Epoxy.com Product #417

Elastomeric Membrane Waterproofing System Coaltar-Free

This Product has been Replace by Epoxy.com Product #449

This Material requires a minimum product purchase. Please see our Products That Require a Minimum Order Page, or contact Epoxy.com for more information.


A black, liquid applied single-component moisture-cured polyurethane coating, designed to form a seamless, flexible rubber membrane impervious to moisture. Composition: Polyurethane elastomer. Type I: For horizontal surfaces. Type I: For vertical surfaces.

Type II: For vertical surfaces.



Once cured, EPOXYSYSTEMS’ PRODUCT #417 allows expansion and contraction over a broad temperature range and maintains waterproofing properties under continuous exposure to water. EPOXYSYSTEMS’ PRODUCT #417 Type II has a thixotropic consistency and may be used on vertical as well as horizontal surfaces. EPOXYSYSTEMS’ PRODUCT #417. remains flexible from -75°F to +175°F (-59°C to 79°C). EPOXYSYSTEMS’ PRODUCT #417 waterproof membrane is intended for use wherever overflow water must be contained.


Suggested areas of application are as follows:

  • Waterproofing in between concrete slabs, such as parking decks, roof decks or courtyard areas over subterranean parking.

  • Waterproofing below grade exterior walls or foundations and basements or other structures that are to be backfilled.

  • Waterproofing inside planter boxes.

  • Waterproofing under terrazzo or tile floors.

  • Waterproofing under shower-pans, kitchen, laundry and bathroom floors.

  • Waterproofing inside of elevated swimming pools.

  • Waterproofing of occupied areas under malls, plazas and promenades.

  • Water Tanks: EPOXYSYSTEMS’ PRODUCT #417 has been used with outstanding success as a lining for emergency water storage tanks. The EPOXYSYSTEMS’ PRODUCT #417 bridges hairline cracks and because of the materials flexibility, allows them to move with changes in temperature. The product is fully bonded to the substrate so water cannot flow underneath the lining as it can with sheet lining materials.



  • EPOXYSYSTEMS’ PRODUCT #417 is a single-component compound that may be used directly from the container with no mixing required.

  • The addition of catalysts are not necessary, as EPOXYSYSTEMS’ PRODUCT #417 is a moisture-cured compound.

  • May be applied by spray equipment, brush, roller, squeegee or trowel, without the need for heating the material.

  • May be applied over concrete, stone, brick, cement blocks, wood, metal, asbestos and most other surfaces.

  • EPOXYSYSTEMS’ PRODUCT #417 cuts cost of application by eliminating mixing, splicing, sealing tapes, adhesives and other labor consuming methods required when installing other conventional types of waterproofing systems.

  • The superior flexibility and elongation properties of EPOXYSYSTEMS’ PRODUCT #417 allows expansion and contraction with the substrate, without cracking or becoming brittle.

  • Does not contain any potentially hazardous coal tar.


  • EPOXYSYSTEMS’ PRODUCT #417 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 EPOXYSYSTEMS’ PRODUCT #417 Non-sag. This product may be applied by trowel or caulking gun. There is no need to wait for this product to cure before applying the EPOXYSYSTEMS’ PRODUCT #417 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 EPOXYSYSTEMS’ PRODUCT #417

  • EPOXYSYSTEMS’ PRODUCT #417 may be used in a single 60 mil (1.5mm) application over sound surfaces without danger of gassing. Application must be made uniformly to avoid thin spots and care must be taken to avoid pinholes and repair them should they occur. Coverage to obtain 60 dry mils is 20 sq. ft./gallon (0.48 m2/Liter). Where a two coats application is preferred, two coats at 40 sq. ft./gallon (0.96 m2/liter) per coat are to be applied, allowing a 24 hour cure time between coats.

  • Protection board must be used prior to backfilling or pouring the concrete topping slab.


Shelf Life: 6 months at 77°F (25°C) when stored indoors in cool and dry location.

Color: Black only.

Standards: A.S.T.M. C836-89.

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 before recoating it with EPOXYSYSTEMS’ PRODUCT #417..
