Hi all, has anyone had any experience with attaching old floor boards to a concrete slab? Any thoughts on the preparation and type of glue etc? Thanks.
50 x 50mm battens at 450 – 600 mm centres, not glue
We tend to rip up 70mm wide sheets of 17mm PLY. Lay black plastic down on your slab and fix these ply battens down at 450 -600 mm centres and fix every 400mm with a ramset gun. (Can use a drill and plugs if you have a loooooooot of time on your hands)
Now lay the boards as per normal. Boards up to 85mm can be secret nailed. ANything wider "Should" have 1 or 2 face fixed nails depending on width, but we use a combination of direct stick to the joists and secrewt nailing.These secret nailers can be hired.
Also don't forget to allow a 12mm gap around the walls and expansion joints for every 10 L/M or 100 S/QM. If you don't the boards could buckle. Allow these boards to sit on site for a few weeks prior to laying as well, this allows them to get acclimatised. Just as critical for recycled as it is for new boardsgood luck with the project

Thanks SNM & Adrien, much appreciated. Had not thought of the black plastic. Will stop the weeds too…….
Adrien,
I was just looking at your website, what finish did you use on the deck? Or is it the old trick of hosing things down for the photo shoot?
