Yes.
You CAN paint over anything with any type of paint.

You might wanna prep/prime it correctly though, if you want it to stay on there.

Its interior, no need to prime. Depends on the finish and color, and if it's pre-primed or not. Should take 2 coats of paint minimum, maybe 3 if its un-primed and you are using a dark color and a semi-gloss with no primer.

Way to go Mr. Paint store owner...you just cost yourself a gallon of primer sale.

I like to prime...and my paint store owner likes me because of it.

It's interior, so no. I should have said, no cheap crap $5 gal of paint though. A good acrylic should stick just fine, but I know how much you guys like Behr and Glidden, so you may need to prime with those

Re: Painting Over Masonite


ok,

NCpaint here's my deal. Years ago I painted an apartment with latex enamel. Asked the paint store employee if I needed to prime? NOpe they said.

I paint it all out and the paint did not sufficiently adhere to the gloss oil substrate. Maybe it would have adhered better given more time but the property management company wasn't having it.

I spent three days with a palm sander and putty knife stripping every inch of trim and then primed it and then painted it again. For free of course.

Wanna know what the paint store employee had to say? "Gee that's weird. It should be adhering. How much primer did you say you needed?"

In my experience, slick surfaces need to be abraded for coatings to adhere.

Re: Painting Over Masonite


Painting smooth Masonite is like expecting paint to stick to Teflon...

It might hold........weakly.

I counsel customers to haul out their fave palm-sander, some 80-grit paper, and get it dulled-off.
After every molecule of dust is removed, get out the BIN primer from Zinsser.
NOW it'll stick...

Agreed, glossy surfaces NEED to be dulled. The store guy should have said that. Masonite.....thats smooth cement board right? Or similar to the hollow cheap six panel doors. I guess i've never seen the shiny stuff. Being that they're risers, so they shouldnt get beaten up too much, a quick sand and paint should be fine. If you are ever in doubt, prime by all means. If you are worried about adhesion, use XIM ( latex or oil ) or BM Fresh Start (latex or oil ) are excellent "bonding" type primers.

Re: Painting Over Masonite


man o man part of me wants to say hire a painter.. the other part says.. if I need help I would want the help. So it is a toss up and the angel wins..

Scuff the surface and use Gripper by Glidden. If you don't have an ICI Paints store around you can pick it up at HD. It is the best primer.. it STICKS to glass < as in hard to scrape off with a razor blade.. off glass.
