Hi
I'm sealing a shower cubicle tray for the third time in as many years. Last time I used silicone sealer all around the tray and placed a right angled shower sealing strip (from focus diy) all around the tray above the silicone for good measure. The silicone has now come away from the tray so when the shower was aimed at a particular corner, the water goes behind the plaster under the cubicle and emerges downstairs out of a wall mounted light fitting immediately below - wondered why the fuse box kept tripping.
This time I have some plumbers mate putty I used to seal a sink waste outlet. I was going to push this into the gaps around the tray before I tried sealing it; does this sound sensible? Will it stay where I put it and maintain a leak proof seal or will it pull away like silicone always does?
What should I do after I have used the putty? I assume silicone sealer will not bond to it so would it be OK to just stick a decorative trim over the top of the putty and hope that the putty will maintain a seal on it's own?
Thanks
