I grouted a test area with the BAL WJG mixed with GT1 carefully weighed out and measured. A couple of days on it was still not hard i.e. a screwdriver would easily squash into it almost like pressing into biscuit (not really that bad but you get the idea). I think there could be something wrong with that bag of grout. 2 weeks on it was still not hard as grout should be. As I needed it repaired fast I bought MAPEI ultracolor plus for only £3. The literature states swimming pools can be filled after 48 hours rather than the 2/3 weeks stated on BAL WJG. The grout went off so quick I barely had time to get it done! I left it 4 days just to be sure it was cured and treated it with HG waterproofing grout sealer to improve it's water resistance. I intend to completely replace the bathroom in a couple of years so it should be OK till then. Will probably use MAPEI in future. Thanks for your help.
