About 15 years ago, I tiled my upstairs bathroom using porcelain tiles over a chipboard wood subfloor. At the time, I used a ready-mixed flexible adhesive from Wickes (Wickes brand) that was specifically for wood substrates. I can’t seem to find anything similar now, but I have to say that it worked incredibly well. Removing the tiles was a nightmare. I ended up breaking them off and using a heat gun to soften the adhesive, which became elastic and peeled away rather than crumbling like cement-based adhesive. It seemed like a great product.
I’m now renovating the bathroom again and getting ready to lay new tiles. This time, I’m planning to use a decoupling membrane. It has a fleece backing (which I understand should be bonded to the floor) and a honeycomb-style surface on top, where the tile adhesive goes before laying the tiles.
My questions are:

My questions are:
- What’s the best way to bond the fleece-backed membrane to a chipboard subfloor?
- I have a C2 S1 cement-based adhesive (powder that needs mixing). Is this suitable for fixing the membrane to the floor?
- Should I apply a primer to the wood substrate first? If so, what type of primer is recommended?
- Can I also use the same C2 S1 adhesive to fix the tiles to the top of the membrane?
