Waterproofing Elastomeric Membrane

DESCRIPTION:

Epoxy.com Product #447 Waterproofing Membrane is a latex-based liquid membrane. Epoxy.com Product #447 offers a non-toxic, one part flexible solution for a wide range of waterproofing and vapor-proofing applications.

ADVANTAGES:

Flexible and elastic membrane
Water-based compound that can be applied to damp surfaces
Tough abrasion-resistant coating
Low water vapor permeability
Non-staining
Ultraviolet resistant
Bonds well to many surfaces
Can be applied by brush, roller or spray
Quick drying; typically dry to the touch in one hour
Low odor
Alkali-resistant, can be applied to alkaline surfaces

WHERE TO USE:

The liquid membrane can be used in a wide variety of applications where high flexibility and good bonding are required.

Floors—typical applications include use beneath self-leveling floor products or above trowelable underlayments where the original membranes have been punctured.
Basements—The liquid membrane can be used as part of a waterproofing system below ground level.
Walls—The liquid membrane has good adhesion to many types of surfaces.

APPEARANCE:

The liquid vapor membrane is waterbased latex that dries to form a tough, water and vapor-resistant film. The latex is environmentally friendly and solvent free. The liquid membrane has low odor. Epoxy.com Product #447 is available in a variety of colors. The color of the liquid compound may differ slightly from the color of the dried membrane. The formulated product is a viscous liquid similar in consistency to a thick water-based paint.

SURFACE PREPARATION:

Newly prepared surfaces should be smooth and have a troweled or brushed finish. All masonry should be flush pointed. Defects in existing surfaces should be repaired. The surface needs to be clean and free of dust, loose material, and free surface water. The membrane should not be applied under wet conditions or where these conditions are likely to occur before the membrane has fully dried. It is sometimes advantageous to pre-wet the substrate so it is damp, yet free of standing water, to improve adhesion of the liquid membrane. Check adhesion to various surfaces by applying the product to a small sample area before starting any job.

APPLICATION:

The liquid may be applied by brush, roller or airless spray. If necessary, the compound can be diluted with water. However, care should be taken to ensure the correct dry-coat thickness is applied and that the drying time is not unacceptably extended due to the dilution.

The thickness of the dried membrane depends on the application requirements and method of application. For a single dry coat thickness of more than 0.3 mm, it is recommended that the membrane be applied by airless spray. If airless spray is used, single dry-coat thickness of up to 1 mm can be obtained.

If two coats are being applied, it is recommended that the coats be applied at right angles to each other. Before applying the second coat, it is necessary to let the first coat become dry to the touch. It is preferable that the second coat is applied within 24 hours after the application of the first.

COVERAGE:

Two coats are required. Epoxy.com Product #447 should be applied at a rate of 80 square feet per gallon.

PACKAGING:

1 gallon, 5 gallon and 55 gallon drums

SHELF LIFE:

One (1) year

LIMITATIONS:

Protect from freezing. Do not apply below 40°F.

CAUTION:

Avoid ingestion of material. Wash thoroughly after handling.
