A couple of days ago, I started tiling my bathroom. I have porcelain tiles and I used BAL rapidset flexible. The first tiles I laid were on a plank of smooth planed softwood which I had used to make a shelf. When I checked it yesterday to see if it was stuck firm, it seemed a bit loose and when I applied mild pressure, the tiles just came straight off the wood. The adhesive was stuck firm to the back of the tile but it seems it didn't want to stick to the wood. What have I done wrong here? Can I not use this adhesive onto wood? I had already primed the wood with Granfix acrylic priming agent.
BAL adhesive on wood?

Rapidset Flexible is excellent & I use it all the time tiling directly onto WBP ply without priming. BAL recommends their APD primer for wood (as opposed to nothing with ply); this is an acrylic primer but the Granfix primer is also acrylic I believe so, in theory, it should have been OK. Something has obviously gone wrong, perhaps the Granfix primer has something else in it that Rapidset doesn’t like; it’s probably not a good idea to mix different manufacturer’s products, other than that I can't really say what's likely to have gone wrong.

agree with richard dont mix different manufacturers products.
i dont like tiling on wood, best to use marine ply or a sheet of wbp ply over the wood. bal white star should be fine for this. Or Bond-it do a brand for wood use called Aqua tile or wood flex which is preety decent.

I second that about tiling on to wood. One of my first mistakes was to do some boxing in with softwood... at least 2 things can happen:
If the boxing in is over a pipe that gets warm, the heat from the pipe can warp the wood, hence popping the tiles off.
When you apply the wet adhesive, the water gets into the wood and makes it warp, while everything's drying, again, popping your tiles off.
