How do I paint the interior walls of my trailer?

For your walls, use a primer. For cupboards, if you are looking to repaint - I recently discovered Oil Bond (you can get it here on Amazon https://amzn.to/2wGmiNO) where you rub this first on your cabinets. This helps the paint stick so you DON'T NEED TO SAND!! Also add a bit of Oil Bond to your paint. I would also spend a bit more for specific cabinet paint to ensure a smooth finish. I recently did this on my bathroom vanity and it turned out fantastic! Here are my pics of my project: https://wp.me/pUbK5-yRy

Is it that glossy Formica wall or drywall, no problem, the cabinets, real wood or veneer? Best bet is to take picture of wall and a smaller door off the cabinet and got to Sherwin Williams paint store, the professionals can tell you what to get to make the paint adhere well to paint. I have the wood/veneer cabinets from the 80's and can't sand too much with the veneer, so you might get a liquid primer. I have wall paper that was glued so well, I ripped the paper off the drywall and found out from a professional painter there is now a textured primer that will adhere to wallpaper and then you paint over it. The bottom line, get an experience professional not at the regular box stores. Save you time and money for the best look.

Normally, I would say, go straight for chalk paint. One or two coats on clean surfaces is usually plenty. But in a trailer, you probably have all synthetic surfaces that might have water damage, cooking damage, tearing paper and veneer, and other problems. So sand, clean, stain, prime, paint, Touchup, and dry.

If you want the kitchen or bathroom to look larger, paint the walls and cabinets the same color. If you want the place to look really refreshed, paint all the windowsills and for frames white. To make the cabinets look better, go with a wood stain, even if they are fiberboard, repaint the hardware, and paint the inside of the cabinets a light color. Then, of course, don’t neglect the ceilings, floors, and countertops. Nor the plumbing, wiring hvac , or fixtures. The time and money you put into it should pay off in increased rent, sales, or personal enjoyment.

Very best wishes, Jewell

Cleaning should be first, then prime and paint.

People keep saying prime first but u r better off buying paint that has PRIMER IN IT ALREADY
