Do a thorough visual inspection and prep

Any cracked, flaking or peeling areas need to be lightly sanded or scraped (and then thoroughly rinsed) before applying new primer and paint because the weight of the new coat will pull the old paint loose.

“You’ll just end up wasting your time and money if you don’t tackle that first,” says Tom Lee, Senior VP of Consumer Marketing for Behr. Greasy spots may also need a bit of washing with soap, followed by a rinse with clean water. Otherwise, give the walls a quick wipe-down with a damp cloth so that paint will have a clean, dust-free surface to stick to.
