CHEM-THANE WBP GLOSS is a zero VOC, water clear, two-component, waterborne aliphatic polyaspartic polyurethane. This unique non-yellowing coating produces an exceptionally hard finish with high level abrasion and very good stain resistance.  CHEM-THANE WBP 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.



CHEM-THANE WBP GLOSS is an ideal protective finish coat for ROCK-TRED’s standard and decorative floor and wall systems.  Its excellent durability and abrasion resistance makes CHEM-THANE WBP GLOSS a perfect finish coat across industries such as pharmaceutical, healthcare, warehousing and manufacturing.  This waterborne product is easy to apply, environmentally safe and meets all USDA/FDA guidelines for installation in federally inspected facilities.

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.
  • If applying a 2nd coat, the first coat of CHEM-THANE WBP 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.
  • May be applied directly to dry, prepared concrete, but an appropriate ROCK-TRED primer or base system is recommended.
  • 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 or applying.
  • Thinning with up to 15% clean water is recommended when applying to floors.   

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

CHEM-THANE WBP GLOSS is manufactured in clear only. It is not recommended for tinting with ROCK-TRED Universal Colorants.  Most ROCK-TRED products are available in a wide range of textures using an appropriate broadcast aggregate, but aggregate larger than 240 mesh may not remain in CHEM-THANE WBP GLOSS under use.  Approximately 1.42 pounds of ROCK-TRED’s 240 grit Aluminum Oxide powder may be added into 1 gallon of CHEM-THANE WBP GLOSS at the time of mixing to increase abrasion resistance and the cured coating’s coefficient of friction.  Adding AO powder will leave a superfine grain texture in the finish and will reduce light reflectivity.   Repeatedly stirring the product during application to avoid the AO settling and then careful and even application is needed to avoid roller marks when AO powder has been added.


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 grinder or shot-blasting machine to a minimum CSP-2 profile followed by application of an appropriate ROCK-TRED primer or base system is the best and recommended installation method for CHEM-THANE WBP GLOSS applications, but this coating may be applied directly to prepared, dry concrete.  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 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 Area Sales 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.
