Description

CHEM-WALL BLOCK FILLER is 100% solids, 2-component, vertical grade epoxy formulated for priming, sealing and filling porous substrates such as CMU walls or vertical cast in place concrete. CHEM-WALL BLOCK FILLER can also be used as a patching material on irregular vertical, overhead and horizontal surfaces by adding a thickener such as fumed silica. CHEM-WALL BLOCK FILLER is VOC compliant and meets all USDA guidelines for use in federally inspected facilities.

Uses

CHEM-WALL BLOCK FILLER is the recommended primer/sealer and body coat for most ROCK-TRED wall systems applied over highly porous substrates. It is also the recommended body coat in the CHEM-WALL MAT LAY UP SYSTEM.

Typical Coverage

CHEM-WALL BLOCK FILLER is typically roller or airless spray applied at a spread rate between 160 and 65 square feet per gallon depending on substrate profile & project requirements. CHEM-WALL BLOCK FILLER can be applied wet on wet in 2 thin coats without allowing for full cure between coatings when extra thickness is required to seal a very porous substrate.

Limitations & For Best Results

• Do not thin this product
• Do not apply when humidity exceeds 70% indoors
• Do not allow to puddle during application.
• Allow each coat to dry to ‘tack free’ or clear prior to re-coat
• When re-coating, always 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, airless sprayer and/or 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

Apply using brush, roller, airless sprayer and/or squeegee. ROCK-TRED product test data is based on environmental temperatures of 75F (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.

Chemical Resistance

Always refer to ROCK-TREDs 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 50F.

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 systems completely; if complete removal is not possible always perform tests to determine adhesion and compatibility to the existing coating. 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.

Disposal

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-TREDs 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.
