hi all, did a bathroom and a kitchen floor this week. Used standard set addy which gave me a bit more time to work. Left it for a good 24 hours before grouting Plywood subfloor installed by joiner and sealed with latex sealant by me before being left to dry and then tiled. Grout in bathroom fine but grout in kitchen showing lots of cracks. Went back in today and mixed grout a little thicker in case that was the issue, raked out affected areas, cleaned and re-grouted. Been back to check and although not fully dry it's not as bad but still cracking has appeared. Heating on full bung so wondered if it's dried too fast? Alternatively, could it be movement on the sub floor?
Any suggestions appreciated
