1.Basic repair
the edges and corners of the matrix are missing and uneven parts shall be repaired and filled with putty.
2.Coating construction
coating construction inspection surface putty should be solid, not powder, peeling and cracking.Putty dry, should be polished smooth, and clean up.
3. Penetrant construction
use the short wool roller to roll the coating evenly. It is normal that surface drying may leave traces of the roller.
4.Primer construction
after the permeant surface dries, apply the primer with the short hair roller. In the process of rolling coating, it is impermeable to the bottom, no flow hanging and no brush lines.
5.Topcoat construction
under the condition that the temperature is not less than 15℃, use the short-hair roller to ensure that the bottom is not permeable, no flow hanging and no brush lines are visible in the process of rolling coating. Do not dilute with water during application. The second application must be carried out after the first coating surface dries, and the second rolling coating cannot be carried out after the complete curing.
