Cracking/flaking causes - old oil based paint that loses adhesion, flexibility and becomes hard and brittle. Poor surface preparation. Substrate cracking underneath paint film, e.g. plaster. Over thinning or over spreading paint beyond manufacturer's recommendations.
Cracking/flaking solutions - remove all loose paint with a scraper. Sand the surface and feather the edges. Spackle® deep scars caused by cracking/flaking of multiple coats of paint and sand. Remove all sanding dust. Spot prime any bare areas.
Primers and Interior finishes - priming is essential for better adhesion, sheen uniformity, mildew control and durability. Ask your Muralo dealer for the best Muralo interior paint for your project, in the color and sheen of your choice.
