Performance Core T&G Installation Instructions 020818
Direct Glue Installation: Make sure the floor covering materials are well bonded to the sub-
floor/underlayment with full spread adhesive and no more than two layers thick, not to exceed 3/16″
(5 mm). With approved wood/wood composite sub-floors, if vinyl or tiles are loose, broken, or in poor
condition, install a 3/8″ (9.5 mm) approved sub-floor panel directly over the flooring materials. Clean
the flooring materials as necessary to remove waxes, sealers or cleaning residues to allow a good
adhesive bond. Cork floor sealers and surface treatments must be removed. Always perform a bond
test prior to beginning direct glue installation.
Before You Start
Adhesive Selection:
Acceptable sub-floor moisture condition requirements will vary dependent upon your selection of
M1000, M808 or M908/WUA2 adhesive. Adhesive moisture requirements are not interchangeable
between adhesives and vary dependent upon the sub-floor type and conditions. The sub-floor
moisture requirement and test for each adhesive is outlined in the following:
M1000 ULTRATACK ADVANCED 3 IN 1 ADHESIVE (CONCRETE ONLY):
 Up to 95% RH Levels in Concrete Using In-situ Probes in accordance with the latest version
of ASTM F 2170.
• A pH test up to 11.0.
• Test for sealers and curing compounds.
M808 TRI-POLYMER ADHESIVE (WOOD & CONCRETE SUB-FLOOR):
Wood:
• Wood substrates should test less than 12% using a wood moisture meter.
Concrete:
• Up to 85% RH Levels in Concrete Using In-situ Probes in accordance with the latest version
of ASTM F 2170.
• pH test results must be between 7.0 - 9.0.
• Test for sealers and curing compounds.
M908/WUA2 PRO-TACK URETHANE ADHESIVE:
Wood:
 Wood substrates should test less than 12% using a wood moisture meter.
Concrete:
• Less than 3 lbs/1000 sq. ft./24 hrs. Calcium Chloride Test (ASTM F1869)
• Up to 75% RH Levels in Concrete Using In-situ Probes in accordance with the latest version
of ASTM F 2170.
• Test for sealers and curing compounds
To correct any sub-floor conditions concerning moisture, either wait until the sub- floor dries
to meet specifications or use an appropriate moisture barrier. For more information
concerning moisture conditions, contact Technical Service Department at 888-387-9881
Option 3.
DO NOT INSTALL FLOORING IF MOISTURE TESTS RESULTS EXCEED RECOMMENDED
LIMITS.
• Plan your layout and determine the direction of the installation in the room. Planks installed parallel
to windows accent the hardwood best.
• Blending of Cartons: To achieve a uniform installation appearance, preselect and set aside
hardwood planks that blend best with all trims and moldings. Install these planks next to best
blended moldings.
• Remove all wall mounted moldings such as base and quarter round.
• Floor should be installed blending planks from several cartons to ensure good color and shade
mixture throughout the installation.
• Be attentive to staggering the ends of the boards at least 6″ (10-15 cm), in adjacent rows.
NOTE: USE OF A RUBBER MALLET TO INSTALL FLOORING IS NOT RECOMMENDED AS
STRIKING THE SURFACE WITH A RUBBER MALLET MAY CAUSE IRREPARABLE DAMAGE
TO THE PLANK.
GLUE DOWN INSTALLATION GUIDELINES
Select adhesive based on Adhesive Selection Guidelines provided above.
CONCRETE: If an excess sub-floor moisture situation exists, it is required that M1000 Ultratack
Advanced 3 in 1 Adhesive be applied using the provided clip-on trowel. Use of these or products with
equal or greater specifications are necessary for warranty compliance.
Engineered Flooring – Moisture/Sound Suppression
Method Application (trowel clip on top of bucket):
M1000 Ultratack Advanced 3 in 1 Adhesive
A low VOC saline terminated polymer adhesive designed for use on or above grade concrete
substrates where excessive moisture may be present.
For concrete substrates with RH readings up to 95% use the Clip-On Trowel Blade provided and
attached to the top of each pail. Clip on trowel blade must be replaced with each pail of adhesive
used or more frequently as wear dictates. Floor pH must not exceed 11. ------ Approximate
coverage 35 square ft. per gallon.
For concrete substrates with RH readings less than 80% use a 3/16” x ¼” x ½” Flat V Notch Trowel.
Trowel should be replaced every 3000 square feet or sooner if excessively worn. Floor pH must not
exceed 11. ------ Approximate coverage 55 square ft. per gallon.
*Coverage is based on application to a clean, smooth concrete substrate; therefore, application rate
may vary depending on substrate conditions.
USES:
▪ For protection from concrete moisture up to 95% RH
▪ Sound reduction in multi-story buildings
▪ Crack suppression for in plane cracks up to 1/8” wide
Important: Only the above specified trowels and application methods are to be used with this
adhesive; otherwise, the product performance warranties and liabilities will be made void.
Use of these or products with equal or greater specifications are necessary for warranty
compliance.
M808 Tri-Polymer Adhesive:
A high tri-polymer formula adhesive for the installation of engineered wood flooring over a variety
of properly prepared substrates including: concrete, APA approved sub-floor panels, sheet vinyl,
VCT and clean abraded terrazzo.
Wood substrates should test less than 12% using a pin moisture meter.
Use a 3/16” x ¼” x ½” Flat V Notch Trowel. Trowel should be replaced every 3000 square feet or
sooner as wear dictates. ------ Approximate coverage is 200-220 square ft. per 4 gallons.
Concrete substrates should test less than 85% RH use a 3/16” x ¼” x ½” Flat V Notch Trowel.
Trowel should be replaced every 3000 square feet or sooner as wear dictates. ------ Approximate
coverage is 200-220 square ft per 4 gallons.
*Coverage is based on application to a clean, smooth concrete substrate; therefore, application
rate may vary depending on substrate conditions
USES:
▪ For protection from concrete moisture up to 85% RH
▪ Will not etch the finish on a pre-finished board
▪ May be used on properly prepared concrete or wood substrates.
Important: Only the above specified trowels and application methods are to be used with
this adhesive; otherwise, the product performance warranties and liabilities will be made
void.
