Hi
I've had some problems tiling onto chipboard. I'm using white cement adhesive & grout. Problem is the chip swells, presumably due to absorbing water from the wet cement, ruining the job. I cant see how one could stick the tiles down without using something wet. And even if I sealed the chip first, the water all has to go somewhere... and I could only seal under that tile, not the lot.
So how do I do this one?
Thanks, NT
Remove chipboard. Replace with waterproof backing of some sort.
If you can, then prime the chip with neat PVA first and let it dry. Also try using a standalone adhesive rather than a "fix 'n' grout" since these can be a bit on the wet side.
I used a few tubes of silicone sealant, keeping it away from the edges and grouting as normal.

thanks for that Lee. In this case it has to go on quite thick though... I'll try silicone and sand, the sand to increase rigidity.
