b.Because coats can be applied with no wait time
c.Recoating too soon can trap solvents, cause wrinkling, poor adhesion, or lifting
d.Waiting changes the paint color
Giải thích
Applying the next coat before the previous one has reached its recoat window can trap solvent, wrinkle the surface, or lift the underlying film. The product data sheet lists minimum (and sometimes maximum) recoat times. Respecting these windows ensures proper drying and intercoat adhesion.
