Recently installed a new shower screen (about a month ago) as the old one leaked and everthing was ok until today. Looks like there is a gap in the sealant allowing water to drip down the back of the bath and run along the floor finally dripping down into the living room below. Is there any fool proof way of completely sealing all possible leak points. Must have used half a tube of mastik now and have run out of ideas/patience. Any help/advice is greatly appreciated.
