Names of automotive upholstery adhesives and rules of use
Regardless of how the driver takes care of the car, the interior trim will wear out over time. In this case, it will be necessary to rewire the materials with which the door, ceiling and other room boards are sheathed. This procedure is carried out using specialized formulations. The choice of adhesive for tightening car interiors largely depends on the type of upholstery material.
Primary requirements
When choosing an adhesive used for interior decoration, it should be borne in mind that such compositions must meet the following requirements:
- nontoxic;
- provide reliable adhesion to the surface;
- evenly distributed over the finishing material;
- does not leave stains.
An important condition is the choice of glue, taking into account the type of finishing material. In particular, the white compound is not recommended for fixing black coatings.
The following materials are used in car interiors:
- Carpet. The most affordable finishing material that wears out quickly.
- Alcantara. An expensive synthetic material with increased durability.
- Leather. Environmentally friendly finishing material with a service life of 10-12 years.
- Eco-leather (artificial leather).With proper care, the service life does not exceed seven years.
- Herd. Relatively inexpensive material that is difficult to work with.
- Velvet. Easy to maintain material with a lifespan of less than four years.
When choosing an adhesive composition, in addition to the above factors, it should be borne in mind that the product must withstand regular temperature changes.
Which glue is right
Some materials (especially carpet) are made with a self-adhesive backing. In this case, you do not need to purchase additional compounds to fix the new skin. If there is no such basis, then you will have to choose the appropriate glue, taking into account the technical characteristics of a particular product. The properties of the composition are determined depending on the contained components.
Based on polychloroprene
This product is based on various resins and metal oxides, thanks to which the polychloroprene-based adhesive provides strong and durable fixation. This composition is applied to both surfaces (on the material and the surface on which it is glued).
Polychloroprene-based adhesives include:
- "Clay-88";
- "Mah";
- "GTA Botterm".
Choosing a glue based on polychloroprene, you should take into account that this product does not tolerate a temperature rise of up to 60 degrees. With this effect, the compound begins to melt, which decreases the degree of fixation, and carcinogenic substances enter the living room.
Despite the above drawback, this composition is very popular among motorists. This is explained by the fact that after gluing the case, the machine can be used after half an hour.
Polyurethane
Polyurethane compounds are considered the most optimal for constricting car interiors. Products of this type belong to the universal group. That is, polyurethane glue can be used to fix different types of materials. This composition hardens for a long time, which allows, if necessary, to eliminate the inconveniences of fixing the skin.
Polyurethane adhesives include:
- “Demoskol”;
- "Moment";
- "Titanium";
- Kaiflex K414.
Employees of service centers recommend motorists, who have never been involved in interior styling, to use only polyurethane-based adhesives.
Other Alternatives
In addition to the above products, there are other variants of automotive interior adhesives on the market. To facilitate future work, it is recommended to purchase formulations with the following characteristics:
- easy to use;
- do not spoil the finishing material and do not flow;
- distributed in a thin layer over the surface;
- do not form lumps;
- smooth the sheathing;
- dry quickly;
- does not penetrate deep into the fabric, being printed on the back.
Spray adhesives are considered the best choice for upholstery. These products correspond exactly to the above specifications.
Execution rules
In addition to the new material, to firm the skin, you will need:
- adhesive composition;
- degreaser (alcohol, acetone, gasoline);
- screwdriver;
- fine grit sandpaper;
- hard sponge;
- roller for leveling the surface;
- masking tape.
It is also recommended to purchase a construction hair dryer, which will speed up the drying of glue, and plugs. The latter, when fired, break and cannot be restored.
Replacing the coating is carried out in several stages.If the ceiling is dragged, they are removed first:
- pens;
- visors;
- ceilings and other decorative elements.
Then the old coating and the foam rubber are dismantled. The surface is then treated with soapy water and a hard sponge. In addition, the ceiling must be degreased with appropriate means. This must be done, because traces of old glue remain on the surface, due to which the new canvas will not be fixed firmly enough. Finally, sand the ceiling.
After preparation, a thin layer of glue 10 centimeters long should be applied to the surface in the center (if necessary, the casing is also treated with the composition). Then the selected material is glued to the ceiling. Further, with a step of 10 centimeters, another layer of adhesive is applied and the coating is fixed.
Following the described procedure, you need to carefully handle niches and bends. In these places, the finishing material often sags, which is why in the future it will be necessary to carry out repeated constriction. When gluing, the coating must be immediately leveled by roller or by hand. To avoid sagging, the material must be stretched.
At the end of the work, the excess coating is cut off. In addition, in the finishing material you need to drill holes for fixing the previously dismantled decorative elements.
If sag is revealed after the work is complete, that area should be reheated with a jobsite hair dryer. Otherwise, a new constriction will be necessary. It's also worth bearing in mind that roof leaks are possible in older cars. Therefore, before starting work, it is necessary to check the tightness of the body and eliminate the identified defects.
Review of popular brands
The market offers a wide range of products used for car interior upholstery. Some of these formulations are very popular.
"Moment"
Moment is a universal adhesive used for fixing various materials. However, this product is toxic and spreads on the surface. In this regard, "Moment" is generally not used to stick trim in the cabin.
"Kaiflex K414"
Another product based on polyurethane."Kaiflex K414" differs from other adhesives in that it provides strong fixation of the finish on the surface and reacts well to temperature changes, retaining its original properties when the interior overheated.
"Titanium"
"Titanium" is rarely used for waist padding. This product dries for a long time and does not tolerate temperature extremes.
"Demoskol"
It is recommended to use "Demoskol" for upholstering the interior of old cars. This composition is characterized by increased resistance to moisture. In addition, "Demoskol" is not affected by temperature extremes.
"Glue-88"
A universal tool for restoring interior upholstery. Glue 88 is used for fixing various materials, including Alcantara and natural leather. This product is highly resistant to humidity and temperature extremes. The disadvantages of the product include the fact that "Glue-88" does not provide strong fixation of the coating to the surface and has a pronounced unpleasant odor.
"GTA Boterm"
GTA Boterm is distinguished by its ability to withstand exposure to high temperatures and humidity. However, working with this range is more difficult than with the previous ones. To gain strength, the glue requires exposure to temperature (treatment with a building hair dryer).
"Mah"
"Mah" is considered the optimal adhesive composition for tightening the upholstery of the car interior. This product exactly meets all requirements for such products.
Additional tips
It is recommended to slide the interior of the car in two people: one person glues the material, the second pulls and smoothes the trim. When working with leather and other finishes, it should be borne in mind that bubbles appear due to errors in the procedure. Due to such sagging, you will have to re-manipulate, pulling on new skin.
