Plastering is the process of covering uneven or rough surfaces with plaster and is commonly done on walls and ceilings, usually for two purposes. Firstly to provide structural support to the wall or ceiling and then secondly, for decorative purposes to cover up imperfections and provide a smooth surface for renovation.

Can You Plaster Over Paint?

The answer to that question is, to put it simply, yes. Yes, you can plaster over paint, however, there are factors which should be considered first.

Your first step is to assess your wall. If the paint on your wall is in good condition, then a professional will likely be able to start the plastering process straight away. Paint that is in ‘good condition’ won’t have damages or cracks and won’t be peeling either. It is also best if the walls themselves are clean of dirt, and dust.

If however, the paint is not in good condition or the wall has recently been painted it is best to avoid plastering over the paint directly. This is because walls which have paint that is no longer in good condition will either need repairs or a professional may need to strip the paint first.

Hiring a Professional Plasterer vs. DIY

While it might be tempting to DIY plastering over paint, plastering is a complex process best left to a professional. The plastering process itself is highly technical. During your renovations, a plasterer will use their skills and expertise to ensure no detail is missed. This means carefully proceeding through the application of the plaster so that it is completely smooth and doesn’t have any bubbles which could present an issue later. With a professional plasterer, you can rest easy knowing that the plaster will be smoothly applied and that it will adhere correctly when applied over paint.

How to Prepare for Plastering Over Paint

So you’re all set to have your walls plastered now it’s time to begin preparing them. Check out the sections below to find out top tips on how to prep your walls for plaster according to the condition of the paint. That way your plastering professional can jump right in and begin the project!

Preparing When The Paint is in Good Condition

If your paint is in good condition, then the main thing you need to do to prepare for your professional to plaster over paint is clean. Overtime walls can become dirty, especially if they are in areas like the kitchen. Kitchen walls can easily pick up grease from cooking and steam. This can result in the walls becoming covered with dust or cooking oils.

The best way to clean this is with soapy water. Most times, a bucket filled with warm water and dish soap will suffice. Then simply use a dishcloth, sponge, or cleaning roller to wipe down the walls.

Then, simply let the walls dry and your professional will be able to jump right in and start applying the priming PVA which will help the plaster adhere firmly to the wall.

Preparing When The Paint Isn’t in Good Condition

If the paint on your walls isn’t in good condition all is not lost. You can still get the walls ready so that plaster can adhere to them. The primary step to preparing paint that is cracked, damaged, or peeling is to strip the paint. It is essential to strip damaged paint, otherwise, the plaster won’t be able to properly adhere to the walls, resulting in a renovation mess.

It’s far better to tackle prep work than risk the paint not adhering. Don’t stress if you aren’t able to strip the paint off your walls on your own. This can be a highly intensive process and is something your professional will be able to take care of.
