D. SUBFLOOR REQUIREMENTS
Armstrong and Bruce Laminate Flooring can be installed over most subfloors and existing floors on all
grade levels.
All substrates must:

meet applicable building codes

be structurally sound

show minimal deflection

be dry, clean and flat
Precautions:

Armstrong & Bruce Laminate Flooring may be installed in bathrooms following the guidelines
outlined in the Bathroom Installation Section H.

Armstrong & Bruce Laminate Flooring are not recommended in high-humidity areas where the floor
is normally wet (e.g., steam rooms, or saunas.)

The slope should not exceed 1" in 6' (2.54 cm in 1.83 m).

Variations in subfloor flatness should not exceed 3/16" in 10' (4.76 mm in 3.05 m) or 1/8" in 6' (3.17
mm in 1.83 m). Level floors with a suitable cement-based self-leveling underlayment following the
manufacturer’s recommended guidelines.

Radiant heated subfloors should not exceed 85°F (29˚C).
Concrete Subfloors

Concrete floors must be cured properly and allowed to dry for at least 60 days before installation
can begin.

Concrete floors must not show any signs of moisture or alkali.

Use Quiet Comfort or Quiet Comfort Premium Underlayments for Laminate with no-attached
backing (or Moisture Barrier Sheeting for laminate with attached backing), butt the edges together
and tape the seams with polyethylene tape.
 All concrete subfloors should be tested, and results documented, for moisture content. Visual
checks may not be reliable. Test several areas, especially near exterior walls and walls containing
plumbing. Acceptable test methods for subfloor moisture content include:

Tape 3' x 3' (91 cm x 91 cm) pieces of polyethylene film to the subfloor.

After 24 hours, if moisture condensation appears on the film or the concrete appears dark-colored,
it is likely excessive moisture is present and a Calcium Chloride test must be run.

Tramex Concrete Moisture Encounter Meter: Moisture readings should not exceed 4.5 on the
upper scale.

Calcium Chloride Test (ASTM F1869): The maximum moisture transfer must not exceed 5
lbs./1000 sq. ft. in 24 hrs.
