Do I need to prime old plaster walls before painting?

If you plan on painting old plaster walls, you will need to repair all damaged areas first by applying a high-quality patching compound specifically intended for plaster walls. It will also be important to use an oil-based or high-quality primer to stop any kind of moisture from staying with the wall.

Can you paint straight onto old plaster wall?

You need to seal your plaster in order to ensure the new paint sticks to the wall as you advise. I have the most success by cleaning the wall with a diluted emulsion and mopped it with a rag. It may be good to test a wall before applying paint on the whole surface to see if the result is good.

Do plastered walls need primer?

Any new plaster will need to be primed before painting. If painting a brand-new house, it is recommended that you wait 12 months before performing this process, as this will provide the walls and newly built dwelling time to set.

What happens if you don’t prime plaster before painting?

If you do not prime the wall, you can end up distorting the paint, especially in humid climates. Additionally, the reduced adhesion can make cleanup later much more difficult. You might find the paint wearing off as you are cleaning off fingerprints or dirt.

Do you need primer to paint previously painted wall?

You should only require one primer if the wall is smooth, clean and covered with the same kind of paint (both include oil-based paint, for instance). You should fill in and sand holes, spackle and patch drywalls if necessary.

Can you paint over plaster without sanding?

A certain amount of sanding is required to smooth out the wall surface before applying the plaster. Using only medium grade sandpaper can guarantee that the surface is free of any rough edges that could easily mar the paint.

It will take around 4 to 6 weeks for fresh plaster to completely dry out. Fresh plaster is slightly porous and will thus absorb moisture. If you paint over wet plaster, the paint may flake off.

Acrylic paint, latex paints, and acrylic paints are typically water-based, so they will realistically blend and seep into wet plaster walls.

Generally speaking, wall paint is more affected by plaster than plaster is.

Can you skim coat over old plaster?

Creative cracks on the surface of plaster walls can create voids that are too narrow to be patched with plaster, and they can also be not shown off with paint. One way to repair the surface is to skim-coat it.

Does a plastered wall need an undercoat?

Before painting on a freshly plaster wall, it’s highly recommended to use a base coat or an undercoat. Watered-down emulsion is an excellent choice as a thin base coat. There are also special paints available for painting on new plaster. If you apply paint directly on damp plaster, the paint will stratify into a seal on the wall.


In conclusion, when dealing with old plaster walls, choosing the right primer is essential to ensure a smooth and long-lasting paint job. The ideal primer for old plaster walls should have excellent adhesion, provide a suitable surface for paint application, and address any existing issues such as stains or imperfections.
