 Re: Wall Sealant Prior to tiling? | |
If in doubt, prime the walls is a general rule. You didn't say what adhesive you are going to use but one thing that is ABSOLUTELY DEFINATE - DO NOT USE PVA.
Use a "proper" acrylic based tiling primer sucha s BAL Prime APD or Ardex P51.
PVA is not suitable for tiling for various reasons and this has been debated many times here in the forum. Do a "search" in the box at the top for "PVA" and see what comes up.
You new plaster area should definately be primed. The tiles area should be cleaned with sugar soap and dried off. As you are tiling onto tiles it is wise to be using a flexible adhesive such as BAL white star. This would be adequate for all the walls but the area you are tanking would be best to use a powder adhesive not tubbed. Alternatively use a flexible powder adhesive everywhere or a standard adhesive with a flexible admix. |
