Moisture: If the paint was applied while the walls were still damp, this can cause blistering and pealing. An exhaust fan is needed to help get this moist air out of the bathroom.
Surface prep: It’s very important to get all the grease, grime and dirt build-up off the surfaces before painting. Use a strong cleanser and a scrub brush and go over the surfaces well. If you don’t, the new paint can’t grab on.
De-glossing: A glossy surface doesn’t allow the paint to properly adhere. A light sanding will help give the new paint something to hold on to. If your house was built before 1978 and it hasn’t been painted in a while, please consult a professional. Many paints pre-1978 contain lead, and sanding can release lead dust into the air.
Painting: There are two types of paint: latex and oil base. Installing them in the incorrect order can result in peeling. When oil-based paints dry, they have a durable, slick surface. This is one of the reasons they last for so long. If you don’t break down that surface, latex paint will not adhere to it. After prepping, apply a good even coat of oil-based primer/sealer. This will give you a fresh start and allow both types of paints to adhere.
