Thanks Keithmac. If water soluble I guess I can wash it off and prime properly once dried then.
Can I use Mapei Primer G?
It's what is recommended to use with the tile Mapei Adesilex P9 adhesive I have. But can't see anywhere online whether or not I can use this for tiling in a shower.. hoping...
Complete noob
I've seen a lot of posts about PVA v SBR to prime before tiling. Saw them too late. I somehow managed to apply a coat of diluted febond pva over wall's I'm intending to tile in a shower. One wall is stud/plaster, the other is brick, rendered and painted.
Did I completely fluff...
