ELASTI-THANE MEMBRANE is a high solids, 2-component, aromatic polyurethane waterproofing membrane. It never hardens with age and remains highly flexible over a wide range of temperatures making it the ideal membrane for areas where ongoing movement is anticipated. An appropriate topcoat should be applied to the ELASTI-THANE MEMBRANE for UV protection and added durability.
ELASTI-THANE MEMBRANE is an excellent waterproofing membrane for use over concrete or wood substrates. Its’ high elongation allows it to bridge small cracks and fissures. Typical applications include recreational decks, parking structures, stadiums, plazas, roof decks, and mechanical equipment rooms
ELASTI-THANE MEMBRANE can be applied up to 30 mils over a properly primed substrate or applied up to 2 inches when using ROCK-TRED aggregates as fillers.

Limitations & For Best Results
- Do not thin this product
- Do not apply when work area exceeds 70% relative humidity or when substrate temperatures may fall to less than 5° F above dew point during the curing of the material.
- Apply the next coat within 24 hours of completing the previous coat.
- The addition of aggregates will reduce elongation.
Apply using brush, roller and squeegee ROCK-TRED product test data is based on environmental temperatures of 75° F (24° C). Viscosity and working time are always affected by temperatures above or below that mark. When applying product always consider the ambient, surface, and product temperature at the time and place of installation.
Color and Textures
ELASTI-THANE MEMBRANE is only available in gray. Most ROCK-TRED products are available in a wide range of textures using an appropriate aggregate.
Always refer to ROCK-TRED’s chemical resistance chart for specific information on each product / system or contact ROCK-TRED directly.
DO NOT allow ROCK-TRED products to freeze. All ROCK-TRED products should be properly stored above the floor on pallets or shelves, and in an area that has a constant minimum temperature of 50° F (10° C).
Always apply ROCK-TRED products to a clean / sound substrate that is free of laitance, grease, oils, debris, and curing compounds. Concrete substrates should be cured for a minimum of 28 days prior to application of product [except as otherwise noted on the individual Product Data Sheet]. Whenever possible, remove existing coatings and/or flooring systems completely; if complete removal is not possible always perform tests to determine adhesion and compatibility to the existing flooring. Surface preparation by means of a shot-blasting machine is the best and recommended method for attaining the desired profile. If the substrate is not properly prepared and the appropriate profile is not achieved, failure of the product to adhere to the substrate may occur.
Application tools and equipment can be cleaned with xylene immediately after use.
Product containers will contain product residue and must be disposed of properly. Label warnings must be observed at all times. All containers must be disposed in accordance with federal, state, and local regulations.
Always read and acquaint yourself with ROCK- TRED’S Product Data Sheet, SDS [safety data sheet], and product labels for each individual product prior to mixing and prior to use. For further assistance, product questions, additional information and/or unexpected or unusual installation conditions – contact your local representative or ROCK-TRED directly for recommendations.
