Hi guys, quick question. We have been to view a job, with a solid wood floor which has been stuck. The owner wants Amtico putting down. How would you prepare the floor for the Amtico? Can it be screeded?
What about a 6mm ply on top instead? If took up would need to build up 18mm due to skirting/kitchen etc all on top of the wood
I don’t think covering a solid wood floor with a impervious vinyl is a good idea, 6mm ply or not Sent from my iPhone using Tapatalk
The wood needs to breath If you encapsulate it it can swell up and buckle taking the floor covering on top with it
A friend wants exactly same thing doing ... I say No, we need to uplift and replace skirting down to sub-floor
For educational purposes only: 1/ If it is stuck fast, why is this so necessary? 2/ What if for instance the wood was stuck very solidly, then the skirtings and fireplace had been fitted on top? 3/ If this was a commercial installation and safetyfloor was required on top of old parquet flooring which was stuck fast decades ago, would you guys still insist on taking it all up?
I spoke to Ardex tech support and tilemaster tech support, both said the wood can't be screeded directly, however if you put a 6mm ply over the top it would be ok. When I said I'd been advised that the wood floor needs to be taken up as wood floors need to breath, they then advised its always best to take it up
You can't lay any resilient or impervious floor coverings over wood flooring glued or not. If the wood cant breath moisture wil build up in it with nowhere to go and cause it to swell up and buckle. All existing floor coverings should removed at start fresh from the subfloor every time If you have anything build on top of the old flooring cut it out
absolutely correct too many cowboys out there if you have a slight height difference when concrete meets ply there is a flexible screed that can be used to go over the ply to level out the height difference
My client wants underfloor heating upstairs (joists), wants the levels to remain as close to current as possible. Would anyone say that a 12mm ply onto the joists, followed by a 6mm backerboard, followed by the electric mat, then the screed, then the Karndean is ok? It's the depth of the ply I need advice on more than anything else - would the combination of 12mm ply and 6mm backer be strong enough? Thoughts?
No way would 12mm ply be acceptable as a load bearing sub flor onto joists as spacey says 18mm min preferably 22mm
