Sika® MB EZ Rapid

One component rapid drying moisture barrier, adhesion promoter, and substrate consolidator for flooring on critical substrates

One-Component, Rapid-Drying, Polyurethane Resin, Moisture Mitigation System and Substrate Solidifier. Sika® MB EZ Rapid can be used as a fast-curing moisture mitigation system for interior use only on cement-based substrates up to 98% RH or 18 lbs./1000 sq. ft./24 hrs. before applying SikaLevel® underlayments and SikaBond® adhesives. Sika® MB EZ Rapid can be used as a solidifier over a variety of critical substrates, such as adhesive residues and gypsum substrates.

  • Solvent-free low VOC formula
  • Low viscosity offers excellent penetration to highly porous substrates
  • High coverage allows for cost saving
  • Single component formula
  • Colored formula to ensure uniform coverage
  • Solidifier of weak substrates
  • Can be used as a vapor retarder in place of felt paper on wooden subfloors for glue assist applications
  • Will prevent moisture related issues like cupping if substrate moisture levels are below Sika® MB EZ Rapid’s acceptable levels
  • Excellent adhesion promoter to a wide range of residues
  • Class II vapor retarder >0.1 perm and ≤1.0 perm (1 coat)
  • Permeance (ASTM E96): ≤ 0.4 perm (2 coats)
