix the suction cup on the sealant;
to improve contact, apply Pepsi-Cola.

Motor oil is a good tool for creating a reliable contact, but we must not forget that the quality of the rubber seal of the suction cup, especially from Chinese manufacturers, can be different, the rubber can swell and “float”. Brake fluid and saliva have water base, when moisture dries, the contact reliability deteriorates. Automotive colored sealant does not look aesthetically pleasing, perhaps traces will remain after its application, but transparent silicone sealant will come in handy. Someone fixes the suction cup on superglue, but it looks like a perversion - it’s not a fact that the mount will not fall off, but it will not be easy to scrape off the remaining glue from the glass.

Recorder Bracket Repair

It is not uncommon for the suction cup itself to become unusable: the plastic pin that holds the “hat” breaks. This happens if, when removing the DVR, pull it by the body, without being careful.

One way to fix it is to smear the pin with superglue, only the connection will not last long, sooner or later the “hat” will fall off. The easiest option is to buy a new mount, and you can still try to restore the suction cup, repairs will cost much less than buying. Consider how you can repair the suction cup with a lever:

Thus, you can restore almost any bracket for the DVR, the procedure takes a little time, and you do not need to buy a new holder.
