CHEM-THANE WB MATTE V.2014 is a water clear, twocomponent, water-based aliphatic polyurethane. This unique non-yellowing polyurethane coating produces an exceptionally hard matte finish with high level abrasion and stain resistance. CHEM-THANE WB MATTE V.2014 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 WB MATTE V.2014 is an ideal protective finish coat for ROCK TRED’s standard and decorative floor and wall systems. It’s hard finish and very high abrasion resistance makes CHEM-THANE WB MATTE V.2014 an excellent and low reflectivity finish coat across industries such as pharmaceutical, healthcare, warehousing and manufacturing. This water based product is easy to apply, environmentally safe and meets all USDA/FDA guidelines for installation in federally inspected facilities.
CHEM-THANE WB MATTE V.2014 is typically applied at 500-600 square feet per gallon.

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 WB MATTE V.2014 must be lightly sanded to promote inter-coat adhesion and the 2nd coat must be applied within 24 hours of completing the previous coat.
- Do not apply this product heavier / thicker than the recommended spread rate / mil thickness or foaming, discoloration or loss of MATTE finish may occur.
- Do not thin with water or solvent.
- May be applied directly to prepared concrete, but an appropriate ROCK-TRED Primer is recommended.
- Do not split kits - full unit mixing is very critical to product performance.
- Do not entrain air when mixing.
- Due to low light reflectivity a clear matte finish will produce a noticeable color shift when applied over a colored base coating.
- Take extra care to apply uniformly over dark colored base systems to avoid roller marks or sheen differences in the finish. These same slight sheen differences will not be perceptible over light colored base systems. For difficult installations over dark colored base systems where there is no tolerance for even slight sheen differences using CHEM-THANE 509 Satin or CHEM-THANE WB GLOSS instead of CHEM-THANE WB MATTE V.2014 is advised.
Apply via dip and roll in one direction using a 5/16” microfiber roller cover. After initial roll strike off the finish with a light, single direction final back roll. 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 WB MATTE V.2014 is only manufactured in clear and 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 larger aggregate may not remain into thin coats of CHEM-THANE WB MATTE V.2014. Approximately 1.42 pounds of ROCK-TRED’s 240 grit Aluminum Oxide powder may be added into 1 gallon of CHEMTHANE WB MATTE V.2014 at the time of mixing to increase abrasion resistance and the cured coating’s coefficient of friction. Adding AO powder will require the coating to be repeatedly stirred during application to avoid settling and then careful and even application to avoid roller marks.
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. 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 base system is the best and recommended installation method for CHEM-THANE WB MATTE V.2014 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.

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.
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.
Having control of the product from development to raw materials to production means that Rock Tred offers a vastly superior product for the money. Dr. Steve Hodges, Product Technical Director discusses how all Rock Tred Products are put through a rigorous set of product quality tests and are supported all the way through application.
