As far as using your paint inside....it's perfectly fine. Folks don't use flat/matte finish anymore, tho. Even on ceilings they use satin...mostly because it brings out the texture on a skip troweled ceiling. On walls and trim, the satin is able to be wiped...flat, not so much. You'll actually wipe the paint off the surface tryin' to clean it. The reason the moisture shows on satin/semi-gloss walls in bathrooms is because the paint is blocking it from soaking into the sheetrock. Flat paint in a bathroom is NOT a good idea. It's prolly more porous than the sheetrock, itself. It will eventually begin to peel.

Good luck and holler at me if you have any questions and, remember...paint is only as good as the surface you put it on.

thanks, that's great news, at least using it as primer will not go to waste.

the bathroom I painted was over around 6 or 7 coats of other paints so I think I avoided the moisture passing through it issue. because of its dull finish it doesnt show surface moisture or let it drip or run (nobody ever turn on the damn vent in there but me ) so that's why I thought it was great. glad to learn flat paint is not a sealer so I should NOT do that for bathrooms and other wet areas like kitchens and laundry rooms.

can you tell me the best applications for gloss vs semi gloss?

im trying to understand how to choose the best overall finish to use all throughout the house for durability, cleanup, and long lasting?

also, did I make a mistake using flat for the exterior of the house? its all exterior treated T1-11 plywood so should I go over all of it with spraying on a clear sealer and if so what would you suggest?
