Most people plaster the walls before priming or painting. Some try to plaster over the tiled walls. It is possible to plaster the tiled walls, but you must ensure that the tiles can hold the additional weight of plaster coatings.

Imagine you plan to remove the tiles before plastering walls and notice some adhesive residues on the wall. If you are wondering whether it is okay to plaster over tile adhesive, you found the right blog!

Yes, you can plaster over the tile adhesive, but there are some preparations you need to make beforehand so that the plaster adheres to the surface. A tight-layer hard wall over the tile adhesive will help the plaster stick to the wall. However, removing as much tile adhesive from the substrate before you plaster is better to avoid risks.



Plaster is made using gypsum, water, and sand. You can use it to coat the partition, walls, and ceiling. The plaster will harden once it cures. A freshly plastered surface will take one to two weeks to cure completely.

The curing time may vary according to the surface type, the coating thickness, and the climate. Following are some pros and cons of plastering the walls:


  • Plastered walls are a long-lasting solution due to the sturdiness offered by the plaster.
  • Plastered surfaces are moss-resistant and could be painted over to enhance the look. The thickness of the plaster coating might contribute to soundproofing.
  • You can easily clean the plastered walls without causing any damage to the surface.
  • It also provides an elegant look to the house by creating a smooth and even surface.


  • Painting over the plastered surface might be hard. Therefore, it is necessary to coat the surface with the right plaster thickness to paint it perfectly.
  • If the plastered wall gets damaged, you might have to spend a lot of money hiring an expert plasterer to fix the issue.
  • When compared to drywall coating, plaster coating is more expensive.

The struggle is true when removing old tile adhesive from the surface. Due to the difficulty of removing the glue, some people try plastering over the old adhesive residues.

Step 1: Remove As Much Adhesive As Possible

After removing the tiles, remove the tile adhesive from the surface.

Then apply a coat of bonding agent (hard wall) over the wall and the adhesive residues. 

This bonding agent will help form a strong adhesion with the surface and the plaster coating.

Note: You may also add PVA glue before applying the coat of bonding agent. This step is optional but will help obtain a better surface.

Step 3: Apply Plaster

You can start plastering over the wall and tile adhesive when the bonding agent dries well.
