Which plywood do i use over old floorboards before tiling?
I want to put quarry tiles on the kitchen floor of a first floor flat on top of very old floorboards. I have bought flexible adhesive and grout but I am need advice on which plywood to use to make the floor secure, waterproof and soundproof. I would be grateful for any help. Confused Lady.
Hi, I would not use plywood this is a thing of the past and does come with problems if not fixed or laid correct,I would recommend cement fibre board such a Marmox,Hardibacker or Aqua panel,this can be glued using tile adhesive and screwed giving you a much better substrate local tile shops will put you right on this ,have a look on you tube for videos of this product.

Plywood is fine to use - I would use a 8ml or more depending on the floor boards you are plying over this will make your floor more sturdy less movement, when fixing use small screws 15ml then put each screw about 300 ml apart use more if needed.
