I have a sealant problem that I hope someone can help with. Every time I reseal around my bath, no sooner have I done it but it needs to be done again (within weeks starts to have gaps). If I can just explain more - when I get in the bath and it's full of water, the bath drops a millimetre to even 1.5mm down one side, so the sealant comes apart after a couple of weeks. (Before anyone thinks I'm a big fatty who needs to lose some weight, that couldn't be further from the truth, I'm really small). I've tried doing it different ways, the last time I left the bath full of water and resealed in the 'sunken' state. And in the past I have resealed with an empty bath too. Neither makes any difference. If I take the bath panel off you can see underneath where water has gotten down because of this problem. Anyone had experience of this? What can I do? Cheers.
