Penni Staff asked 2 years ago

My home was built in the late 60’s and has many coats of paint on the interior walls and base boards. I feel certain that there have been oil based paints and water based paints layered. Since I cannot be positive…..what kind of primer should I use (if any) and what kind of paint? I will also be replacing baseboards. Should I prime them as well?

Thank you for your time.

If your walls and woodwork are in good shape and the current layer is an acrylic or latex paint, then priming isn't necessary as long as you repaint with a good acrylic.

If the same good shape is true but the current layer of paint is an oil base and you want to use an acrylic then priming with an oil base primer is necessary. Acrylic and latex paints have a hard time sticking to oil base paints.

For painting an oil base over oil base, priming isn't necessary. But, a good sanding is necessary to promote adhesion. I like to do the sanding and prime just to be sure.

You will have to use a primer if any repairs are preformed. In this case, use a oil base. Also the new baseboards will also need priming. I like to use oil base primer when ever I can for new wood, but you can use an acrylic primer instead.

The easiest paint to use is an acrylic. It dries quickly and doesn't smell bad. Plus, it is less prone to yellowing than an oil base paint.
