How to choose anti-gravel

Which anti-gravel is better to choose depends on the size of the treated area, adhesion ability and professionalism of the master. With the help of an aerosol, it is good to work with hard-to-reach and small areas. For large areas, guns and films are suitable. If it is planned to paint the treated surfaces, then a high degree of adhesion to paints is important.

A type

An aerosol is suitable for treating surfaces at home. It covers a small area and forms the thinnest film. If you need more coverage, you can use a spray gun, but this will require certain skills. Anti-gravel films are a good solution for protecting or decorating a car, but their installation requires some experience and special tools, so entrust this work to professionals. The least popular composition is packaged in cans, it is applied with a brush and requires the appropriate skills.

Application area

For painting plastic surfaces, textured anti-gravels in cans are suitable. They are relevant in the treatment of the body and arches due to their transparency and lack of influence on aesthetics. If you plan to finish the bottom and thresholds, then you should pay attention to the composition with a bitumen base, but it is not recommended to paint it later.

Colour

For comprehensive protection of body parts, it is better to choose a transparent universal product. It will work with any car, regardless of color. If the task is to treat the sills, underbody and wheel arches, then special products available in gray, white or black will be relevant. If the color matches the car, the mixture can also be used for body surfaces.

The basis

The composition of aerosols and guns can be based on rubber, synthetic resin or polyurethane. They are characterized by a high level of protection of parts from scratches, chips and other damage after being hit by stones, gravel, salt and water. Also, these products have sound insulation properties. Films are made of polyvinyl chloride or polyurethane. If the task is to decorate the car, then it is better to choose the first option - it protects the surface worse, but has a wide range of colors. For good protection, a polyurethane mixture is suitable.

Application method

The most convenient option, which does not require special skills, is application with an aerosol. For large areas, it is best to use a spray gun or brush. If you have certain skills, then the work can be done at home, otherwise it is better to entrust it to professionals. Applying the film requires tools and experience, so it is not recommended to process the vehicle yourself.

Which anti-gravel is better

In many ways, the choice of anti-gravel depends on the setting speed:

• If drying time is not the main criterion, then you can buy anti-gravel spray paint "HB Body 950". Complete hardening of the material occurs in 24 hours.
• For those who appreciate fast drying, it is better to purchase Novol Gravit 600 (40-60 minutes) or Astrohim Antiruster (2 hours).
• For immediate setting, 3M transparent protective film 100 mm x 2.5 m is suitable.
• The optimal setting speed is shown by Dinitrol Drohnex 440/445 (30 minutes), Liqui Moly Steinschlag-Schutz 6106/6110 (2 hours) and HB Body U951 Auto Flex Underbody (20-30 minutes).

A high-quality anti-gravel composition is a guarantee of the integrity of all surfaces of the car for several years. The review presents the most reliable and safe formulations.
