CMW 8000 Lithium Silicate Concrete Vapor Barrier Moisture Barrier

Product Description

CMW ***0 Lithium Silicate Concrete Vapor Drive Moisture Barrier

is a clear, colorless topically applied penetrating lithium silicate blended system designed to stop concrete floor coatings and floor coverings from de-bonding due to hydrostatic vapor pressure coming up through a below grade basement concrete slab, on-grade slab and elevated deck slabs. This system stops hydrostatic pressure, capillary action and moisture migration by creating a negative and positive side moisture barrier. The CMW ***0 is used prior to application of a floor coating or floor covering where excess moisture coming up through the concrete is a potential problem. The CMW ***0 may be painted or stained over, and will accept concrete topping or mastics for floor tile etc

 CMW ***0 is a lithium silicate blended sealer that penetrates into the concrete slab. A reaction occurs between the lime and excess Portland cement, which is always present, and forms Calcium Silicate Hydrate (CSH). This process will encapsulate the moisture to create a permanent break in the capillaries of the concrete, stopping the passage of liquids and vapors through the concrete.

 As a densifier, the CMW ***0 adds *0% - *0% increase in density to the concrete while increasing the strength of the cured concrete. CMW ***0 will purge alkalai salts and contaminents to the surface over a several day period and help eliminate existing effllorescnce problems from reocurring. It can also be combined with a water repellent treatment for superior protection. CMW ***0 Lithium Silicate Vapor Drive Barrier/Densifier is available in ready-to-use and concentrate.

• A true moisture vapor blocker, vapor transmission/hydrostatic pressure reducer
• Permanent - becomes part of the concrete
• Will stop minute fracture weeping of moisture (may require several coats)
• Stops effloresence – purges salts and residual acidic materials out
• Insures longer lasting applications of floor coatings in areas of vapor pressure
• Applied to new or old concrete
• Improves concrete strength and chemical resistance
• Non-toxic, non-flammable and no odor
• Reduces and/or Eliminates hairline cracks and curing cracking in new concrete
• Assists in providing a uniform curing on new concrete via chemical reaction
• Acts as an adhesion promoter for surface applied coatings
• Used in joints to stop vapor & water pressure from damaging joint materials
• Does not change the surface appearance
• Surface will take color stain
• Helps concrete stains to retain color longer
• In areas exposed to high humidity and salt air - reduces potential of corrosive activity to the rebar within the econcrete
• Apply with Airless or Garden Sprayer or roller
