tile on chippie

[poshman]

hi helpers, yes i know i shouldnt tile on chipboard but my en suite is only 1.2 mts x 1.5 mts so the walking space is probably a third of that so will only be standing on about 6 31cmx 31cm ceramic tiles.



I had it tiled about 12 years ago by a "pro" and he just tiled straight on it

so if i remove all the adhesive off and put extra screws in chipboard to make it more solid and use 2 part bal fastflex you think it will be ok or is it too much of a gamble ?



if its to much of a gamble and i take it up and put wbp ply down how would i support the ply all around the edge of the skirting where the ply meets the chipboard



thanks for your help P M

Overboard with 12mm ply.

for peace and mind. I would pull up the chipboard. Then replace with 22mm wbp plywood. Then use a good SPF adhesive.

Well don’t do it then , the advice you’ve been given is sound.

However; it’s so small an area, an option may be to fix some 6mm HardiBacker boards over the chip & tile over that but I wouldn’t tile straight back on the chip. Don't come back & moan if it goes wrong though cos, frankly, you’d do better to loose the crapboard altogether.
