Visti Posted February 19, 2020 Share Posted February 19, 2020 We're putting in a mezzanine with 6x2' beams (planed square edged) and looking to do the flooring as easily as possible. Any suggestions where I only have to install one later of board for a decent combined structural and finish floor? Or is T&G chipboard the most cost effective way to go, but with what on top?

ProDave Posted February 19, 2020 Share Posted February 19, 2020 I did mine with good quality plywood and then just sanded and varnished it. Link to comment Share on other sites More sharing options...
Dreadnaught Posted February 19, 2020 Share Posted February 19, 2020 (edited) @Visti, I can't remember, did MBC use Egger Protect T&G for your first-floor floor as they usually do? Would that be a sufficient finish? https://www.egger.com/shop/en_GB/building/product-detail/PROTECT Edited February 19, 2020 by Dreadnaught Link to comment Share on other sites More sharing options...

That is not a bad shout at all. I think I'll go with that. Mind some clarifications? - what grade and thickness of plywood did you use? - How'd you fix it to the beams? 7 hours ago, Dreadnaught said: @Visti, I can't remember, did MBC use Egger Protect T&G for your first-floor floor as they usually do?

Plus they are not the most cost effective solution! Link to comment Share on other sites More sharing options...

Mind some clarifications? - what grade and thickness of plywood did you use? - How'd you fix it to the beams? Mine is only 12mm thick. That's because I was trying to make the floor make up as thin as possible so have possibly under sized joists but lots of them, about 300mm apart, and wanted a thin floor as well. I just went to the BM and looked at all they had and chose the one that had a nice finish to the surface that I thought would sand and varnish okay. Fixed down with countersunk screws, as In I drilled a hole and countersunk the top with a counterskink bit before fitting the screw. 1 Link to comment Share on other sites More sharing options...
Visti Posted February 20, 2020 Author Share Posted February 20, 2020 Plywood it is. Just ordered 18mm for 400mm joist centers. Thanks for the idea Link to comment Share on other sites More sharing options...
Mr Punter Posted February 20, 2020 Share Posted February 20, 2020 Bear in mind that plywood is often 1220 x 2440. If you can get it metric sized it will save a trim-up. 1 Link to comment Share on other sites More sharing options...
