Why Latex Paint Peels Off Old Oil Paint<\/strong><\/p>\n

Oil-based paints cure to a hard, slick finish. Latex (water-based) paints cannot properly adhere to this surface without deglossing and a bonding primer. As a result, the latex layer peels in sheets under stress from moisture, cleaning, or expansion\/contraction.<\/p>\n

Steps to Repair & Repaint<\/strong><\/p>\n

Protect surrounding surfaces and inspect the trim.<\/p>\n

Scrape off all loose\/peeling latex paint.<\/p>\n

Feather-sand edges and degloss remaining oil paint (120\u2013220 grit or liquid deglosser).<\/p>\n

Clean thoroughly with a degreaser or TSP substitute and rinse.<\/p>\n

Fill dings with wood filler and caulk gaps where needed.<\/p>\n

Apply a high-adhesion bonding primer over prepared surfaces.<\/p>\n

Lightly scuff-sand and remove dust after primer dries.<\/p>\n

Apply 2 thin coats of water-based urethane enamel (satin or semi-gloss), allowing proper dry and cure times.<\/p>\n","protected":false},"excerpt":{"rendered":"
