OLD CONCRETE
covering, all traces of old adhesives, paint, or other contaminants by
scraping, sanding, grinding, shot-blasting or scarifying the substrate.
The use of adhesive removers or solvents in the abatement or
removal of existing or old adhesives is prohibited and may void
the LVT warranty.
WARNING: ASBESTOS & SILICA – Refer to the current Resilient
Floor Covering Institute (RFCI) document “Recommended Work
Practices for Removal of Existing Resilient Floor Coverings” for
guidance.
POWER-TROWELED CONCRETE
Power-troweled concrete surfaces can be very slick, relatively non-
absorbent, and may produce surface laitance. These conditions can
perform bond tests to determine suitability.
Lightweight Concrete: The minimum density of lightweight concrete
should be greater than 90lbs. per cubic foot, with minimum compression
strength of 2,500 psi or greater. Perform only In-Situ Relative Humidity
(RH) test in strict accordance to the latest edition of ASTM F2170.
Existing lightweight concrete or gypsum substrates may need to
Preparation manufacturer for recommendations, and always perform a
bond test before proceeding. You can also contact Customer Service.
In-Floor Heating: Radiant heating systems must be cast ½" below the
surface of the concrete slab, and should be operating at least 2 weeks
system to 68°F 48 hours before, at all times during, and 72 hours after
increased 72 hours after installation, but the surface temperature should
never exceed 85°F. Contact the manufacturer of your radiant heating
system for further recommendations.
MOISTURE MITIGATION
moisture tolerances). Due to the complexities associated with concrete
moisture vapor emissions and movement of soluble salts in concrete
meet the criteria listed in ASTM F3010 (Standard Practice for Two-
Component Resin Based Membrane-Forming Moisture Mitigation
Systems for Use Under Resilient Floor Coverings) are recommended.
WOOD SUBFLOORS
GENERAL CONDITIONS
minimum ¼" (6mm) thick, APA-rated “underlayment grade” plywood
with a fully sanded face, or other underlayment panel that is appropriate
radius, and should not slope more than 1" per 6 ft. in any direction, with
a minimum 18" (45cm) of well- ventilated air space underneath. Crawl
spaces should be insulated and protected by a vapor barrier. Do not
is in direct contact with a concrete slab. All wood substrates must meet
and underlayment panels using a suitable wood-moisture meter. The
maximum moisture content is 14%, and the readings between the
the underlayment panels.
UNDERLAYMENT PANELS:
• Structurally sound
• A minimum of ¼" (6mm) thick
• Of a smooth surface, so as to prevent telegraphing
• Able to resist indentations
Plywood: Use only American Plywood Association (APA) rated
underlayment grade plywood, with a minimum grade of “BB” or “CC”,
and minimum ¼" thickness. Allow expansion spacing between plywood
installing underlayment, stagger cross-joints 4' on an 8' panel (minimum
the surface level of the underlayment. Fill underlayment seams, nail
holes, and any indentations with an approved Portland Cement-type
plywood underlayment, with a fully sanded face and exterior glue. All
dust must be COMPLETELY removed to ensure a strong adhesive
bond. Vacuum or sweep thoroughly, then apply adhesive.
Lauan Plywood: Use only Type 1 lauan exterior grade “BB” or
“CC” for underlayment. The use of lesser grades of lauan plywood
is unacceptable, and may cause severe problems when used as an
underlayment, including: discoloration, indentation, loss of bond, and
delamination.
NOTE: The use of lauan plywood and other extremely porous
adhesives. It is best to apply an acrylic-based primer-sealer to
any porous substrate prior to installing LVT. A manufacturer’s
the use of a lauan underlayment.
