How do I paint over oil based paint?

Yes, light sand wit a very fine sandpaper, it will take 10 minutes. Then buy a gripper primer Glidden makes a good one, or a stain blocking primer in Oil based. Then you can paint in any Latex that you want.

They don't need to be sanded down to the wood, but they do need to be scuffed up a bit so the primer and paint can stick to them. Think about a skillet with oil, everything slides around in the pain. Use a skillet without oil to fry up something and it sticks to the pan.

I suggest getting some foam based sanding blocks - not fine, not extremely coarse, just medium, and lightly sanding them. Every time you go in the kitchen, sand another side; get the kids to help.

After sanding, wipe them down completely with a damp - not wet - cloth. Spend your money on a good primer - I like Kilz. If you're going to paint with latex paint, get the latex primer. Prime them, lightly sand again and wipe down and then apply your paint. Consider using a sealer after the paint job is done. There is a great water-based sealer I like called Varathane Ultimate Polyurethane Clear Satin. You can order it through Home Depot. Good luck.

Hi Carrie! There are products such as Krud Kutter that will help clean and rough up the surface slightly. Glossy paint prevents good adhesion. Wipe it down really well (I like to use a damp microfiber cloth) after the surface is clean, to remove any residue. Sanding is a little more time consuming but will help smooth a surface. BUT I would scrape off the newer paint, or strip it off (my preference - with Citristrip), or you are going to have an uneven, unstable base for new paint. After the newer stuff is removed, Krud Kutter will help prep the old surface. Then use a good sealer like Kilz. Once the prep is complete, you will have a good base for your latex paint.

no get small sander that has little bag attached ..there is a liquid sand not sure would work good luck

Sounds like this is more than I wanted, thanks for the info.
