manual abstract
¦ Commercial kitchens and commercial food processing areas. ¦ Where pointed spikes such as golf or track shoes will be used. ¦ Where the floor will be subjected to unusually concentrated static or dynamic loads. NOTE: Concentrated static and dynamic loads such as hospital beds, roll-out bleachers, portable x-ray machines, etc. may visibly damage resilient as well as other types of floor coverings. For questions regarding product suitability and detailed instructions for floor preparation and installation in these applications, please contact Armstrong. Suitable for Application Over ¦ Concrete, terrazzo, and other dry, structurally sound monolithic subfloors on all grade levels. ¦ Suspended wood subfloor construction with approved wood underlayments, and a minimum of 18 in. (45.7 cm) well- ventilated air space below. ¦ Most metal floors and most existing single-layer resilient floors on approved underlayments. ¦ Radiant-heated subfloors with a maximum surface temperature of 85° F (29° C). Unsuitable for Application Over ¦ Subfloors where excessive moisture or alkali is present. ¦ Sleeper-constructed wood subfloors ¦ Lightweight aggregate concrete subfloors having a density of less than 90 lbs. per cu. ft. (1442 kg/m3) or cellular concrete having a plastic (wet) density less than 100 lbs. per cu. ft. (1602 kg/m3) [94 lbs. per cu. ft. (1506 kg/m3) dry weight] or concrete having a compressive strength of less than 3500 psi (24 MPa). Concrete slabs with heavy static and/or dynamic loads should have higher design strengths and densities calculated to accommodate such loads. Concrete curing agents, sealers, hardeners, or parting agents should be removed. 3. TECHNICAL DATA Shipping Weight 6.0 lbs./sq. yd. (3.3 kg/m2) Gloss (typical value) 60 degrees specular: approximately 5-15 Reference Specifications ASTM F 1303, Type II, Grade 1, Class A backing. Backing is suitable for installation on all grade levels. Static Load Limit ASTM F 970 (modified) 500 lbs./sq. in. (35.16 kg/cm2) ASTM F 970 modified by specifying a higher load on a smaller diameter tip. All other conditions are standard. NOTE: Floors should be protected from sharp-point loads and heavy static loads. High-heeled traffic [1000 psi (70.3 kg/cm2) or more] may visibly damage wood, resilient and other floor coverings. Comparative Subjective Property Ratings Durability: Very Good Maintainability: Excellent Resilience: Very Good Subjective ratings (excellent, very good, good, fair) are in relation to other Armstrong commercial resilient floors. Ratings are not directly related to any one test. They are broadly based on tests and experience of Armstrong Research and Development under varying conditions and circumstances. These ratings should not be used for comparison to ratings used by other manufacturers to rank their own products. Fire Test Data ASTM E 648 Flooring Radiant Panel Critical Radiant Flux – 0.45 watts/cm2 or more, Class I ASTM E 662 Smoke Chamber Specific Optical Smoke Density – 450 or less Numerical flammability ratings alone may not define the performance of the product under actual fire conditions. These ratings are provided only for use in the selection of products to meet the specified limits. 4. INSTALLATION Job Conditions Subfloors/underlayments shall be dry, clean and smooth. They shall be free from paint, varnish, solvents, wax, oil, existing adhesive residue or other foreign matter. For more detailed requirements of concrete, wood and metal subfloors, as well as wood and trowelable underlayments, refer to Armstrong Guaranteed Installation Systems manual, F-5061. Calcium Chloride Tests for moisture must be conducted. Armstrong offers a guideline of a maximum acceptable moisture emission level of 5.0 lbs. per 1000 sq. ft. per 24 hours. Bond Tests should also be conducted for compatibility with the substrate. When testing for alkalinity, the allowable readings for the installation of Armstrong flooring are 5 to 9 on the pH scale. Temperature shall be maintained at a minimum of 65° F (18° C) and a maximum of 100° F (38° C) for 48 hours prior to installation, during installation and 48 hours after completion when using Armstrong S-599 Adhesive. When using Armstrong S-240 Epoxy Adhesive, the temperature shall be maintained at a minimum of 65° F (18° C) and a maximum of 85° F (29° C) for 48 hours prior to installation, during installation and 48 hours after completion. A minimum temperature of 55° F (13° C) shall be maintained thereafter. Condition all flooring materials and adhesives to room temperature at least 48 hours prior to starting installation. Protect all materials from the direct flow of heat from hot-air registers, radiators, or other heating fixtures and appliances. Procedure Connection CORLON must be installed using Armstrong S-599 Adhesive full spread in field areas and Armstrong S-580 Adhesive in flash cove areas. Recess scribe all seams. Seams must be heat-welded or sealed with Armstrong S-761 Seam Adhesive. Connection Corlon...
