Q: I am installing a 5″ plank engineered wood flooring in my home. It is hand scraped wood that is supposed to be glued down. The house has a slab foundation and part of the subfloor is covered with old vinyl tiles, and the other part is old VCT 9″ asbestos tile. It is all glued down with cutback and is very securely affixed to the slab. It is not coming up.
Because of this, my plan is to level it all out with self levelling concrete, and lay the engineered wood directly on top of the old flooring. I will be using Bostick’s Best adhesive. Do you see any problem with this? Will the adhesive properly adhere to the old VCT tiles? Should I (if possible) put a skim coat of the concrete over the top of the tiles to help adhesion? Any other ideas/suggestions?
A: That is an interesting question. It makes me a tad nervous, because the installation of any floor will only be as secure and stable as the sub strait it is sitting on.
My best advice, what I would do, is call or email Bostik-Findley and ask them for their recommendation regarding Bostik’s Best.
