Subfloor Requirements/Floor Preparation
Subfloors and Underlayments - Laminate \ Laminate\Subfloor Requirements/Floor Preparation


NOTE: The following tests are required in commercial applications. Either or both tests are acceptable. NOTE: DO NOT use Armstrong ProconnectTM Professional Hardwood Flooring Adhesive when using Armstrong VapArrest Professional Moisture Retardant System S-135 or sheet vinyl as a moisture retardant. Use only Bruce EqualizerTM, Armstrong 57 Premium Urethane Adhesive. E. ROOM PREPARATION
  1. Though Armstrong and Bruce Laminate floors do not require acclimation, depending on storage conditions, it is advised that product being installed be within the same temperature range of room during service conditions.
  2. The room temperature should be at a minimum of 65F (18C) for 48 hours before, during, and 48 hours after installation.
  3. During and after installation, the room temperature should not exceed a maximum of 100F (38C).

  1. Removal of existing wall base, millwork or trim is optional.
  2. Door trims and doorjambs must be undercut to allow the floor to move freely. Use a discarded piece of floor and foam underlayment to support the saw blade at the correct height for undercutting (Fig.1).
  3. Sweep the subfloor and remove all dust and debris.
  4. If the drywall is slightly elevated at the floor and wall juncture, create a solid wall surface by fastening a 2" to 3" (5 cm to 7.6 cm) wide facing strip (such as 1/4" (6.35 mm) plywood) to the wall at the stud location.
  5. New wall base or molding must be installed at the end of the job to cover the 1/4" (6.35 mm) to 1/2" (12.7 mm) expansion zone around the perimeter of the floor.
  6. It may be necessary to plane or cut the bottom of the door to accommodate the change in floor height.
  7. Handle and unload with care. Store in a dry place, being sure to provide at least a 4″ air space under cartons which are stored upon “on-grade” concrete floors. Flooring should not be delivered until the building has been enclosed with windows, doors are in place and cement work, plastering and all other “wet” work is completed and dry.
  8. Although it is not necessary to acclimate Laminate flooring, prior to the installation it is best to store it in the environment in which it is expected to perform. Check adhesive label for adhesive storage limitations.

Install parallel to incoming light from any windows or, if lighting is not a concern, parallel to the longest wall in the room (Fig.2).

High Moisture Areas
It is a good idea to use 100% silicone caulk in areas of rooms where excessive moisture may be present, such as at kitchen sinks, dishwashers and ice makers. See Bathroom Installation section for instructions on Full Bathroom Installations (Section H).
