Floor covering installations and small amounts of moisture vapour do not mix. NFCA Floor Covering Installation Standards state: New (and existing) concrete substrates must be properly cured and thoroughly dry before commencement of any flooring installation. As curing depends on such things as environmental conditions, location of the slab and the time of year, substrate surfaces may require more drying time than normal before they may be considered ready for moisture testing. While curing to design strength typically takes 7 to 28 days, drying time for floor coverings can take many months. Allow a minimum 1 month of dry time per 1” of slab thickness (1 day per 1mm). Knowing this a year in advance helps the planning process. Finding out a month from project completion when the floor contractor is scheduled to start work is bad news for all involved. www.nfca.ca
