Hey SuperPav, Thank you for your great answer. I found 22mm tongue and groove plyboards that are 240cmx59cm. I will replace the upstairs bathroom subfloor in the next one or two years when I renovate it. I am just wondering if it makes a big difference between the 22mm p5 and the 22mm plywood? The price being the obvious. The weight might be another one?

Hello, I just bought a house in Bedfordshire and took all the carpet out on the first floor. The floorboards are from around 1965 and were lifted a few times in places for wiring. Many are broken and the floor is in general very uneven due to the boards. I lifted some boards and the joists look good. They are appr. 38cm apart in the center. I want yo lay bamboo parquet and need a smooth subfloor. I decided to replace the floorboards in the 3 bedrooms and the hallway (appr. 33m2) which are appr 20mm thick. All boards are dry snd so are the joists My questions: 1. Which material should I use? - 18mm osb 3 t&g -22mm plywood t&g -22mm p5 t&g Do I need a planning permission on can I just crack on? 2. When I lift the boards up, is it worth it to paint the floor joists? If so with what? I thought it might protect them. 3. If I use plywood boards, would you paint them with a varnish before installing the parquet? Any help is much appreciated!
