Q: Do I have to use glaze with my paint when sponge painting?
Answer. No. You don't have to use glaze with your paint for sponging. I seldom do, but glaze will make the paint more translucent - which is something you may want to get from your sponging if you are doing kind of a wash type of sponging. Otherwise, I don't use glaze with sponge painting.
Q: How do you step down the sheen from a semi gloss to a flat paint when repainting?
Answer: You have to prime. Often the problem with a flat paint over anything other than another flat paint or primer is you will get "mud cracking". Mud cracking is a crazing type of cracking all over the surface of the paint and occurs when painting a brittle paint over a softer paint - much like when you paint a flat over caulk. The primer you use should not be a latex primer but an oil or shellac primer.
Q: Can ceramic tile be painted?
Answer: Yes, but not in a bathroom where it is subject to high humidity constantly. I have painted ceramic back splashes in kitchens and other areas. The professionals will etch the tile with acid, then neutralize the acid, clean the tile, prime it with an epoxy and paint it with a urethane. Even a lengthy procedure as this sometimes does not hold up in a bathroom. If you are wanting to paint ceramic in a mild environment not subject to high humidity on an interior wall (other than in a bathroom) you need to clean the tile thoroughly with Krud Kutter and a scouring pad, then clean them again with something like Dirtex or a no rinse prepaint cleaner. Next, you must prime with a high performance primer. I recommend XIM 400 white ( make sure it is fresh and well shaken). Then you may paint it with an enamel paint or other paint suitable for the situation. Oil enamel with be a harder finish and that would be mine first choice. The keys here are: the ceramic tiles must be absolutely clean before you prime or the adhesion of the primer will be compromised. To be sure you have adhesion you should prime a few of the tiles after the cleaning process and do a tape test to be sure you have proper adhesion before proceeding with the whole job.
Q: I am getting blochiness when painting with satin sheen paint?
Answer: You either have to double coat or "double roll" ( a painter's term see double rolling ). The first coat of a satin sheen paint will soak in to a flat paint and the gloss will be higher on the thicker parts of the roller stipple and flatter on the lower parts of the roller stipple. This is referred to as gloss absorption. Recoating with a second coat will even out the sheen and all will be well.
