Technical Specifications
APPROVED SUBSTRATES
• Dry, completely cured concrete (at least 28 days old)
• Concrete and masonry blocks
• Cement backer units (CBU)
• Cementitious screeds, leveling coats and mortar beds
• Waterproofing and crack-isolation membranes
• Wood, plywood, or OSB subfloors that meet NWFA Subfloor
Guidelines and Specifications, and meet applicable building
codes.
• Cement terrazzo floors
PREPARING THE SURFACE
1. Be sure the subfloor surface is clean and dry.
2. In geographic areas where concrete slabs are subject to
excessive moisture, a calcium chloride moisture test is required.
Vapor emission readings in excess of 5 lbs. per 1,000 square
feet in 24 hours will require additional protection such as a
concrete sealant or polyethylene sheeting.
INSTALLATION
All wood and concrete subfloors must be flat within 1/8” over a 6’
span, or 3/16” over a 10’ span. All areas must be checked prior to
installation.
1. Roll QuietWalk underlayment over the subfloor with the vapor
barrier film (logo imprinted side) facing up to allow the laminate
flooring to slide easily over the surface.
2. The perimeter edges of QuietWalk need to be 1/2 to 3/4 inches
away from the wall.
3. Seams need to be butted together flush, do not overlap the pad.
Tape the seams with water and tear resistant, utility-grade, poly-
coated cloth backed tape that has a very aggressive adhesive
(duct tape).
4. Install laminate flooring according to the manufacturer’s
installation instructions.

Moisture Absoption Properties
Moisture Absorption Approx. 650% by weight
Moisture Statement. QuietWalk will absorb and allow dispersion throughout the product of water moisture in
accumulations not exceeding one gallon per 24 hrs per 300 square feet of product and/or allowed to continue to
accumulate for more than 7 days. Actual in-house tests have shown results up to 5 times that amount.
