Paint Problems

 

Foaming / Cratering

foaming

Foaming/cratering: Excessive bubbling that doesn’t flow out and leaves craters or depressions in the paint film.

Foaming/cratering causes: Using a roller cover with incorrect nap length. Painting too soon after shaking. Rolling paint too fast or excessively. Using old paint. Painting over unprimed porous surfaces. Painting when the temperature is too hot, over 90°F.

Foaming/cratering solutions: Properly prime porous surfaces or new work. Use the proper nap length roller cover or a high quality brush. Avoid excessive rolling or brushing. After shaking, allow bubbles to dissipate before painting. Avoid painting when temperature is above 90ºF.

Primers & interior finishes: Priming is essential for better adhesion, sheen uniformity, mildew control and durability. Select a top quality interior paint in the color and sheen of your choice.
