Hi everyone, Im renovating and because of runaway costs on ground works and roofing we are now on a seriously tight budget (ie nothing left) and whilst removing the roof, we also needed to remove the trusses which are seriously lovely wood, approx 4" x 6" x 6 meters+ long and I have 4 of them, plus other trusses slightly smaller at 4" x 4" but the same wood and same length (no idea what wood but its a hard wood and theres loads of it....) so, Ive done some research as I hate waste and love wood floors and recycling, and thought rather than scrapping it, burning it, or building a shed out of it, it would make a lovely end block floor especially as I have a budget for a simple kitchen or floor but not both. The one snag to this is, although I have laid floors before, laminate, floorboards, tiles etc, I have never done anything like this and the floor its replacing is a rather rubbish mix of floor boards, old quarry tiles and concrete. Its all level but Im not sure what preparation I have to do as all articles I find are for either wood floor (so they put down ply underneath which will then take it higher than the concrete and tiled areas) or for solid floors alone? Should I put ply down across the whole area to get a really flat level and a single surface or am I ok to lay directly onto the floorboards (which Ive secured with spax floor screw and it appears rock solid now) and simply continue onto the solid floors? What adhesive should I use? I have read a really good post on this forum from years ago, and like the idea of the oil/wax finish rather than varnish? Any ideas (other than telling me to steer clear?) Thanks in advance Mrs E.
