Standard Practice for Single Component, Fluid-Applied Membrane-Forming Moisture Mitigation Systems for Use Under Resilient Floor Coverings

Importancia y uso:

4.1 Moisture emitting from concrete substrates can detrimentally affect the performance of resilient floor covering systems. Most resilient flooring and adhesive manufacturers publish a maximum acceptable level of moisture in which their products can perform satisfactorily. Requirements for single component, fluid-applied membrane-forming moisture mitigation systems to be used, and other related details, are generally included as part of the project plans or specifications and may vary from the minimum recommendations set forth in this practice.

4.2 This practice is intended for use by project design teams who have, in advance of bidding and construction, made a decision to include moisture mitigation within the project specifications and bid documents without any requirement for moisture testing of the concrete slabs after they are placed.

4.2.1 This practice is intended for use after it has been determined that a concrete slab moisture condition exceeds the resilient floor covering or adhesive manufacturer’s requirements, or both, as tested according to Test Methods F1869, F2170, or Guide F2659.

4.2.2 This practice is intended for use on normal weight or structural lightweight concrete slab substrate surfaces.

4.3 Single component, fluid-applied membrane-forming moisture mitigation systems are not intended for use over gypsum-based substrates.
