1 surface treatment: removal of the substrate surface by sandblasting, loose material, electric wheel, steel wire brush or coarse sand paper, grinding, improve the repairing surface roughness, acetone cleaning agent cleaning, clean and surface.

2 glue: repair agent is composed of A, B double component, use strictly in accordance with the provisions of the proportion will be the main agent A and curing agent B is fully mixed to uniform color, and can be used to run out in a specified period, the excess glue can not be re-used;

Agent 3 will be a good mixture onto the substrate surface treated, apply force should be uniform, repeatedly press, to ensure full contact with the substrate surface, in order to achieve the best results. Need a multilayer coating, need to deal with the original coating surface before painting;

The 4 lower than the temperature 25 ℃ may be appropriate to extend the curing time, when the temperature is below 15 ℃, heating using appropriate heat (infrared, electric and other), but heating can not directly contact the repair site, correct operation is the source from the repair surface above 40cm, 60 ～ 80 ℃ keep 2 ~ 3 hours.
