SAM 125 (3.2 mm) SOUND ABATEMENT MEMBRANE
Sound Rated Ceiling Assembly Required
Super SAM 125 (Sound Abatement Mat) System, membrane and
primer, provides three functions. It is a sound reduction
membrane, a crack suppression membrane and a waterproof
membrane when used with an approved sealant, all in one
easy-to-use roll. Recommended for light commercial and residential
Super SAM 125 System is a 125 mil, self-adhering, sound
deadening sheet membrane for use over 6" or 8"
concrete slabs without a sound rated ceiling assembly. It
is chemically formulated to reduce airborne (STC) and impact
(IIC) sound transmission when used under stone, ceramic
and porcelain tile, wood and commercial grade vinyl tile.
The Super SAM System is composed of modified elastomers,
sound deadening resins and reinforced woven fibers. Super
SAM self-adhering composition produces a quick and economical
installation over 6" and 8" concrete slabs without
sound rated ceiling assemblies.

Super SAM 125 System is designed for floors requiring an
Impact Insulation Class (IIC) rating not less than 50 and
a Sound Transmission Class (STC) rating of not less than
50, as determined by ASTM Standards E90, E413 and E492.
Assemble to meet or exceed tile industry standards.
Medium bed installation of ceramic tile products, stone,
pavers, or brick requiring sound abatement such as: apartments,
condominiums, multi-level hotels, high-rise office buildings,
media rooms, children play areas and other areas needing
sound reduction. Other finished floors may be acceptable,
check with manufacturer. Super SAM 125 can be applied interior
and exterior over:
Concrete: Poured, pre-stressed and pre-cast concrete cured
at least 28 days. Concrete backerboard, mud beds, concrete
block, gypsum, light weight concrete, patching compounds
and radiant heated / warm floors. Wood: Exterior or exposure
1 plywood, APA-rated sheathing, Sturd-I-Floor, hardwood,
tongue and groove and OSB with standard face. (Gap between
sheeting as required.) Other Substrates: Ceramic and porcelain
tile, stone, terrazzo, VCT/VAT, metal, painted and sealed
floors and floors damaged by dry shrinkage and structural
Black Mat MVT (Moisture Vapor Transmission) test to determine
if MVT is present. If
MVT is present, conduct F-1869-98 test for Moisture Vapor
Emissions. Vapor drive should not exceed 10#/thousand
square feet in 24-hours.
• For absorptive surfaces, apply one coat of 101
Floor Prep. Let cure 3 to 4 hours or overnight before
• For concrete block, a cementitious parge coat
must be applied to concrete block and cured before priming.
• Substrates must be dry, well adhered, clean of
wax, petroleum, sealers, dirt, grease, oil or other inhibitors.
Some concrete boards are not suitable for the application
of Super SAM 125; check with the manufacturer
