Which brings me back to my original question. If you know its going to crack, i.e fail then why "bond" your silicone over the top?
Would this not jepodise the integrity of the sealant?
If its clear over grout for colour then use a colour co-ordinated silicone surely??
Confused.com
the silicone is sealed to the tiles either side of the grout. I don't see why a 0.5mm crack in the grout would jeopardise the integrity!?! I could be wrong, but until I see it fail, I don't see any reason to change my methods.
and... Not one person on here has even said they've seen tiles tenting by doing it my way!?!
ok here goes any one that sillcones in the joint or on top of tiling after grouting is waisting your time as it will pull out over time or will pull off the surface in time and let water through so the right way to do this is to silcone the wall or floor joint before you tile then lay tile into wet silcone sealing it behind the tile and the substrate so it can never peel off now you can grout or sillcone the joint and now that there is one layer that will never fail as its pinned in place now thats real tanking at 1 % of the cost
Ray, I agree that would be the most watertight method. Same as you do when you instal a bath, or basin. But..... Surely, by totally filling the void with silicone, you've removed the movement joint, as there would be nowhere for the silicone to compress into!?! Not that I have any problem with that, of course... Lol
