Pressure Sensitive Adhesive
Special features
| Product Description |
| PSA-832 has been formulated to ensure superior adhesive performance under the very demanding conditions commonly found in today's fast-paced construction and raises the bar for the performance of pressure-sensitive adhesives. PSA-832 may also be used to install vinyl tile (LVT). The CRI Green-label Plus Adhesive Certification Program has certified PSA-832 as a "zero VOC" adhesive. PSA-832 is a premium, high-performance pressure-sensitive adhesive [PSA] with a tenacious bond. It is the professional?s choice for installation of vinyl tile [LVT], vinyl plank, modular carpet tile, as well as, fiberglass-reinforced [F/G] sheet vinyl. This adhesive can be used on most commonly found sub-floors. This aggressive PSA allows for the removal and replacement of carpet tiles while maintaining a high standard of performance. PSA-832 may also be used to install approved carpet cushions in double-glue installations. PSA-832 has a long working time, spreads easily, and affords easy cleanup. PSA-832 is a nonhazardous, VOC compliant adhesive with zero VOC's (calculated). PSA-832 is protected by the CleanGuard® two-stage antimicrobial. |
| 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. The backing of all flooring material 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/1000SF using the Calcium Chloride Test or less than 99% RH using the in-situ test per ASTM F1869 and F2170. If installing sheet goods, the limitations are 85% and 8#, respectively. |
| The following conditions MAY NOT be present: Hydrostatic pressure, Excessive vapor emissions, Missing or compromised vapor barrier, Standing water or visible dampness, Uneven and/or unapproved subfloor materials, Improper substrate preparation, Excessive exterior water (damaged water pipes, sinks, icemakers, faulty plumbing, flooding, etc.), Excessive topical moisture, improper ventilation or conditioning, or faulty maintenance of flooring, Use of Adhesives as a moisture control system below grade. |
| 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- degree angle. Observe the appropriate flash time (if applicable). 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 subfloor to flooring is achieved. Roll flooring approx. 15-30 min. after installation with a 75-100# roller if recommended by the flooring manufacturer. Push down raised edges approx. 30-60 min. after installation. |
| Storage |
| Store and transport protected from freezing. Recommended minimum temperatures are 10°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 99% 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#. |
