1 SECTION GYPSUM CEMENTITIOUS UNDERLAYMENT PART 1 GENERAL 1.01 SUMMARY A. This is the recommended specification for Gyp-Crete Floor Underlayment. A. Gyp-Crete gypsum cement B. Maxxon Floor Primer C. Maxxon Overspray 1.03 QUALITY ASSURANCE A. Installer's Qualifications: Installation of Gyp-Crete shall be by an applicator authorized by the Maxxon Corporation using Maxxon approved mixing and pumping equipment DELIVERY, STORAGE AND HANDLING A. General Requirements: Materials shall be delivered in their original, unopened packages, and protected from exposure to the elements. Damaged or deteriorated materials shall be removed from the premises SITE CONDITIONS A. Environmental Requirements: Before, during and after installation of Gyp-Crete, building interior shall be enclosed and maintained at a temperature above 50 degrees F (10 degrees C). PART 2 PRODUCTS 2.01 MATERIALS A. Gypsum Cement: Floor underlayment Gyp-Crete gypsum cement as manufactured by the Maxxon Corporation, Hamel, MN. All others must receive prior approval. B. Sand Aggregate: Sand shall be 1/8 inch (3 mm) or less, washed masonry or plaster sand, meeting requirements of Maxxon Corporation Sand Specifications 101. C. Mix Water: Potable, free from impurities. D. Subfloor Primer: Maxxon Floor Primer E. Sealer: Maxxon Overspray 2.02 MIX DESIGNS A.

2 PART 3 EXECUTION 3.01 PREPARATION A. Condition and Cleaning of Subfloor: Subfloor shall be structurally sound. General Contractor shall clean subfloor to remove mud, oil, grease, and other contaminating factors before the arrival of the Gyp-Crete underlayment crew. B. Leak Prevention: Fill cracks and voids with a quick setting patching or caulking material where leakage of Gyp-Crete could occur. C. Priming Subfloor: Prime the subfloor using the Maxxon Floor Primer. Priming instructions may vary according to the type of substrate, multiple coats may be necessary. D. Expansion Joints: Allow joints to continue through the Gyp-Crete at the same width APPLICATION OF CEMENTITIOUS FLOORING A. Scheduling: Application of Gyp-Crete shall not begin until the building is enclosed, including roof, windows, doors and other fenestration. Install after drywall installation unless tenant finish requirements identify partitioning after the pour. B. Application: Place Gyp-Crete at 3/4 inch (19 mm) minimum over wood frame, 1/2 inch (13 mm) minimum over plank or poured in place concrete. Spread and screed Gyp-Crete to a smooth surface. Except at authorized joints, place Gyp-Crete as continuously as possible until application is complete so that no Gyp- Crete product slurry is placed against Gyp-Crete product that has obtained its initial set. C. Drying: General Contractor shall provide continuous ventilation and adequate heat to rapidly remove moisture from the area until the Gyp-Crete is dry. General Contractor shall provide mechanical ventilation if necessary. Under the above conditions, for 3/4 inch (19 mm) thick i. Gyp-Crete, 5-7 days is usually adequate drying time. To test for dryness, tape a 24 inch by 24 inch (609 mm by 609 mm) section of plastic or high density rubber mat to the surface of the underlayment. After hours, if no condensation occurs, the underlayment shall be considered dry. Perform dryness test 5-7 days after pour PREPARATION FOR INSTALLATION OF GLUE DOWN FLOOR GOODS A. Sealing: Seal all areas that receive glue down floor goods with Maxxon Overspray according to the Maxxon Corporation's specifications. Any floor areas where the surface has been damaged shall be cleaned and sealed regardless of floor covering to be used. Where floor goods manufacturers require special adhesive or installation systems, their requirements supersede these recommendations. B. Floor Goods Procedures: See the Maxxon Corporation's "Procedures for Attaching Finished Floor Goods to Maxxon Underlayments" brochure for guidelines for installing finished floor goods. This procedure is not a warranty and is to be used as a guideline only FIELD QUALITY CONTROL Elderly Apartment

3 A. Slump Test: Gyp-Crete mix shall be tested for slump as it's being pumped using a 2 inch by 4 inch (50 mm by 101 mm) cylinder resulting in a patty size of 8 inches (203 mm) plus or minus 1 inch (25 mm) diameter. B. Field Samples: At least one set of 3 molded cube samples shall be taken from each day's pour during the Gyp-Crete application. Cubes shall be tested as recommended by the Maxxon Corporation in accordance with modified ASTM C 472. Test results shall be available to architect and/or contractor upon request from applicator PROTECTION A. Protection From Heavy Loads: During construction, place temporary wood planking over Gyp-Crete wherever it will be subject to heavy wheeled or concentrated loads. END OF SECTION Elderly Apartment
