Elimination of small defects is carried out in the following order. Remove the old paintwork from the damaged area and prepare the surface, as described above, for painting.
Cover the surface cleaned to a metallic sheen with a scratch net, which will ensure maximum adhesion of the putty and the treated surface.
Prepare putty, depending on the maximum depth of damage:
- polyester putty brand «PE-0089» applied if the damage depth does not exceed 2.5 mm. Before use, the mass must be mixed with a hardener (100:2,0) and apply with a spatula on a surface cleaned to a metallic sheen and degreased;
- epoxy type dianova resin «ED-20» applied if the damage depth does not exceed 4 mm;
- epoxy putty brand «EP-0020» applied if the damage depth does not exceed 7 mm. Before use, the mass must be mixed with a hardener (100:8,5), then apply with a spatula on a surface cleaned to a metallic sheen and degreased.
Apply several thin layers of putty until the surface is close to the original shape with a slight protrusion above it.
Allow the putty to harden to the point where it is pressed through with a fingernail.
Proceed to prepare the surface for restoration of the paintwork, as described above.
The highest quality of repair work is obtained with the use of polyester putties.
