{interior paint solutions: blocking}


p_SCN_040_06

Allow the proper drying time per label directions to avoid blocking.

Paint blocking or sticking is a pain. Surfaces get stuck together. Do you have to pull the door with all your might to open it? The culprit: paint blocking. Paint blocking is an adhesion problem that occurs when two freshly painted surfaces stick together when pressed against each other. When separated, the surfaces show paint transfer or peeling. This nuisance commonly happens to doors and windows.

What went wrong?
Blocking is most likely caused by insufficient drying time before pressing the newly painted surfaces of doors and windows together. Lack of adequate ventilation will lengthen drying time, so be patient! Err on the side of caution if you’re using slow drying oil based paints, excessive paint, or recoating a layer. These lead to longer drying times than the ones suggested on the label.

How can I fix it?
For a quick fix, apply talcum powder, wax, or soap on the problem area to temporarily relieve sticking. Sand the surface to remove all loose paint and dull glossy surfaces. Clean the area and allow it to dry. Try again with the paint. Prime and apply a topcoat. Let it dry long enough this time!
