In process; car operation, the coating on the bottom of the body is exposed to gravel, sand, salt, moisture. As a result, the mastic and soil are damaged and erased. Bare metal corrodes.
At the automobile plant, PVC plastic of the brand is applied to the lower surface of the body base and spars for noise insulation and protection against corrosion and abrasive wear «plastisol D-11A» 1-1.5 mm thick over epoxy primer.
In case of damage to the protective coating of the bottom without disturbing the soil layer, clean the damaged areas from dirt, degrease with a rag soaked in white spirit and apply BPM-1 mastic 1.5 mm thick with a brush on a dry surface. Dry the coating in natural conditions within a day or at a temperature of 90°C - 30 minutes.
In case of significant damage to the protective coating with damage to the soil layer, clean the damaged areas of the surface from dirt and rust to the metal and apply GF-073 primer to a dry, degreased surface. Apply BPM 1 mastic to the primed areas of the surface with a brush.
If the life of the car does not exceed 1-1.5 years, the overlap of the new layer of mastic over the old one should be minimal. For a longer operation of the car with a given bottom coating, apply the mastic over the entire surface of the bottom and wheel arches.
Clean the paintwork of the body contaminated with mastic with a rag soaked in white spirit.
In the cold season, before use, keep the mastic in a warm room until the temperature rises below 20°C. In case of mastic thickening, dilute it with xylene up to 3%.
Clean the paintwork from pollution with mastic with a rag soaked in white spirit. Dry the mastic at a temperature of 100-110°C for 30 minutes or 18-20°C for at least 24 hours.
