Paint Problems


Paint Incompatibility


Incompatibility: Causing adhesion loss from a top coat of latex over many layers of old alkyd or oil based paint.

Incompatibility causes: Usually caused by painting over 3 or more layers of alkyd or oil based paint with a latex top coat. The old paint has become brittle and will lift off the surface. Inadequate surface preparation. Using a not recommended top coat.

Paint incompatibility solutions: Remove all the loose paint by scraping or wire brush for masonry. Power washing is recommended for large areas. Feather sand edges for smooth appearance and rinse thoroughly with a hose. All bare areas will need spot priming.

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