15、nited States14. Significance and Use4.1 Moisture permeating from concrete substrates can det-rimentally affect the performance of resilient floor coveringsystems.All resilient flooring and adhesive manufacturers havea maximum acceptable level of moisture in which theirproducts can perform satisfacto
16、rily. If pre-installation moisturetests indicate that the moisture level is unacceptable for thespecified floor covering to be installed, one option is to applya topical treatment to the concrete substrate surface to mitigatethe moisture condition. Experience has shown that certaintypes of membrane-
17、forming moisture mitigation systems havemore desirable properties and successful performance thanothers. Requirements for membrane-forming moisture mitiga-tion systems to be used, and other related details, are generallyincluded as part of the project plans, or specification details,and may vary fro
18、m the minimum recommendations set forth inthis practice.4.2 This practice is intended for use after it has beendetermined that a floor moisture condition exceeds the resilientfloor covering or adhesive manufacturers requirements, orboth, as tested according to Test Methods F1869, F2170, andF2420.4.3
19、 Membrane-forming moisture mitigation systems are notintended for use over gypsum-based substrates or other mois-ture sensitive substrates.5. Product Requirements5.1 The membrane-forming moisture mitigation systemshall be a two-component resin based product.5.2 Membrane-forming moisture mitigation s
