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.
- Rapid drying allows for same-day installation
- Solvent-free low VOC formula
- Low viscosity offers excellent penetration to highly porous substrates
Description
PRODUCT DESCRIPTION
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.
USES
Moisture barrier to control moisture vapor emission rates in cementitious substrates not exceeding up to 93% RH/12 #CC as a one-coat system or above 93% RH/12 lbs./1000 sq. ft./24 hrs. up to 98% RH/18 lbs./1000 sq. ft./24 hrs. as a two-coat system. For substrate consolidation on concrete, cement, and gypsum screeds. Adhesion promoter for old and new adhesive residues in conjunction with other Sika® products. For glue assist applications using a single coat in combination with SikaBond® Construction Adhesive, Sikaflex®-11FC, and SikaHyflex®-150 LM. Suitable on concrete, cement, self-levelling and gypsum substrates, OSB, plywood, water-resistant adhesive, and cutbacks.
CHARACTERISTICS / ADVANTAGES
- Rapid drying allows for same-day installation
- 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) Low viscosity offers excellent penetration to highly porous 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)
