Specification

the manufacturer’s instructions. Refer to ASTM 710 Standard
Practice for Preparing Concrete Floors.
Wood – Subflooring, such as APA underlayment grade plywood,
hardwood, oriented strand board (lightly sanded), or other materials,
must be flooring grade and installed to the manufacturer’s
specifications with adequate ventilation and moisture protection.
Cracks, chips and joints must be properly patched or repaired.
Ensure the appropriate flatness/smoothness to prevent accelerated
wear. Existing vinyl composition tile must be limited to one layer and
well bonded. Remove all wax, floor finishes, dirt and contaminants that
may interfere with the bond. Refer to CRI Carpet Installation Standard
available at www.carpet-rug.org.
Expansion or other moving joints must not be filled or covered
with flooring.
General: Ensure substrate, flooring material and adhesive are fully
acclimated prior to installation at the same temperature and humidity
level expected during normal use (between 65–95°F / 18–35°C with a
relative humidity (RH) of no greater than 65%). Refer to flooring
manufacturer’s specific recommendations and industry standards.

The trowel notches referenced are those typically recommended for the type of flooring being installed. They are
normally the minimum size recommended. Surface conditions (roughness and porosity of substrate), type of flooring
and backing will ultimately determine the required trowel notch size and coverage.
Flooring manufacturer’s products differ in characteristics and textures. Always check with the specific flooring
manufacturer’s recommendations for their specific trowel requirements. Less porous substrates typically require
a smaller notched trowel and longer open time than porous substrates. Ensure 100% transfer of adhesive to the
substrate and the flooring backing. Refer to Roberts Double Bond Installation Guidelines for trowel notches.

Substrates: Concrete, APA underlayment
grade plywood, vinyl composition tile (free
of wax), primed gypcrete and terrazzo.
Check with the flooring manufacturer for
their underlayment recommendations.
Surface Preparation: Subfloors must be
structurally sound, dry, smooth, flat and
free of excess moisture/alkali and all
substances (oil, wax, grease, oil based
sealers, adhesives, etc.) that might
interfere with the performance of the
flooring or its installation.
All substrate cracks, holes, high spots and
irregularities must be adequately repaired
to ensure a smooth, finished appearance
to prevent show through and accelerated
wear. Patching compounds must be
suitable for the use application,
polymer-fortified and applied according to
