Hi,
I just replaced the silicone sealant along the front of a relatively new shower (6 months old). The reason for this was that the plumber got a big lump of dirt off his boots into it when it was wet.
I managed to cut the old out with a very sharp craft knife, this still however left a very thin film of the old stuff on the shower tray and door. I masked it off and applied the new stuff about 1mm wider than the old.
Is this going to be OK, I've started to worry that it may not adhere properly to the old silicone??
Any comments welcome.....
Pete
