ELASTI-FLEX WB GLOSS is a water clear, two-component, water-based aliphatic polyurethane SMART coating. This unique non-yellowing polyurethane coating produces an exceptionally hard, yet flexible high gloss finish with high level abrasion and stain resistance. ELASTI-FLEX WB GLOSS remains non-chalking, has superior UV resistance, provides excellent long-lasting protection from many chemicals and offers superior wear through durability while producing no strong odors during application or curing. The designation of SMART coating refers to ELASTI-FLEX WB GLOSS’ ability to mimic the visco-elastic properties of coatings installed below. By mirroring these properties this SMART coating will move in unison with the base coatings and will self-heal when the surface is punctured.



ELASTI-FLEX WB GLOSS is the best protective finish coat for ROCK-TRED’s SOFT FLOORING SYSTEMS. When used as the final coat its SMART abilities allow it to move with the soft, flexible undercoats unlike traditional high performance urethane finish coatings. ELASTI-FLEX WB GLOSS’ outstanding stain resistance and durability make it well suited across many industries including animal/human healthcare, sports facilities and where anti-fatigue flooring systems are required.

Limitations & For Best Results

  • Do not apply when Humidity exceeds 70% or when the substrate temperature is 5˚F above dew point and falling.
  • Allow each coat to dry to completely prior to re-coat
  • Do not apply this product heavier / thicker than the recommended spread rate / mil thickness or foaming or discoloration may occur.
  • Do not split kits - full unit mixing is very critical to product performance.
  • Do not entrain air when mixing
  • Do not thin with water or solvent.
  • If applying a 2nd coat, the first coat of ELASTI-FLEX WB GLOSS must be lightly sanded to promote inter coat adhesion and the 2nd coat must be applied within 24 hours of completing the previous coat.



Product Application


Apply via dip and roll using a 5/16” microfiber roller. Vertical applications may be made via airless sprayer and back rolling (contact ROCK-TRED for more information on spray applications). ROCK-TRED product test data is based on temperatures of 75˚F. Viscosity and working time are affected by temperatures – always consider the ambient, surface, and product temperature at the time and place of installation.


Color and Textures

ELASTI-FLEX WB GLOSS is only manufactured in clear and is not recommended for tinting with ROCK-TRED Universal Colorants. Adding any broadcast or mixed in media for color or texture is not recommended for this product as its flexibility and SMART characteristics will be compromised.


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. Mechanical preparation by means of a diamond grinding machine to a minimum CSP-2 profile followed by application of an appropriate ROCK-TRED primer or SOFT SYSTEM system is the best and recommended installation method for ELASTI-FLEX WB GLOSS applications. 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 soap and water immediately after use, or with solvent once the product has begun to cure.



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 Technical 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. Kit components are pre-measured for optimal performance. Catalyzation errors due to incorrect mixing in the field voids product warranty.
