ELASTI-THANE BASECOAT is a high solids, 2-component, aliphatic polyurethane designed to perform multiple functions. It provides the benefits of UV stability with the ability to be extended to almost any thickness when incorporating Rock-Tred aggregates and fillers.



ELASTI-THANE BASECOAT can be used as a stand alone flexible grout or as the base coat for Rock Tred foot traffic membrane systems for use in mechanical equipment rooms, mezzanines, porches and walkways, etc. ELASTI-THANE BASECOAT can be left as the finish coat or can be top coated with ELASTI-THANE TOPCOATS for added protection and beauty.


Typical Coverage

ELASTI-THANE BASECOAT can be installed as a grout up to 2 inches or as a high build component in flexible foot traffic membrane systems from 20 to 250 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.



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 BASECOAT is available in gray, black, and white. 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.


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.
