Browse Forums Flooring & Floor Covering 1 Feb 12, 2012 11:29 am Hi all, I'm having strandwoven bamboo floating boards installed shortly and I have a question about the quality of my particle board subflooring. I recently removed the ceramic floor tiles (which was possibly the most back breaking task I've ever performed) where the bamboo is to be laid - unfortunately there was no backer board, the tiles were glued down directly onto the particle board. I have subsequently scraped off most of the glue (it's black, not sure what kind of glue it is) and the surface of the subfloor is pretty flat. However where the remnants of the glue remains, the floor is perhaps 0.5mm raised in patches. I've got no idea how I can flatten these patches out as this is as good as I can get it with a scraper. Does anyone know if this slight unevenness is likely to cause a problem with the floating board installation?? The underlay will be 3mm thick, which I would have thought would absorb any slight unevenness in the floor surface??? Any help will be much appreciated!!

Hi MrZebra, It's best to seek this advice from the contractors that are doing the job for you as they are the ones it could come back on, if not installed correctly, but as a general guide, floating floors require the floor to have undulations of no more than 2-3mm per running metre. So by the sounds of it, you shouldn't have a problem. In saying that, the flater the better. You could hire a grinder from the likes of Kennards and grind back the higher areas just to be sure if you like, far more effective than a hand tool. Good luck with your new floors.

This adhesive is difficult to get off - mostly because its such a thin layer that I can't get a scraper under it without digging out chunks of particle board!! I include some photos below where I've had a good scrape at it and I think it's pretty good. If you were to run your hand over it you wouldn't so much register a change in height, but rather a change in texture: Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ And here is an area where it's quite a bit worse - hasn't been scraped yet: Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Re: Subfloor preparation for floating boards 4Feb 12, 2012 9:24 pm Looks Pretty good from this view, should be ok. Word of caution on the edge. It looks like you'll need to use a senior end trim rather than beading against the low profile skirting. Is that where a floor to ceiling window is maybe ? Anyway, your layer will know what to do.
