Just stripped out a tiled shower cubicle, the tiles were put onto plywood, and had an ok bond. Ive overboarded with Multipanel now but theres a half foot gap at the top that wants tile with some porcelain tiles.

I cant really replace it with cement board for various reasons.

I have Primer G and Keraflex s1 already for the plastered walls as only seem to be able to get Mapei stuff around here.

What can I use to securely stick these tiles?

Cheers

Seriously though, it's just not a good idea - ever.

Yes I know its not ideal but I have no choice. Theres no other way. So need to figure out what people use to do it well.

The cubicle I had just ripped out was tiled by someone onto plywood over 15 years ago, and they wernt that easy to chisel off. Literally had to get the sds out in some places.

Your problem will be that 15 years ago, plywood was generally good with a decent thick top layer of hardwood.
Nowadays it is so dodgy that it's just not worth the risk.
Personally, I would never tile direct to plywood in any circumstances.

Just Rizzle

the only ply that you could possibly tile on to is sp101 flooring grade ply used in the LVT industry

ive replaced what I can with Hardiebacker but theres still a 2m by 15cm strip to tile. This cant be replaced.

Anyone used Mapei Eco Prim Grip or Primer S on plywood?

I really need a way to make them stick with the best chance possible.

Perfect Tiling

Just a thought.......if your'e tile in a shower cubicle why dont you tank the whole area first with a waterproof coating such as Ardex. I always tank shower areas with Ardex or Mapie aquadefence. These stick to absolutely anything and surely this will mean that your'e not actually tile onto the plywood. Its always a good practice to waterproof shower areas anyway......

Too risky with ply nowadays. Just not worth it.

Think of the cost to replace if it fails vs the cost to do the correct prep initially. Ripping up and replacing after installation is a whole world more money.
