Sealing the cut edge of tiles before re-sealing Advice and information on tiling and fixing tiles to a variety of surfaces

After some 18 months much of the the silicone has let go from where my cut tiles meet the shower tray on the tile edge only, not from the tray.

I have removed the old silicone and intend to clean all accessible surfaces with methylated spirit before re-applying silicone. Do I need to apply tile sealer to the cut edges of tiles to improve silicone adhesion? Will tile sealer damage the tray?

Hi bloodoo
Suggest you use silicone to seal the tile edge - apply with a stiff artists brush, allow to cure then apply the main bead.

Thanks Stoneyboy.
I can manage that on the wider gaps but more difficult on the thinner (2mm-3mm)gaps.

Hi bloodoo
On the thinner gaps run a bead of silicone along it and feed this in with a knife blade, clean off the excess and leave it to set. With a gap that narrow nothing will be perfect.

Thanks Stoneyboy, I will give that a try
