SOUND REDUCING LIQUID UNDERLAYMENT
PATCH AND LEVELER
SPECIFICATION SHEET
DESCRIPTION: Taylor Acous-Tec® Sound Reducing Liquid Underlayment Patch and Leveler is designed for all floating floor systems
(vinyl tile/plank, laminate, and wood) to reduce sound transmission (up to IIC 71 and STC 67). Acous-Tec also controls moisture levels,
patches up to 1/8" cracks, levels substrate unevenness, and enhances thermal insulating properties of the floor. It is an excellent
replacement for rolled sound reducing membranes with its easy installation, one hour set-up time and when fully cured it is a sealed,
leveled, and flat membrane. Requirements for installing underlayment are simple; it is unaffected by concrete slab alkalinity, can be
installed on porous or non-porous surfaces, and has extremely low permeability ratings. As the product cures it uses it’s formulated
cross-linking modified silane polymer-base to build a tenacious but elastic resilient membrane.
Taylor Acous-Tec is free of solvents, hazardous chemicals (per OSHA Regulation CFR 1910.1200), water, and isocyanates. This
product is a one component, 100% solids, non-flammable and low odor liquid underlayment with negligible VOC content that meets
federal, state, and local governmental indoor air quality regulations; achieving the coveted UL’s GREENGUARD Certification.
USE OVER: Taylor Acous-Tec Sound Reducing Liquid Underlayment Patch and Leveler may be used over APA grade underlayment
plywood, flooring grade particleboard, OSB, cork underlayment, existing well bonded non-cushioned resilient flooring, terrazzo,
cementitious and anhydrite screeds, concrete, and radiant heated subfloors where surface temperatures do not exceed 85°F (30°C).
Install above, on, or below grade, in the absence of excessive moisture. While this barrier is waterproof when cured, the installation still
must be protected from excessive moisture. Moisture levels of concrete must be below 10 lb/1000 sq. ft./24 hr per ASTM F-1869 test
method & relative humidity (RH) 90% per ASTM F-2170. When installing Acous-Tec™ use a 1/16" x 3/32" saw tooth trowel, or 3/16" x
5/32" saw tooth trowel for patching or self-leveling, for all installations. The moisture content must be within the flooring manufacturer’s
guidelines for allowable levels of moisture.
SUBSTRATE PREPARATION: Substrate must be sound, smooth, clean, level, dry, and free of dust, dirt, grease, oil, paint, curing
compounds, incompatible sealers, fire retardant chemicals, release agents, or any other foreign substance that might interfere with a
good bond. Subfloor must be smooth and fully adhered. Depending on the type and condition of the subfloor, mechanical treatment of
the subfloor such as mechanical brushing, grinding with coarse sand paper, milling or ball blasting may be required. It is the sole
responsibility of the installer/contractor to ensure that the concrete surface is properly prepared prior to installation.
INSTALLATION: Acous-Tec Sound Reducing Liquid Underlayment, the floor covering and areas to receive flooring must be maintained
at a temperature of 65° - 95°F (18° - 35°C) and at a relative humidity of 30% - 60% for 72 hours before, during, and after installation.
Follow the flooring manufacturer’s guidelines regarding site conditions, layout, and installation.
Apply Acous-Tec Sound Reducing Liquid Underlayment Patch and Leveler with the recommended trowel and allow to dry and cure for
approximately one hour; however, Acous-Tec™ underlayment must be dried and cured throughout the film thickness before installing
the floating floor system. The drying time will vary with ambient job site conditions. Always follow the flooring manufacturer’s installation
guidelines for their floating floor systems.
NOTE: When using the 3/16" x 5/32" saw tooth trowel for patching and self-leveling, Acous-Tec may require more cure time. Damp
mopping the floor prior to application can speed up cure time. Follow all other instructions for floor preparation.
CLEAN UP:
Use a solvent based adhesive remover/stripper that is compatible with the flooring manufacturer's finish.
TROWEL RECOMMENDATIONS
APPLICATION
SQ. FT. / GALLON
TROWELS
*For sound reducing underlayment,
moisture barrier, and filling cracks:
Up to 100 sq. feet per gallon
(2.5 sq. meters per liter)
1/16" x 3/32" Saw Tooth
(1.6mm x 2.4mm)
For sound reducing underlayment, moisture
barrier, filling cracks, patching and leveling:
Up to 60 sq. feet per gallon
(1.5 sq. meters per liter)
3/16" x 5/32" saw tooth
(4.8mm x 4.0mm)
NOTE: Liquid underlayment coverage is approximate and will vary depending on the porosity and roughness of
subfloor, angle at which the trowel is held, temperature or the liquid underlayment and subfloor, and the skill of the
installer applying the liquid underlayment. The liquid underlayment coverage will be improved by priming the subfloor
to reduce absorption of the liquid underlayment into the subfloor. The underlayment coverage will be significantly
lower over subfloors not properly prepared according to established industry guidelines.
