I have just completed a removal of old grout from my shower recess, but in the process I have scratched some water proofing layer behind the old grout.
What is the best way of sealing it before I put the new grout on?
The groove (spaces) between tiles are not wide enough for paintbrush to put a new layer of water proofing material. The water proofing paste is to thick to put in such a small groove.
I have some bondcrete I could apply with a tiny paint brush. Is this sensible? It is not suitable for wet areas, but if there is a layer of grout in front of it, it should not get wet with regular use of shower.
if I do this will the old grout still stick ok?
I have also bought the grout sealer to put over the grout; to minimnise any chance of water going behind the tiles.
Anyone with experience/comment will be greatly appreciated
