Yes, it can be used for sound reduction, crack isolation, waterproofing and vapor management. However, when using Mapesonic 2 for vapor management, do not use MAPEI SM Primer or MAPEI SM Primer Fast; instead, use MAPEI HM Primer. If there are seams, the use of Mapetape BB tape is also be necessary for waterproofing and vapor management.
Yes, with these limitations: Do not use on exterior floors with drainage of less than 1/4" per foot (6 mm per 30 cm). And do not use on shower floors or in submerged applications, or on floors subject to standing water.
Mapeguard UM is approved for exterior applications with some limitations; please consult the Technical Data Sheet for details. Mapeguard UM 35 [NA] is not approved for exterior applications.
ASTM G21 is an industry standard that uses an intensive testing protocol for determining if fungi, including mold and mildew, can grow on a polymeric material. MAPEI uses a third-party lab and the ASTM G21 standard for testing the antifungal effectiveness of MAPEI products containing polymer that incorporate BioBlock technology. The ASTM G21 test uses a mix of mold and mildew spores commonly found in household environments. Product samples are placed on nutrient-containing plates and sprayed with a mixture of these fungi. For 28 days, the test plates are kept at a constant temperature of 84.2°F (29°C) and exposed to high humidity, which are excellent conditions for fungal growth. The samples are then examined for fungal growth. If no growth is present, the product is considered to not support mold/mildew/fungal growth.
Products identified with MAPEI's BioBlock logo have been developed in such a way that they do not support mold/mildew/fungi growth after product installation as certified by external laboratories per industry standard ASTM G21: Standard Practice for Determining Resistance of Synthetic Polymeric Materials to Fungi. Common cleaning and maintenance practices are still needed.
Yes, with these limitations: Use MAPEI adhesive Ultrabond ECO 350, Ultrabond ECO 360, Ultrabond ECO 373 or Ultrabond ECO 399. Also, follow MAPEI’s Technical Data Sheet instructions and use a 1/32" (1 mm) U-notch trowel. Finally, expect 60 to 90 minutes of flash time before installing the LVP/LVT.
