What is TSP? I live in Europe and might be able to get it if I know the full chemical name.

I painted over every door in my condo, all were varnished, that's 9 doors on both sides, and 6 that are part of double sliding or bi-fold doors of which I only did the visible side, plus the interior surface of the two doors going outside.

I used a power sander just to scratch the surface, but not to remove all the varnish, then 1 coat of Zinsser's Bullseye 123 Primer, and then 3 coats of semi-gloss paint. I don't know how long ago that was, at least 10 or 12 years ago--and they still look great. There are just a few tiny nicks which I can touch up with leftover paint.

It's the best thing I did to this place, the doors were very dark and made the condo look very dreary. Now they're a creamy white and brighten every room. I left the trim the way it was a medium stain.

I painted over a varnished piece of furniture very successfully by leaving it out in the hot sun. I have the advantage (?) of living in a country with very hot summers so that the sun would bleach out the varnish. After a few days, I painted over it with no problems at all. Hope this helps.

You do not have to strip the cabinets BUT, you do need to sand them well and as Lorelei said, use TSP to clean them. You could also use a liquid sander. Then I would use the best primer there is which is made by Zinser. (not sure if I spelled that right) but any home store has it and will know what you mean. Then paint it after all that is dried.

TSP bought at Lowe's or Home Depot should be used first. Just mix specified amount in water and scrub surface. Do this a few more times to make sure it's gone over well. Make sure you rinse it off well and follow the directions using rubber gloves. When dry, apply Kilz primer which comes in a few choices. You will need to apply extra coats before you can paint. This will cover up the wood nicely. We used this process on old panel walls before painting over it and had no bleed through.

My sister bought a really nice house but for some reason the kitchen cupboards are made of plywood. In an attempt to make them look good, they've been varnished too many times-and each coat is THICK. She wants me to help paint them-I think they should be stripped first, she doesn't. Does anyone have any experience with painting over varnish? What kind of paint did you use? If you stripped it, did you put on a sealer and then paint?

Also, there is one cabinet that is laminated-how does one paint over that? Please help!!

The very best way is to remove the doors and sand the varnish off. Then use a good primer, and paint the colour you want. The sanding removes the varnish that if left on could cause your paint job to peel and look nasty; the primer creates a paintable barrier-the paint goes on and stays on, but you don't have the paint soaking into the wood and causing you to need more than three coats to get good coverage.

Another, quicker way to paint a varnished surface, is to 'rough' the surface of the varnish with either a commercial product like TSP (labelled as a cleaner), or a homemade rougher like vinegar and water. Apply wearing protective gloves, and use a nylon scrubber pad.

Roughing the surface should break the chemical bond the varnish has with the wood, and makes it easier to paint over without having to worry about the new paint peeling. It doesn't always work, though, so the best thing to do really is to sand the varnish off and start with bare wood.

Painting Over Varnished Trim

I have brown, I think varnished (it has a shiny coat on it, I assume it's varnish), trim in my bathroom. I want to paint it white and was hoping I wouldn't have to do any sanding before hand. Can I add Kilz or some type of primer to the area before I paint and avoid sanding?

Any finish should be prepared before painting. Find some "liquid sandpaper" at your paint store, and follow the instructions exactly. 'Paso' is the best I've ever used, but it can be hard to find. Only one store in our city carries it. I haven't looked online.
