Technical Data Sheet (TDS)
| Product Description |
| STAUF ACS-210 True-Seal is a pure acrylic-based sealer for professional flooring installation. It does not contain any solvents, isocyanates, or other harmful materials. It is, therefore, ozone and environmentally safe, certified as "very low emissions", and certified "green". ACS-210 is uniquely developed to mitigate the moisture pressure from a humid subfloor to an acceptable level for flooring installation and to bridge minor cracks in the subfloor. ACS-210 spreads easily and creates a dust-free and evenly absorbent surface ready for installation of flooring. It has superior coverage and dries very quickly. |
| 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 8#/24hr/1000SF using the Calcium Chloride Test or less than 85% RH using the in-situ test per ASTM F1869 and F2170. Use epoxy moisture barrier for higher moisture installations. |
| Prior to installation, the subfloor must be checked according to applicable installation guidelines. It must be solid, sound, clean, porous, free of chaps, anti-adherents, and resistant to pressure and tension. Confirm sufficient porosity by performing a water drop test according to ASTM F3191-16. Check for missing or compromised vapor barriers and hydrostatic pressure by carrying out RH or CaCl moisture tests following ASTM standards F1869-16 or F2170-19. Results of 99% RH or 25# CaCl could indicate a higher moisture content in the slab than what tests can measure, and there might be hydrostatic pressure and/or a compromised or missing vapor barrier. |
| Sub Floor Preparation |
| The subfloor's condition will determine which type of mechanical treatment is required (e.g., wire brushing, sanding, grinding, or shot blasting). Dust, paint, curing compounds, sealers, residual adhesives, or other surface contaminants MUST be removed, and a porous surface must be achieved by suitable means. The installer can only determine the extent of subfloor preparation at the site. Clean the surface with an industrial vacuum cleaner and tack the floor with a damp microfiber mop before application. Do not use sweeping compounds unless water-based, as most others contain oil or wax, which will act as an anti-adherent and prevent primers, sealers, leveling compounds, coatings, and/or adhesives from bonding to the concrete. Cracks and gaps must be treated before application of primers, sealers, leveling compounds, coatings, and/or adhesives (see Technical Information #19 @ www.staufusa.com). |
| Installation Procedure |
| Shake before use and apply sealer undiluted with the appropriate applicator. Make sure the sealer is spread evenly. Do not exceed the maximum coverage. Higher temperatures speed up the drying time. |
| 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. |
| Do not use on subfloors with a moisture reading above 8#/24hr/1000SF (Calcium Chloride Test) or 85% (RH with in-situ probe). |
| 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. |
| Do not dilute primer/sealer or mix with other products. |
