ELASTI-THANE INTERMEDIATE is a chemically curing, high solids, 2 component, elastomeric polyurethane build coat. ELASTI-THANE INTERMEDIATE can be applied over a primed substrate or ELASTI-THANE MEMEBRANE, and cures quickly to tough elastomer with a high durometer. ELASTI-THANE INTERMEDIATE is a lower viscosity traffic membrane material that can effectively encapsulate broadcast aggregates to provide a tough and durable intermediate coarse for systems exposed to vehicular or other heavy traffic.


ELASTI-THANE INTERMEDIATE, when installed with or without an aggregate broadcast, provides an excellent build coating to increase overall system thickness and durability in systems installed in parking structures, stadiums, loading docks, or anywhere the surface is exposed to severe traffic conditions.

Typical Coverage

ELASTI-THANE INTERMEDIATE is typically applied between 15 and 40 mils.

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
  • Do not apply this product heavier / thicker than the recommended spread rate / mil thickness.
  • Do not leave as a finished topcoat as discoloration will occur.


Product Application

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 INTERMEDIATE is only available in light gray. Most ROCK-TRED products are available in a wide range of textures using an appropriate aggregate.

Chemical Resistance

Always refer to ROCK-TRED’s chemical resistance chart for specific information on each product / system or contact ROCK-TRED directly.

Product Storage

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).

Surface Preparation

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

Clean Up

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.

Important Notice

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.
