I am finishing the basement in my home (3 years old) and will soon be ready for flooring. The basement is bone dry. There are a few small high spots in the concrete and I am grinding them flat and smooth. The floor is flat (save for those couple of high spots - 12" circumfrance at most), and has a nice smooth finish and no cracks, except for the zip strips.
I want to use a wood laminate in part of the basement and I want to put down a black and white 12" checkerbord tile pattern in another area (going for a 50's theme in that area ). There are no zip strips through the area I want to tile.
Should I seal the concrete before I apply either flooring material? Although the basement floor is perfectly dry, I understand I will still need a vapor sealer under the laminate, correct? If I glue, or use self adhesive, tiles for the tiled area, do I need to seal that part of the floor first?
You will need a 6 mil poly vapor barrier for the lam.
I would recommend VCT for the black and white.
No concrete sealer needed based on your info...
I am also going to be applying laminate in my basement, however I have one slight difference. I had a small seepage issue what has not been resolved but it left behind some mildew which has also been taken care of, should I seal the floor just in case???
