Best answer

If your wall has been plastered recently, make sure it has been left for at least 14 days before tiling on new plaster. If this isn't necessary, a coating of sealing primer directly on the plaster will ensure a decent base, just make sure you give it 24 hours to dry.

Asked By: aL3xa Date created: Jun 19, 2022
