A black, liquid applied, single-component, moisture-cured 100% solids, polyurethane waterproof coating, designed to form a low odor, seamless, flexible rubber membrane impervious to moisture.
Composition: Polyurethane elastomeric membrane.
The product is fully bonded to the substrate so water cannot flow underneath the lining as it can with sheet lining materials.
Limitations: Containers that have been opened must be used within one or two days since it is a moisture-reactive material. It sets up when exposed to air. All surfaces must be completely free of foreign matter and dry.
Color: Black only.
Standards: A.S.T.M. C836-89.
WARNINGS AND HAZARDS:
Before using the products, always refer to MSDS for important warnings and

suitable eye protection. Always wash hands before eating.
EPOXY.COM PRODUCT #408 is best applied by airless spray. However, when the job does not lend itself to spraying, it may also be applied by roller, brush or squeegee.
All cracks over 1/16" (1.6mm) in width must be filled and covered with EPOXY.COM PRODUCT #372 a Knife grade version of this Product. This product may be applied by trowel or caulking gun. There is no need to wait for this product to cure before applying the EPOXY.COM PRODUCT #408 since they are completely compatible.
A dry film thickness of 60 mils (1.5mm) is recommended over concrete surfaces. Extremely porous substrates should be filled prior to coating or receive additional EPOXY.COM PRODUCT #408
Application must be made uniformly to avoid thin spots and care must be taken to avoid pinholes and repair them should they occur. Where a two coats application is preferred, allow a 24 hour cure time between coats.
Protection board must be used prior to backfilling or pouring the concrete topping slab.
Satisfactory results depend not only upon quality products but also upon factors
beyond our control; methods of application and site conditions are examples of
such factors and can affect product performance. This warranty consequently
