Why is following the manufacturer’s recoat times important?

Ensuring the next coat bonds properly to the layer beneath. Recoat times are set by the coating system to match how the base layer dries and develops surface readiness for adhesion. If you recoat within this window, the bottom coat is still receptive to the solvents in the next layer, allowing it to evaporate cleanly and form a strong intercoat bond. If you recoat too soon, solvent from the new layer can attack the still-soft base coat, leading to solvent pop, blisters, or pinholes and a weak bond. If you wait too long, the surface may become too hard or fully cured, reducing adhesion between coats and increasing the risk of defects or lift. Following the manufacturer’s recoat times helps prevent these issues and produces a durable, smooth finish by prioritizing intercoat adhesion and proper solvent management throughout the coating sequence.
