Ultra Premium Commercial Carpet Adhesive
Special features
| Product Description |
| BCS-827 Ultra Premium Adhesive is specifically formulated for the heaviest commercial applications and has been formulated to ensure adhesive performance under the very demanding conditions commonly found in today?s fast-paced construction. This ultra-strong, low VOC adhesive is excellent for woven carpets, those with stiff unitary backings, and attached cushion backings. BCS-827 Ultra Premium Adhesive is THE professional's choice for Double-Glue and pattern matching applications. This formula has an extended working time and superior re-tack engineered to maximize installer efficiency. BCS-827 Ultra Premium Adhesive can be used for the following carpet backings and floor coverings: - Direct-Glue: woven polypropylene (ActionBac®, hot melt, etc.) latex unitary, polyurethane foam-backed (Enhancer® I,II,III,IV, BioCel?, and Durafoam), rubber backs, woven, axminster, needlepunch, and jute. - Double-Glue: BCS-827 is recommended for double-glue "carpet to pad" applications with specific carpet backings approved by STAUF for this application. This adhesive can also be used to adhere to approved double-glue carpet cushions. - Although this adhesive is formulated for carpet installations, because of its non-staining characteristics, it can be used to install felt-backed sheet vinyl. NOTE: This adhesive is not recommended for vinyl-backed (PVC) sheet goods or carpets with urethane unitary or vinyl (PVC) backings. |
| Pre-Installation Checklist |
| A successful installation requires proper preparation of the subfloor. Read and understand all applicable guidelines and technical data sheets before installation. Follow industry standards and flooring manufacturers' recommendations for subfloor moisture content, design, layout, and application of flooring materials. All flooring material's backing must be solid, sound, and free of anti-adherents. All slab constructions must meet the specific requirements of the floor covering to be installed. |
| Sub Floor Examination |
| Prior to installation, the subfloor 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. The moisture content of all floors must be measured before installation. |
| Moisture content in concrete subfloors must be below 12#/24hr/1,000SF 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 the type and condition of the subfloor, a mechanical treatment (e.g. mechanical brushing, grinding, or sanding) may be required. The 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 subfloors, gypcrete, wooden subfloors, levelers, patches, and lightweight 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 |
| Spread the adhesive with the appropriate notched trowel. Avoid excessive adhesive thickness by passing the trowel evenly through the adhesive at a 45° angle. Observe the appropriate flash time (if applicable). Next, lay the flooring into the adhesive, correctly position it and press down firmly. Be sure to check the back of the flooring to ensure a good adhesive transfer from the subfloor to flooring is achieved. Roll flooring approx. 15-30 minutes after installation with a 35# roller for double glue and 75-100# roller for sheet vinyl if the flooring manufacturer recommends. Push down raised edges approx. 30-60 min. after installation. |
| Storage |
| Store and transport protected from freezing. Recommended minimum temperatures are 35°F for transport and 40°F for storage. Do not stir the product if frozen, allow it to thaw completely. |
| Limitations |
| When using other than STAUF products in conjunction with STAUF primers, sealers, leveling compounds, or adhesives, STAUF denies any and all responsibility for any ensuing problems and/or damages without prior written authorization from STAUF. |
| In case of an accident, injury, spill, or exposure, see SDS for information. Consult the Technical Data Sheet at www.staufusa.com for updated information. |
| This adhesive will maintain its integrity and performance even when higher levels of moisture are present. While adhesive can withstand up to 12#/24hr/1000SF (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 are 85% and 8#. |
