Technical Data Sheet (TDS)
| Product Description |
| Cement and dispersion powder-based leveling compound. Contains no solvents, no VOC. Can be used under wood flooring, resilient flooring, and ceramic tile. - Synthetic resin reinforced. - Self-leveling, forms a flat and even surface. - Levels up to a 5-inch variation in subfloors. |
| 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 |
| Moisture content in concrete subfloors must be below 3#/24hr/1000SF using the Calcium Chloride Test or below 75% RH using an in-situ probe per ASTM F1869 and F2170. |
| Prior to installation, the subfloor must be checked according to applicable installation guidelines. It must be solid and sound, permanently dry, clean, free of chaps and anti-adherents, and resistant to pressure and tension. The moisture content of all floors must be measured before installation. |
| 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). |
| Apply suitable primer or sealer to the subfloor before spreading cement or gypsum-based leveling compounds to increase the bond. |
| Mixing of Components |
| Fill a bucket with the correct amount of cold water. Wear a proper dust mask when using powdered products in enclosed areas. While stirring, add powder to the water and continue stirring until an even mixture is formed. Use an electric mixer with 600 to 800 RPM. Stir for two more minutes, wait one minute, and stir again for one minute. |
| Installation Procedure |
| Spread the leveling compound within approx. 20 min. Do not pour the compound in one spot but evenly over the entire (approx. 6x6 ft.) area to be covered. The self-leveling compound does not need to be leveled mechanically and forms an even surface by itself. Protect the leveling compound from direct sunlight and draft during drying. |
| 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. |
