YES you can paint Flat over Semi. Sand the walls lightly with a Pole sander and 150 grit paper, just enough to take the shine off. No need to prime unless you have many patches. You can use finish coat paint to prime patches but prime them at least twice to prevent flashing. Contrary to popular belief, Flat paint does flash too.


Flat paint is not durable washing it will leave the paint on your rag. It will however, hide imperfections on your walls, better than a paint with a sheen to it.Can I use flat paint over semi-gloss paint for interior walls?
No cause you will lose the gloss shine from the first paint interior wall.
Yes, there shouldn't be any problem. If you want to do it the correct way you should scuff sand (rough up the surface slightly with a sanding sponge) before you paint.
For any painting job, preparation is the key! You should roughen the surface of the shiny paint for better adhesion, then wash with TSP (sold in home stores like Home Depot and Lowe's), and allow to dry. If there are many coats of paint on the walls, you can get dings that take off several top layers, so it would be better to actually sand some of the paint down before adding more on top. Priming should help too, as it is hard to get good coverage with flat paint over a more slippery, shiny surface. And it's true, it's hard to clean flat paint! Maybe a slight sheen, like eggshell, would be close enough to the look you want, but still allow you to wash the surface later. Good luck!
Yes. just give it 2 coats and it will be just fine. i've been painting for over 15 yrs, and have painted miles of walls.
wash with TSP first. Remember that a flat paint will show any kind of bumping, touch or marking, and will not wash. Use a satin finish and save the flat for the ceilings.
I have always heard you are not suppose to, but I have done it myself a few times with excellent results. But I have always primed over the semi-gloss first with a flat primer tinted the same color as the flat paint color I am using. (Paint stores will tint your primer for free.) So I don't think it's as awful as professional painters/designers make it out to be. You shouldn't have any problems. Good luck!! Hope this helps.
Yes you can... but keep in mind that if the semi-gloss paint is oil-based, you'll need to use oil paint or use an oil-based primer to be able to adhere latex paint to it.





If the walls are in a high use room, such as the kitchen and the bathroom, you'll want ot wash the walls with TSP first. Make certain you use the liquid kind (as opposed to mixing the powder) because you 1. won't have to rinse after the liquid and 2. the liquid isn't toxic.





If you decide not to prime the walls first and find that your roller is slipping as you paint, you won't have a choice but to prime first.





If you are using a color that is hard to cover with (like red, yellow or blue, you'll want to have the primer tinted first. Keep in mind that primer is lots cheaper to buy than paint so one coat of primer and 2 coats of paint are much better than having to put 3, 4 and sometimes 5 coats of red, blue or yellow...





Happy decorating!
wash them first with TSP, start from the bottom of the walls so that you don't get dirt streaks from the runoff. rinse with hot water, changing the rinse water often. then when dry, prime the walls, with a good primer. then you can put any kind of paint on that you 'd like. good luck and happy painting!
