dont know which method to install engineered floor on concrete i live in upland ca . float on cork or redux underlayment.or glued downadhessive 3 in 1 best overall methods
Which type of flooring (of the engineered) do you have? They come both ways and can be installed in the way they come. The flooring ( click and lock system) must be installed that way. Any other type, if they don t specify it, must be glued od stapled. And since you said over slab, it must be glued down. Each way works well, Just find the method you like since gluing can be messy and costly( for the glue) but easier for some people to install. And the floating system is a bit harder to do if your not handy. But is cheaper w/o glue. Any questions you can e mail me through my avatar. I ve attended several installation seminars as well as installed a few 100,000 s/f.. GL
