ULTRA STRONG, ULTRA FAST

RAPID FLOOR ULTRA GIVES YOU THE ULTIMATE EDGEFor new construction or renovation, it’s hard to match Rapid Floor® Ultra’s impressive list of application benefits. For reliably superior results, count on Rapid Floor Ultra, one of the strongest gypsum floor underlayments available.

Floor goods go down fast and easy too, over Rapid Floor Ultra’s smooth, hard surface. With proper ventilation, nearly any type of floor covering can be installed within five to seven days of a Rapid Floor Ultra pour. Carpet, vinyl, wood, tile... they’ll all look better and last longer, thanks to Rapid Floor Ultra’s even, flat surface.

Rapid Floor Ultra is considered a “green” building material and meets the stringent requirements of the new GREENGUARD Gold Certification program.

• Cap uneven, rough, cracked or spalled concrete • Level entire floors or transition areas, featheredge to deepfill• Resurface old or damaged concrete floors• Perform up to 4,000 PSI (27.6 MPa)• Resist water absorption• Fill voids in concrete floors• Top corrugated steel deck over light gauge steel framing• Top precast planks• Install right over old floor coverings, including vinyl asbestos tile• Provide fire and sound control over wood frame construction• Requires no troweling • Provide a temporary wear surface just 2–4 hours after application• Exceeds standards set by leading floor goods manufacturers

PREPARATION Building interior should be enclosed and maintained at a temperature above 50 ˚F (10 ˚C) until structure and subfloor temperatures are stabilized. The subfloor must be broom clean and contaminant free. Before pouring Rapid Floor® Ultra, coat the subfloor with a company approved primer.

INSTALLATION METHODS The minimum thickness of Rapid Floor Ultra varies with the type of floor system. Rapid Floor Ultra can be featheredged over concrete substrates. Over wood frame construction, the minimum thickness is 3/4" (19 mm). It can be poured before or after drywall.

Continuous ventilation and adequate heat should be provided to rapidly remove moisture from the area until the underlayment is dry. The general contractor/project superintendent must supply mechanical ventilation and heat if necessary*. Under the above conditions, drying time is usually 5 –7 days. Reference the Building Conditions Guide for complete installation guidelines.

Rapid Floor Ultra requires a floor covering. For detailed instructions on attaching finished floor materials, request the brochure Procedures for Attaching Finished Floor Goods to Maxxon Underlayments. It is the responsibility of the floor goods installer to determine the compatibility of their product with a particular floor underlayment.

LIMITATIONS 1. The typical maximum depth of Rapid Floor Ultra is 3" (76 mm). For depths greater than 3" (76 mm), contact an authorized applicator.2. Rapid Floor Ultra may be scheduled before or after installation of drywall.3. All materials above crawl spaces must be protected by a vapor barrier.4. During construction, place temporary wood planking

over the underlayment wherever it will be subjected to heavy wheeled or concentrated loads.5. Rapid Floor Ultra is not designed to be installed on or below grade, except over well-drained structural substrates.6. Rapid Floor Ultra cannot resist stresses caused by structural movement. 7. The structural subfloor and floor joist must both comply with manufacturers’ maximum span criteria. Typically a deflection limitation of L/360 is adequate for Rapid Floor Ultra. Some floor coverings may require a stiffer floor system. Rapid Floor Ultra is non-structural and therefore cannot be expected to reinforce structurally deficient subfloors. Necessary allowances should be made for expected live, concentrated, impact, and/or dead loads including the weight of finished floor goods and setting beds.8. Additional consideration should be taken for concentrated/dynamic loads. U.S. building codes typically specify a uniform live load of 40 pounds per square foot for residential floor designs. This load is intended to account for large loads that can occur in a building. In reality these loads are not uniform, but rather consist of items such as furniture and appliances that actually induce concentrated loads far exceeding 40 lbs per sq ft. Rolling concentrated loads such as office chairs, wheel chairs, and motorized scooters add turning, twisting, repetition, and other dynamics which should also be taken into consideration. Determining the appropriate structural design of the floor is not the responsibility of Rapid Floor Systems nor the Rapid Floor applicator.9. Due to the unique nature of light gauge steel construction, it may be necessary to pour Rapid Floor Ultra before doors are installed. Contact Rapid Floor Systems for installation details.10. Rapid Floor Ultra should not be used for exterior application, or where it will come into prolonged contact with water.11. Rapid Floor Ultra should not be directly applied to a plastic vapor barrier.12. Rapid Floor Underlayments are “breathable” and not a vapor barrier. The general contractor/project superintendent, architect, specifier, or building owner shall test slabs-on-ground or elevated slabs for MVER (ASTM F1869) or RH (ASTM F2170). If the MVER or RH of the concrete substrate exceeds the floor covering manufacturer’s respective requirements for the finished flooring system, the concrete must be treated with a damp proof membrane, such as Maxxon DPM or Maxxon MVP, before installation of a Rapid Floor Underlayment.ACOUSTICAL PERFORMANCE The acoustical performance of all Rapid Floor products is similar.

*DRYING CONDITIONS Rapid Floor 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 Rapid Floor Underlayments.

The general contractor/project superintendent 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/project superintendent. The general contractor/project superintendent must supply mechanical ventilation and heat if necessary. These controls fall under the scope of work of the general contractor/project superintendent — not Rapid Floor Systems or the Rapid Floor Underlayment installer. See Maxxon's Building Conditions Guide for additional information.

TESTING Compressive strength testing must be performed in accordance with modified ASTM C472. Before independent sampling, contact the Rapid Floor Systems quality control department to ensure that proper procedures are followed.
