Adhesive advice

[urban]

Hey guys new member and already looking for advice. I recently tiled my bathroom floor and its now lifted again as the adhesive did not grab the floor (Chip board) nor the tiles Porcelin tiles. I used B&Q finest :mad2: Ultra bond rapid set. Now i have since lifted the tiles and put down some plywood so am looking for a recommedation on adhesive to use as i want this to be the last time doing the floor.

Any recommendations??

Thanks
Allan

It was 6mm

Welcome along. Sorry to throw another spanner into your dilemma but, a cement board would be a better choice for overboarding rather than ply, it is a much better surface to tile to. A deflection (bounce) free floor is essential for this to work so make sure your chipboard is well screwed down if you choose this route.

6mm ply is way too thin, 15mm is the British Standards minimum.

You would better off with 6mm hardie backer glued and screwed..

 

[jay]

as above the floor must be deflection free then 6mm cement sheet

15mm ply plus adhesive and tile would take the floor level to around 25mm high. This is not an option as this would cause a small step that i would like to avoid. I have screwed the ply down at 250 mm intervals and feels firm. Would i be daft to continue to tile over this?

6mm ply has far to much flexibility in it...

yep, you'll get deflection and warpage with 6mm ply, use hardiebacker 250, as mentioned above, glued and screwed

Your tiles will almost certainly crack if you continue. Hardiebacker 250 is the way to go as the other guys have said.....after lifting your ply first!!

it's a cement based board, you can probs get it from your local builders merchant

Hardie backer 250 glued and screwed is the way to go you will also be better off with a single part flexible adhesive such as mapei kera flex

most main tile stockists will be able to supply you with these.

what area are you in urban.
