Ok here's the scenario. I have a shower in my attack en suite. I have retiled it twice. The first time was on MDF long before I knew what I know now. I stripped all that out and reboarded using waterproof plasterboard about 5years ago. Unfortunately there is an issue with my joists which has led to some deflection and the silicone join between the tiles and the shower tray has failed allowing water to get in behind the tiles.
To to take all the tiles off and reboard it is a massive job and we are looking to sell up and move. I won't say I intend to bodge it but I do want to know your thoughts not from a technical point of view as I know what I am going to do is not technically the right thing to do. I want to get an idea of your gut feelings as to whether it will work or not.
right... I can afford to lose a bit of space so I was thinking of buying some 10mm marmox and glueing it over the existing tiles and then mechanically fixing it through the tiles into the timber studs behind. Before sticking it on I was going to tank the existing tiles. Then a second tanking coat over the marmox. At the bottom where the marmox hits the shower tray I was going to run a bed of silicone and push the marmox into it. Then I was going to tile it using a reasonably light weight ceramic or porcelaine tile.
Bad practice aside what do you guys think.... Does it stand a chance or not?
