Hi, would appreciate opinion on bath to tile waterproofing repair.
Basically a leaking old bath strip - was a rigid under-tile version. Having read through the forum decided to cut it back flush to tiles. Worked ok but shown up larger gap at tap end (up to 9mm) than at the side (4mm).
Steps I think need doing:
1) Bit of expanding foam behind tap end of bath. Bath is solidly on wooden frame up to walls and doesn't move - but one of those old models where edge curves down to the wall.
2) Cut foam back and silicone bath edge to foam/plaster/strip remnant.
3) Where it becomes a hassle. I think gap is too large for a tile-bath bead, so either put a tile 'skirting' strip over existing tiles, just 2mm off bath (found just about enough offcuts in loft to do this) and bead top of it? Or something else?
Problem is existing tiles fixed using a corner strip, so however I do it seems to leave problem of ensuring corner is fully tight esp meeting bath. Tap end tiles fixed to boxing, so as water has been getting through think trying to get them off might pull chunks of wall out and not enough tiles to redo whole thing.
Have attached pics (I've taken off corner strip, so what's visible is base it fits on). Will look at replacing whole room in couple of years, but can't afford it now. In meantime most important is getting it watertight rather than looking good. Any opinion greatly appreciated. Thanks.
