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" 1–1.2 mm thick over EP-083 epoxy primer.
1. In case of damage to the D-11A plastisol coating without disturbing the soil layer, clean the damaged areas from dirt and apply plastisol to a dry surface with an airless spray or brush.
2. Dry the plastisol at 130°C for 30 minutes. It is allowed to apply anti-noise mastic BPM-1, which can be dried in natural conditions.
3. Before restoring the coating, place the car on a lift, carefully inspect the bottom of the body and identify defects in the coating.
4. Clean the bottom of the body from dirt, remove rust with a spatula, sandpaper or rust converter according to the instructions.
5. Blow the bottom of the body with compressed air.
6. Place the car on a lift in the mastic chamber and remove the wheels.
7. Close the brake drums and discs with protective covers, isolate the driveline, mufflers, cables and other places that cannot be treated with mastic with thick paper and adhesive tape.
8. With a rag soaked in white spirit, degrease the places cleaned to the metal.
9. Apply primer GF-073 to the cleaned places by spraying or brushing and hold for 5–10 minutes.
10. Then apply by spray or by hand (brush or spatula) mastic BPM-1 on defective places with a layer of 1–1.5 mm. Overlapping over the old coating layer should be minimal.
11. 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 xylyl up to 3%.
12. Clean the paintwork from contamination with mastic with a rag soaked in white spirit.
13. Dry the mastic at 100–110°C for 30 minutes or 18–20°C for at least 24 hours.
