We are laying laminate flooring. The flooring has a foam backing. The subfloor has some minor imperfections. How perfect does the subfloor need to be?
By Mike from Laurel, MD
The most common flooring surface that laminate flooring is installed over is the concrete slab. If the concrete slab is not flat the end result will be your laminate flooring "creaking". It is therefore vital that you check your concrete slab for flatness.
Don't think that the flooring underlay will take up too many of the dips or bumps in the slab, it won't. This really is the most important job in the whole installation process. Please take your time at this stage, it will pay dividends in the long run. Good luck. (03/22/2010)
I am not positive, but I think there is flooring mud you can use to fill those imperfections. I would think that the place you purchased the flooring from would be able to tell you what to use and how to use it. (03/23/2010)
