Technical Data Sheet (TDS)
| Product Description |
| DWS-660 is a one-component water-based acrylic sealer that offers excellent resistance to water blushing without the objectionable solvent odors associated with solvent-based sealers. This product has a fast set time and good stain resistance. |
| Pre-Installation Checklist |
| A successful installation requires proper preparation of the subfloor. Read and understand all applicable guidelines and Technical Data Sheets before installation. |
| Sub Floor Examination |
| Prior to installation, the subfloor must be checked according to national standards. It must be solid and sound, level, free of indentations, and resistant to pressure and tension. |
| Sub Floor Preparation |
| The condition of the subfloor 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 achieved by suitable means. The extent of subfloor preparation can only be determined at the site by the installer. 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 they are water-based as most others will 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 prior to application of primers, sealers, leveling compounds, coatings, and/or adhesives (for details see Technical Information #19 @ www.staufusa.com). |
| Mixing of Components |
| Single component system. Shake well and pour into a sprayer. |
| Installation Procedure |
| Spray apply the product using a garden sprayer or drum pump with a spray attachment. Spray evenly and make sure to cover all areas. On very smooth surfaces, use a microfiber applicator to smooth out the product. |
| If a recoat is desired make sure the previous coat has dried completely. Pressing your fingernail into the coat should not leave an impression. Colder temperatures and higher humidity will prolong drying times. Do not re-coat with any product except the one previously applied. |
| 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 install during rain. |
| Subfloor temperatures between 32-50°F (0-10°C) will dramatically increase drying time up to 24 hours. Never install the product when subfloor temperature is below freezing or if condensation could occur on the subfloor within 24 hours after application. |
| 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. |
| Some cleaners may affect the color of the floor installed. Test cleaner in a small area with the intended technique. If no discoloration occurs proceed to clean the entire floor. Restrict traffic and cleaning until the product has fully cured. |
| Surface may be slippery, especially when wet or contaminated. Keep the surface clean and dry. |
