Can you paint over oil-based paint without sanding?

If you have oil-based paint on your walls and want to switch to a water-based paint, you may be wondering if you can skip the sanding process. Sanding is typically recommended to create a rough surface that the new paint can adhere to. However, there are a few alternatives to sanding that you can try.

One option is to use a liquid deglosser or a chemical paint stripper. These products are designed to remove the gloss and smoothness from the surface of the oil-based paint, allowing the new paint to stick better. Simply apply the deglosser or paint stripper according to the manufacturer's instructions, and then wipe it off with a clean cloth.

Another option is to use a bonding primer. Bonding primers are specifically designed to adhere to glossy or difficult-to-paint surfaces, such as oil-based paint. Applying a bonding primer to the walls before painting can help the new paint adhere without the need for sanding.

It's important to note that while these alternatives can help you paint over oil-based paint without sanding, they may not be as effective as sanding in creating a long-lasting finish. Sanding provides the best surface for the new paint to bond to, so if you want the most durable and professional-looking results, it's still recommended to sand the walls before painting.

Before using any of these alternatives, it's a good idea to test them in a small, inconspicuous area to make sure they won't damage the paint or the wall surface. Additionally, always follow the manufacturer's instructions and take proper safety precautions when using chemical products.
