Sub-Floor Preparation


  • Check for moisture content using the appropriate testing method. 
  • A new concrete slab usually takes 90 days or more to dry thoroughly depending on slab size and weather conditions.
  • Sub-floor must be flat, dry, free from residues and structurally sound.
  • A moisture barrier must be used. 
  • SOLID PLANK FLOORS: Nail down plank flooring must have proper sub-floor over the concrete. Planks cannot be directly glued to concrete. Planks cannot be short to the concrete.
