Lithium Silicate Below Grade Concrete Vapor Barrier Stop Water/Efflorescence 5Ga

Description

CMW 8000 Lithium Silicate Concrete Vapor Drive Moisture Barrier 5 Gallon Pail
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 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 8000 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 8000 may be painted or stained over, and will accept concrete topping or mastics for floor tile etc
CMW 8000 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 8000 adds 20% - 40% increase in density to the concrete while increasing the strength of the cured concrete. CMW 8000 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 8000 Ready-to-Use Lithium Silicate Vapor Drive Barrier/Densifier needs no mixing and can be used straight out of the container. Also comes as an optional concentrate.
CMW 8000 Lithium Silicate Solves Concrete Moisture Problems
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
