Hi I have gutted a property and am now making it habitable. Upstairs I have put down new flooring. With the chipboard, underlay and engineered flooring, the height of this floor lays at 300mm. In the bathroom, a lot of the old floorboards were damaged by woodworm. So I will replace them with a marine plywood. The standard size for this is 180mm. I know you can get it in 220mm. However once the adhesive and tiles go down in the bathroom, I expect the floor should raise up a bit. Not being a tiler, I don't know by how much. I am using 60x30 tiles from Topps Tiles, link attached. http://m.toppstiles.co.uk/tprod46855/regal-ash-polished-60x30-tile.html I may be over thinking a problem that doesn't exist. However any advice would be good. Cheers IM
Mind your head on the door casings! The floor tiles for the bathroom will raise the level by about 15mm (150mm, if you prefer). But it does depend on the tile thickness. Normally about 10mm + 5 for adhesive.
Make sure the joists are ok then! Also, when tiling on a wooden floor, which can move, (as opposed to a concrete floor), make sure you use a suitable adhesive and grout... something that can deal with flexing! Regards, Cando
I would spray the joists with Everbuild Lumberjack triple action wood treatment, excellent product,from competitors. http://www.everbuild.co.uk/Triple-Action-Wood-Treatment Use a garden sprayer.
That sounds a little thick - guess you mean 18 or 22mm Don't use Marine Ply if you are going to tile on it. Yes, it is water resistant and stable however there is a better alternative Hardie Flooring. It is available in both 19 and 22mm and the boards are 2400x500 with a T&G interlock. You can tile directly on them, they are stable and easy to fit. https://www.jameshardie.co.uk/product/hardiefloor/
The time I have needed it, no problem. I found I needed a couple of days notice to allow it to be moved between branches, but if you are planning well ahead - no problems.
