Specification Sheet

INSTALLATION INSTRUCTIONS
The following installation instructions are a recommendation and are not intended as a definitive project specification. They are presented in an attempt to be
used with recommended installation procedures as published by the Resilient Flooring Industry. For use with Resilient Plank and Tile only, NOT for use with
resilient sheet goods.
SITE CONDITIONS
The installation site must be acclimated, with the HVAC system in operation.
The floor and room temperature, as well as the Hush II underlayment, flooring
materials and adhesives must be maintained at 65 to 85 degrees F and the
relative humidity below 60% for a minimum of 48 hours prior to, during and
after the installation.
SUBFLOOR
1. All substrates shall be smooth, structurally sound, permanently dry, clean
and free of all foreign material such as dust, wax, solvents, paint, grease,
oils, old adhesive residue, curing and hardening compounds, sealers and
other foreign material that might prevent adhesive bond.
2. Concrete subfloors shall be flat and smooth within 1/8” in 6 feet or
3/16” in 10 feet.
3. Wood subfloors need to be structurally sound and in compliance with
local building codes.
4. Inspect concrete subfloors for any open cracks and fill with a high-grade
epoxy filler or polymer modified cementitious floor patch.
5. Lightweight concrete subfloors must be free of structural cracks and
prior to the application of an adhered underlayment or finish floor, must
be primed with two coats of the SHAW 9050. If the underlayment is
loose laid, priming is not required.
6. Remove any excess lumps or residue from the subfloor that may
interfere with the installation of the SHAW Hush II underlayment or
would possibly “telegraph” through the finished flooring.
TESTING FOR MOISTURE – CONCRETE
• Calcium Chloride test method per ASTM F 1869 or In-Situ Relative
Humidity test method - ASTM F 2170 test must be performed.
• Lightweight concrete: Internal Relative Humidity – Tests should be
performed per the latest edition of ASTM F 2170. Three internal relative
humidity tests should be conducted for areas up to 1000 s/f.
• Maximum moisture content — CaCl 5.0 lbs. and/or 85% RH per ASTM
2170
PERIMETER ISOLATION
It is important that the finished flooring not directly contact the perimeter
walls or vertical partitions of the entire floor area, including any openings or
protrusions such as electrical boxes, heating ducts, cold air returns, columns or
pipes in the subfloor installation.
Perimeter Isolation can be achieved by leaving at least a ¼” expansion gap
between finished flooring and the fixed partitions or walls.
RECOMMENDED ADHESIVES
All Shaw LVT/LVP adhesives
INSTALLATION FOR GLUED DOWN LUXURY VINYL PLANK
AND TILE ONLY (Double –Glue)
1. Cut the SHAW Hush II roll material to the desired length and position
the material in the space to be covered.
2. Proceed to cover the entire room, making sure the sheets are tightly
butted together, without gaps. Open seams and gaps will “telegraph”
through most vinyl products so the underlayment work must be as
smooth and well seamed as possible.
3. Never mechanically fasten the sheets to the subfloor, as this will severely
diminish the acoustical value of the product.
4. Pull the loose laid material back at least half the length of the cut
material and apply an approved adhesive to the substrate.
5. Use a 1/16” x 1/16”x 1/16” u-notch or square notch trowel and allow
adhesive to properly flash off. Note: For lightweight concrete primed
with Shaw 9050, or other limited porosity substrates, use a 1/16” x 1/32”
x 1/32” u-notch trowel, making sure to completely cover the substrate.
Allow a 30 to 40 minute flash time and install the Hush II underlayment
while the adhesive is partially, but not completely dry.
6. When using SHAW S150 spray adhesive spray an even amount of
adhesive on the subfloor (approximately 125—150 sq. ft. per can) and
allow the adhesive to dry to the touch before installing the Hush II
underlayment.
7. Install the underlayment and upon completion roll the material with a
roller (75 lbs. or less) to insure contact with the adhesive.
8. Hush II underlayment should cover the entire floor area without gaps
and be securely bonded with the joints tightly butted.
9. Allow underlayment to cure for a minimum of 3-4 hours.
10. After 3-4 hours you can then proceed to install the luxury vinyl tile or
plank following resilient installation guidelines for a non-porous substrate
(adhesive in pressure sensitive mode).
INSTALLATION FOR FLOATING RESILIENT FLOORS (Residential
application only) Commercial products – underlayment must be full spread prior
to floating vinyl products.
1. If the underlayment is to be loose laid, the seams should be securely
taped and it may also be advisable to bond it to the suboor at the
perimeter, doorways and or areas that transition into other ooring
materials, using either an adhesive or commercial grade double faced
tape.
2. Cut the SHAW Hush II roll material to the desired length and position
the material in the space to be covered, proceed to cover the entire
room, making sure the sheets are tightly butted together, without gaps.
Open seams and gaps will “telegraph” through many resilient ooring
products, so the underlayment work must be as smooth and well
seamed as possible.
3. Once the underlayment is installed on the suboor, care should be
exercised to avoid having it move or shift during the installation of the
nished ooring. Follow resilient installation instructions for installing the
nished ooring product.
4. If a rigid baseboard or shoe molding detail is required, leave a minimum
1/8” gap between the nished oor and the bottom of the quarter
round or baseboard molding. This gap can be lled with a non-hardening,
color matching, paintable or clear Acoustical Grade Sealant.
