12、oats, slip resistance, and joint work.Edit this guide specification for project specific requirements by adding, deleting, or revising text. For bracketed items, choose applicable items(s) or insert appropriate information.Remove information and requirements not required in respective project, wheth

A listing of Technical Proponents, including their organization designation and telephone number, is on the Internet.Recommended cha
14、nges to a UFGS should be submitted as a Criteria Change Request (CCR).*NOTE: The epoxy mortar flooring system is appropriate for use in: aircraft maintenance hangars, equipment maintenance shops, jet engine test cells, and all other industrial floors where resistance to impact, abrasion, and fuel is
15、 required. Installation costs: $5.00 to $10.00 per 0.1 square meters square foot. Nominal thickness: 6.25 mm 1/4 inch. Benefits: Tolerates high Moisture Vapor Emission (MVE) rates, produces a level surface over coarse concrete, high impact resistance, good chemical resistance, and may provide a suit
16、able topcoat base for more than 10 years service. Can be rejuvenated by replacing urethane topcoats, and SECTION 09 67 23.16 Page 3Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-non-skid, only. Approximate service life: Urethane topcoating with non-
17、skid grit at three or more years. The flooring system is neither conductive nor Electro-Static Dissipative (ESD), however, either formulation is easily designed upon request. This specification is not for use in overcoating existing sound coating systems.*NOTE: Prior to the flooring systems installa
18、tion, a concrete condition assessment in accordance with the Naval Facilities Engineering Service Centers (NFESC) Users Guide (UG)-2036-SHR is highly recommended. The condition assessment is designed to identify problem floors and eliminate premature flooring failures produced by: 1) Coating concret
19、e with low surface strength, 2) coating concrete with high surface contamination levels (oils, fuels, fats, waxes, etc.), and 3) coating concrete with a high Moisture Vapor Emission (MVE) rate. The thin film flooring system is suitable for application to: A) “Smooth“ or “Coarse“ concrete surface tex
20、tures, B) concrete with a MVE rate no more than 254 micrograms moisture per second, square meter 4.5 pounds moisture per 24 hours, 1000 square feet (ASTM F 1869), C) concrete with surface strength greater than 1.34 MPa 200 psi (ASTM D 4541), and D) concrete with fuel/oil contamination to a depth no
21、more than 6.25 mm 1/4 inch.*NOTE: If a concrete floor has a Moisture Vapor Emission (MVE) rate more than 254 micrograms moisture per second, square meter 4.5 pounds moisture per 24 hours, 1000 square feet (ASTM F 1869), apply a layered Moisture Reducing System (MRS) prior to the epoxy mortar floorin
22、g system application. Use MRS compatible with the submitted flooring system and approved / warranted by the epoxy mortar flooring system manufacturer. Apply the MRS to shot blasted concrete and reduce the MVE rate to less than 254 micrograms moisture per second, square meter 4.5 pounds moisture per
23、24 hours, 1000 square feet. MRSs can employ combinations of concrete sealers, specific epoxies, and moisture insensitive grouts, with or without mesh. MRSs are available from the following partial list of epoxy mortar flooring system vendors: Tennant (800) 553-8033, Stonhard (856) 779-7500, General
