We are now in the 2nd year of our new home (new construction) and are looking to finish the basement. We plan on laying wood laminate floors down but want to make sure we do it right. When the floor was poured, they put a heavy mil plastic sheet down and poured on top of it (excuse my ignorance but I'm guessing that was a vapor barrier of sorts?). Basement was poured in the cold weather and the windows were all covered while we ran salamander heaters to keep the temperature toasty warm so the floors could dry. We do have concrete dust issues upstairs that we think will be alleviated after we lay the flooring.
My question is-do we need to do anything additional (waterproofing, sealing, painting) to the floor before laying the laminate floor? I want to make sure we not only have it properly prepped but also protected against any more concrete dust.
