Modified Acrylic Cove Base Adhesive
Special features
| Product Description |
| CBA-843 is an acrylic latex based adhesive, non-flammable, and specifically formulated for the installation of rubber or vinyl cove base. CBA-843 is suitable for installations to almost any clean, dry, and structurally sound wall surface, and is waterresistant when cured. |
| Pre-Installation Checklist |
| A successful installation requires proper preparation of the substrate. Read and understand all applicable guidelines and technical data sheets before installation. Follow industry standards and covering manufacturer's recommendations for substrate moisture content, design, layout and application of covering materials. All sub constructions must meet the specific requirements of the wall covering to be installed. |
| Sub Floor Examination |
| Prior to installation, the substrates must be checked according to applicable installation guidelines. It must be solid and sound, flat, permanently dry, clean, free of chaps, indentations and anti-adherents, as well as resistant to pressure and tension. |
| Moisture content in concrete sub floors must be below 12#/24hrs/1,000 sq. ft. using the Calcium Chloride Test or less than 90% RH using the in-situ test per ASTM F1869 and F2170. If installing sheet goods the limitations are 85% and 8# respectively. |
| Sub Floor Preparation |
| Depending on type and condition of sub floor, a mechanical treatment (e.g. mechanical brushing, grinding or sanding) may be required. Intensity of such work must be determined at the site by the installer. Dust, paint, residual adhesives or other surface contaminants must be removed by suitable means. Cleaning the surface with an industrial vacuum cleaner is recommended. Cracks and gaps must be filled with concrete crack filler unless they are expansion joints. Level when necessary to 3/16 inches within 10 feet. Heated sub floors, gypcrete, wooden sub floors, levelers, patches and light weight concrete must be primed. Fast curing cementitious leveling or patching compounds might reduce the flash and work time of water based products due to absorption. |
| Installation Procedure |
| Apply adhesive directly to base or wall. Stay 1/8? away from top of base to prevent oozing. After placing base roll with a hand roller. Continue in like manner until all base has been placed. Roll toward previously installed section to insure a tight fit. |
| Storage |
| Store and transport protected from freezing. Recommended minimum temperatures are 35 °F for transport and 40 °F for storage. Do not stir product if frozen, allow to thaw completely. |

| This adhesive will maintain its integrity and performance even when higher levels of moisture are present. While adhesive can withstand up to 12#/24 hrs/1,000 SF (Calcium Chloride Test) and 90% RH (in-situ probe) of moisture, it does not qualify as a moisture inhibitor. Please see below for recommended sealers if a moisture barrier is required. Not suitable for areas with excessive topical moisture (i.e. melting snow, repeated flooding, pressure washing) or extreme horizontal shear forces; use R-Series adhesives under these circumstances. If sheet goods are installed, the limitations or 85% and 8# respectively. |
