Moisture Mitigation


MS-225: Moisture Barrier

PROFLEX® MS-225 Moisture Sealer is a unique one-part, multi-functional moisture barrier that dries to a clear film that is alkali and water-resistant. It is designed for use on interior porous concrete substrates as a penetrating and film-forming hydrophobic (water repelling) barrier to protect flooring installations against moisture vapor transmission rates of up to 15 lbs. Per 1000 sq. ft. per 24 hours and in-situ Relative Humidity (RH) moisture readings up to 95%. The multi-functionality of the product results from the barrier coating ability to prime porous concrete and eliminate dust, and to neutralize surface alkalinity by forming a barrier coating that provides an acceptable pH level and block migration of alkaline salts through the slab.)

Advantages

  • Reduces Moisture vapor transmission up to 15lbs or 95% RH
  • May be used as a primer for PROFLEX® elastomeric membranes in place of PR-series primers where slabs exceed 5#/1000sq.ft.-24hours vapor transmission
  • Seals dusty substrates, reduces porosity of gypsum, alkali resistant
  • Ideal for Fast-Track projects for concrete slabs not at full cure time (28 days)

MS-225 is recommended and warrantied for ‘on’ and ‘above’ grades of concrete floors. MS-225 is not guaranteed or recommended for use where hydrostatic pressure exists, and must not be used on below-grade subfloors. Use MS-225 in conjunction with a
