Q: My husband is installing our engineered wood flooring by gluing it down. We have a concrete slab with linoleum, which he coated with a concrete leveler rather than remove (we didn’t want to mess with asbestos). We are about 1/3 finished with our front room and when walking on it, I noted there is a spot where the floor is uneven slightly and the wood is not glued down.
When I stepped on it, the two boards over this uneven ground ever so slightly sunk and made a crack/snap noise. It is too small to crack the wood but enough that when walked over will make a noise every time. What can we do? I don’t want to have to pull up everything we have down already to level the floor. Can we nail each board into the concrete, using a drill to make the hole first?
He also suggested actually cutting out one section of the floor and replace it after leveling the floor? That doesn’t sound ideal to me, because I know it won’t go unnoticed.
A: Drill a small hole and use an injectible adhesive. Any number of adhesive manufacturers likely make something suitable for this. Perhaps Bostik Findlay or Vermeister etc.

Level the floor without ripping it out
We just ripped out carpet from our hallway. We discovered the floors had been finished, but the floor is not level. Is there anyway to level the floor without ripping it out?
Loose boards due to a dip in concrete subfloor
I recently installed hardwood planks on to concrete with glue. I did level concrete first, but evidentially missed a spot as I now have some loose boards due to a low spot. What's the best remedy to fix these loose boards?
