I have always used 6mm Hardi backer board on timber floors, but since my local B and Q no longer stock it I bought some 6mm No More Ply from Tile Giant.
My method of laying the NMP was as follows....New 22mm chipboard flooring fitted to joists, all glued and screwed floor had no deflection solid as a rock.....Chipboard cleaned and primed with SBR....NMP cleaned and fixed with Keraquick using a 6mm notched trowel, then screwed 200mm centres with 25mm Turbo Gold screws. All joints staggered with 2mm expansion gap.
Bought 1 tube of the polyurethane adhesive and used it only for the joints, then scraped off the excess the next morning.
Really wasn't sure what to do with the joints, as I always tape the Hardi board joints. The NMP boards have a really smooth surface and I found that the screw heads did not penetrate the surface and finish flush. However, a quick jag with a 10mm twist drill before inserting the screws made a huge difference.
Over all, I quite liked the NMP, and would use it again but I would like to ask you guys what you think about my installation method, and in particular what you all do with the joints prior to tiling. Cheers Gavin.
