Paint Question

mjk91383

Seeing as I have the whole summer to work on the theater, I've decided that I'm going to repaint her. Its only been eight months since we last painted, but unfortunately, since the walls were concrete block my grandpa thought that it would be best to use an exterior satin paint the first time around. Needless to say, the glare on the walls is a total ****.

Fortunately, my grandparents are out of town for the next week. I've taken it upon myself to repaint the theater. I have already gotten everything moved out or covered up, I've just got to go and pick up the paint tomorrow morning.

Question is, in order to cover up the satin paint with a flat paint of the exact same color, will I have to prime the walls or anything? I've never painted over anything other than some tacky flowered wallpaper in my bedroom, so I'm trying to learn as much as I can.

Any suggestions?

I can't answer your question (maybe someone else on the forums can), but if all else fails, the people at the store where you're buying the paint from might be able to tell you.

It depends on what color the existing paint is, and if the new paint will adhere to the old stuff. If the walls are a lighter color now, and you are going to go darker, you probably won't have to prime it. But if you want to go lighter, you should.
I would try a small spot first, and after 2 coats, see how it looks.
If it looks good, just go ahead and paint without priming it.

Actually you need to be more concerned about mixing latex and oil-based paint. If you put latex on before, use latex again. No need to prime because of the *satin*, which is what you asked, I believe. And if you're doing the same color, no need to prime at all.

Don't try to put oil-based paint over latex.... although you can go the other way around.

False. I've tried painting latex (water based) over oil-based and it does not stick. The latex will peel off.

You can paint oil-base over water base, but not the opposite.

Duh... sorry.. complete brain ****. Thanks, Ron.

Actually, you can paint latex over oil with the proper preparation, depending on how shiny and smooth the oil coat is. Sanding the surface may do it. You can also buy specialty primer specifically to put on oil in order to cover with latex.

The easiest thing is to use the same kind of paint.

Yeah, I figured you just floated a smelly one burdette:)

Sometimes, it's easier just to throw up a coat of primer and be done with it. Sure, you lose half a day doing it, but at least you won't have problems down the road.

Kilz premium works great.

Thanks for all of the help, guys.

I spoke with the guy at the paint store this morning and he told me that I wouldn't have a problem putting the flat paint over the satin finish because both are acrylic latex. Using the same brand of paint helps too, I suppose.

I finished about 1/3 of the room earlier today. If I just had sheetrock instead of concrete block, I could be done with it all.

I also ran some tests with the newly painted wall while the television was on. For once, instead of having a hideous blue wall, I had nothing but solid flat goodness.

A good old flat finish also allows me to take down the cheap black curtains I had up over the glaring wall of shame, and put them to better use by actually covering windows with them.
