Since gypsum first met sand in 1972, Gyp-Crete, now Maxxon® Corporation, has provided superior underlayment products for solving virtually any floor problem. Maxxon not only started the industry, but continues to lead it with high quality products, training, research and expert installation by a nationwide network of authorized dealers.
Proven on over 3.5 Billion Square Feet.
Where will you find Maxxon® underlayments at work?
Enhancing sound control in multifamily dwellings. Efficiently warming commercial buildings and homes with radiant floor heat. Providing a level surface on otherwise out-of-level concrete slabs. And giving new life to floors that were once damaged beyond repair. Whatever the challenge, count on answers specific to your application from Maxxon – the floor specialists. From the original Gyp-Crete® Floor Underlayment, the Maxxon line has expanded to include five gypsum floor underlayments and cementitious underlayments. Each is designed to solve a particular construction problem – and proven in over 4.5 billion square feet of underlayments installed in apartments, commercial buildings and homes worldwide. Maxxon's underlayments are GREENGUARD Indoor Air Quality Certified® with some earning the GREENGUARD Children and School CertificationSM the most stringent product emission criteria in the market.
Maxxon Floor Underlayments are specified in all the best sound control systems because they...
- Seal perimeter cracks, reducing sound leaks
- Stiffen the floor, virtually eliminating squeaky floors and nail pops
- Muffle sound transmission, despite their light weight (see Sound Ratings table in "Specifications and Sound Ratings" Profile)
For the most advanced sound and fire control, Acousti-Mat® sound control systems are the answer. With a nylon core of fused entangle filaments attached to a non-woven fabric, Acousti-Mat creates a void area between the subfloor and the high-strength underlayment. This actually isolates sound waves, reducing airborne and impact noise. Acousti-Mat II, Acousti-Mat 3, Acousti-Mat LPR and Enkasonic are made with 40% recycled nylon. Acousti-Mat II, Acousti-Mat 3 and Enkasonic are GREENGUARD Children and Schools Certified.
In wood frame construction, Maxxon Floor Underlayments provide a flame barrier between combustible materials. Over precast concrete they can increase UL fire ratings by two hours. And because our products flow under the drywall, they seal each room, fighting the spread of fire. See "Fire Tested Assemblies" Profiles in this program.
Efficient Application and Fast Drying Time Keep You on Schedule.
We know the construction business operates on a tight schedule, so Maxxon applicators use specially designed equipment that can pump 1,000 to 40,000 square feet (92.9 m2 – 3,716 m2 ) of product in a single day.
Besides fast application, you can walk on any Maxxon underlayment within 90 minutes. That's strength. By the next day, the job is ready for painters and other light subtrades. Plus, tests show that Maxxon gypsum underlayments retain their strength when re-dried in water for 30 days.*
*Gyp-Crete Performance Test, Tetco Report #9-018
Maxxon underlayments can turn a rough, irregular surface into one that's perfect for carpet, wood, ceramic tile, vinyl…virtually any floor covering. Our Procedures Brochure outlines how each one can be installed flat and smooth.
Compared to old-fashioned underlayments, it's easy to see why Maxxon underlayments are so popular.
- No harmful urea formaldehyde
- Won't delaminate
- Won't shrink crack
- No squeaks or nail pops
At Maxxon® we stress quality in our products and service. We start with a program that attracts only the most qualified applicators, and we continually monitor their performance through quality audits, product sampling and compressive-strength testing. We also have a nationwide system of rewards that recognizes outstanding work and superior service, and we regularly hold technical seminars to update applicators on new methods.
That's why Maxxon® manufactures several underlayments – gypsum, and cementitious. While each is designed to accomplish a specific task, all of them are...
- Designed for use as a non-wearing, interior floor underlayment
- Installed on the job site by authorized dealers, each trained by and experienced in proper application techniques
- Formulated to create a smooth surface, ready for finished floor goods.
Dura-Cap®, Commercial Topping and Gyp-Crete 2000®/3.2K
take worn, uneven floors and make them flat and smooth. Poured from a featheredge
to three inches deep, they fill cracks and voids left after walls are removed.
Perfect for renovations over wood, concrete and old floor coverings.
Dura-Cap or Commercial Topping Floor Underlayment
make any irregular or damaged concrete floor like new. They can spot-patch depressions
or smooth an entire floor. Plus they attain compressive strengths of up to 4,500
psi (31.7 MPa). And as levelers, Dura-Cap and Commercial Toppingare
easily poured in small and large jobs alike. For new wood-frame commercial buildings,
Gyp-Crete 2000 provides a strong underlayment.
Builders appreciate Gyp-Crete 2000 because
it won't warp or delaminate like plywood, and it helps eliminate squeaks
and nail pops. Homeowners like Gyp-Crete 2000 because it makes their homes
more energy efficient, fire resistant and comfortable. And because it seals
the base of every room, it helps keep out insects and other pests. For
homeowners who opt for radiant floor heating, Therma-Floor® is the
underlayment of choice. It provides all the benefits of Gyp-Crete 2000,
plus special additives to meet the demands of this increasingly popular
heating system.
Sound and fire control are the primary
reasons for specifying Gyp-Crete® in multifamily designs, but general
contractors also prefer our underlayments for their quick installation,
fast drying and minimum preparation requirements. Gyp-Crete 2000, Dura-Cap
and Commercial Topping are the higher strength, faster drying choices for
areas that will receive glue-down floor goods. A six person crew can pour
30,000 square feet (2,787 m2) in a single day. And with our
fast setting time, painters and other light subtrades can be scheduled
within 24 hours.
When the job calls for a high-strength,
self-leveling, cementitious underlayment, Level-Right® is the cost-effective
solution. It’s pumped in directly over new, irregular or weather-damaged
concrete, wood, or over worn ceramic tile, terrazzo and adhesives—making
them smooth and level. Level-Right saves time and money in prepping
floors for floor goods installation, too.
Maxxon® underlayments
are for interior use only and should not be poured directly over a plastic vapor barrier. Before, during and after installation,
building interior shall be enclosed and maintained at a temperature above
50ºF (10ºC).
The wood or concrete subfloor shall be
structurally sound, broom clean and contaminant free. The subfloor must
be adequate to withstand live and dead loads with a deflection limitation. Before installation, general contractor shall inspect the wood
floor for proper nailing. Any wood weakened or delaminated during construction
shall be replaced. Stud wall baseplates in doorways and other openings
are to be removed.
The minimum thickness varies with the
type of floor system. Gyp-Crete is to be poured after the drywall
is
installed. Gyp-Crete 2000 may be poured before or after drywall installation.
- Minimum wood frame construction is agency-approved
19/32" (15 mm), 40/20 veneer and non-veneer wood subfloors.
- Preferred wood frame construction is 3/4"
(19 mm) of underlayment over 3/4" (19 mm) tongue-and-groove, agency-approved
subfloor with truss, joist or beam spacings of 16" to 24" (406 mm - 609
mm) on-center.
- Over concrete, the minimum thickness of
Gyp-Crete is 1/2" (13 mm). For Gyp-Crete 2000, the minimum thickness is
usually 1/2" (13 mm). However, the 1.4 mix design can be featheredged.
Over concrete, the minimum thickness is
usually 3/8" (10 mm). However, the 1.4 mix design can be featheredged.
Over wood frame construction, the minimum thickness is 3/4" (19 mm). It
can be poured before or after drywall.
The thickness of Therma-Floor varies with the type
of radiant floor heating system. Therma-Floor
is to be poured to a depth that is 3/4" (19 mm) above the top of the tubes or
cables. Therma-Floor can be poured before or after drywall is installed.
Concrete subfloors must be fully cured,
moisture free and have no efflorescence. The substrate surface shall be
clean, dust and contaminant free. Cracks should be filled with a
crack filler or an elastomeric compound. Plumbing or electrical penetrations
should be packed with insulation and sealed.
Before, during and after installation of a Maxxon® underlayment, building
interior shall be enclosed and maintained at a temperature above 50 ºF (10
ºC) until structure and subfloor temperatures are stabilized.
Maxxon gypsum underlayments are inorganic and provide no source of nutrients
to sustain mold growth. Prolonged contact of moisture with other construction
materials, however, can result in mold growth. To avoid growth of mold on construction
materials such as wallboard, drywall compound and even dust, it is vital to maintain
a low relative humidity both before and after placement of Maxxon gypsum underlayments.
The general contractor must provide and maintain correct environmental conditions
to keep the building clean and dry, and protect against infestation of moisture
from a variety of potential sources. Moisture can be introduced by other trades
through spillage, tracked in mud and rain, plumbing leaks, etc. Often stored in
damp conditions, building products may arrive on site laden with moisture that
releases after installation. Outside sources such as rain, snow, wind, etc. can
also increase moisture levels.
Controlling moisture levels in the building, through appropriate trade sequencing
and prevention of potential damage by other trades, is the responsibility of the
general contractor. The general contractor must supply mechanical ventilation
and heat if necessary. These controls fall under the scope of work of the general
contractor — not Maxxon Corporation or the Maxxon underlayment installer.
For gypsum underlayments, compressive strength testing
must be performed in accordance with modified ASTM C 472. For Level-Right®,
Level-Right® PLUS, or Level-Right® FS-10, field testing must be performed in
accordance with modified ASTM C 109. Before independent sampling, contact the
Maxxon quality control department to ensure that the proper procedures are followed.
Maxxon® Corporation has
performed over 60 different sound tests on Maxxon Gypsum Cement Underlayments.
Each was performed by recognized testing agencies over a wide variety of floor/ceiling
assemblies. All tests had sound ratings above the minimum values accepted by major
housing codes. The acoustical performance of Gyp-Crete®,
Gyp-Crete 2000®, Therma-Floor®, Dura-Cap®
and Commercial Topping®
are all similar. See the Sound Ratings table in this Profile.
During construction, general contractor
must place temporary wood planking over underlayment wherever it will be
subjected to heavy wheeled or concentrated loadings. Maxxon underlayments
are not to be used on or below grade, except over well-drained structural
substrates. They should also not be used in areas that have prolonged contact
with water. The typical maximum depth for gypsum underlayments is 3" (76
mm). For depths greater than 3" (76 mm), contact your Maxxon dealer.
