Cement Crack Sealer or Cement Resurfacer to fix a 1/8" crack
I am preparing my cement subfloor to install a laminate floor. I have a 1/8" crack about 8 feet long. I don't see a noticable difference in height of both of the sides of the crack, however, it does look like the crack is very slightly raised up.
I called the company and they are telling me that I should not use any of the above because they are caulk based and are not meant to be covered. They said that I should be using the Vinyl cement patcher or the quikrete cement resurfacer.
What do you think is the best way to handle this crack, before I put down the underlayment and laminate?
