What do I have to do to paint these wood panal

Some paneling does not accept and hold paint well... it just peels off. I would try a test spot some where kind of hidden.. wash with TSP, lightly sand, prime and paint... if the paint peels or flakes off after drying... you will be better off to either remove the paneling and install drywall or go over it with 1/4 in dry wall, bead board sheets, ship lap or some other material..

Clean the paneling and let fully dry. Use a coat or two of primer and A coat or two of paint.

Our paneling is painted with the newer primer/paint products. The painted wood significantly does brighten things up.

We are in a log cabin and the previous HO paneled bedroom walls and sheet-rocked ceiling —it really helps alot!

Wall Liner is the perfect solution for old paneling. Once installed, you can paint the wall liner and you have a flat colored wall like drywall.

ALL paneling will accept paint. Clean and lightly sand the paneling to remove any gloss. Prime with a good stain blocking primer, I like Kilz. Then paint like painting walls. You can fill the groves with drywall patching compound. Let it dry overnight. Next day go over the compound with a damp sponge to smooth it out. Prime and paint.

I did my den 14 years ago. Since I have an open floor plan I was afraid there might be grease on the paneling so I washed the walls down with Mr. Clean, l let the walls dry and using fine sand paper went over the walls. Used paint with primer. They looked great and lasted until we took the paneling down 2 Yes ago. We replaced it with dry wall.it's a lot of work but we'll worth it I went from walnut to pale gray.

You can do it! First, wash the walls with TSP & warm water, fill any holes or cracks, prime with Kilz2 (water based primer) then paint. I always apply several coats of primer for good protection, then apply paint. Because your paneling is dark, the more of an even coat of primer you have, the better the paint will cover. Today's paint comes with primer, but trust me, two coats of primer works well with one coat of paint. Less 'holidays' and less shadows. Best of luck.

TSP? That hasn’t been available where I live in YEARS!!

I wanted my walls to look more like a sheetrock finish so years ago I filled the groves with sheetrock mud then when it dried I went back with a roller that is a textured roller it has plastic loops on it and put sheetrock mud in my paint pan and rolled the mud on and while it was wet I lightly trawled it so it was smooth with small pits in it. It ends up looking like a knock down look that is put on sheetrock. So my cost was the sheetrock mud. No one has a clue it is paneling. The nice thing about the paneling is I can hang pictures anywhereand the white paint made my room look bigger. You can see the results on my website www.blackbearmotel.com
