I recently resealed my bath following all instructions i could find on the web and on the back of the sealant tube. I stripped back all the mouldy nasty sealant using some sort of stripping chemical. i then cleaned the area thoroughly and used meths before i sealed it again. Have left it 3 days and had a bath last night and now the sealant has turned into mush - a consistancy much like toothpaste! I really dont know what I've done wrong?! It was a very hot bath and there was a lot of steam but i still dont know what happened. The only thing I can think it might be is if there was some meths or some of the sealant stripper on the walls above the sealant and its run down with the steam? Am so fed up : (
