We have paneling in bedroom and living room. Can we paint it ?

Make sure your paneling is solid wood - if not, that’s another issue.

Inspect Paneling

In some instances you may be able to remove the paneling and paint the walls directly. But often paneling was installed with both nails and adhesive, and you could damage your walls if you try to remove the paneling. Also, in some cases the paneling was placed directly on the wall studs with nothing behind it. When you're ready to start painting, dd. Some paneling actually consists of a vinyl print that simulates the look of wood. To check, sand a small area on the wall. Vinyl coatings come off quickly, revealing the pressboard underneath. If your walls have a vinyl or thin veneer finish, you'll need to take extra care when painting them.

Yes and it's going to make a beautiful impact on your home and use a paint with primer in it and crown molding will be an added touch. Here's a few pictures

Old wood paneling ... sure. I've painted my friends house white and it looked amazing. I first cut around the ceiling, baseboards and corners with a brush, and did all the indentations for the faux boards. Then I rolled it out using a foam roller. 2 coats of kitchen and bath semi-gloss paint that we added 1/2c plaster of paris to a gallon to make chalk paint. I first washed the paneling using a car sponge because she used wood heat.

yes

Yes you can paint over paneling. They actually make paint for that exact purpose. I recommend talking to a paint pro at your local home improvement store. He/she will be able to tell you how to prepare for paint, sanding, cleaning, etc. In this case, I think that advice would really help you. Good luck.

I painted over one wall in a bedroom that had vinyl (I think) paneling. The first thing I did was to clean the paneling well. Then I used joint compound or spackling paste to fill in the indentations between the panels. I let that dry, then sanded it down. There were still some indentations so I did a second coat. Again I let it dry then sanded it smooth. It turned out great I used primer and 2 coats ofnsatin finish paint. I would think that chalk paint would really work great, but use a paint of your choice.

yes you can I painted mine and it looks great.
