Technical Data Sheet (TDS)
| Product Description |
| ULC-500 Level-Seal is a two-component urethane leveling compound capable of creating a moisture barrier of up to 18# CC or 97% RH. Level-Seal provides STC and IIC and can be directly adhered to in just under 4 hours. The product must be applied at a minimum of 1/32-in. but can be applied up to 5-in. ULC-500 is extremely durable and may be used in conjunction with other STAUF products. |
| 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, clean, free of chaps and anti-adherents, and resistant to pressure and tension. While this product can withstand any moisture, it is not a moisture barrier beyond the limitations stated below. 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). |
| Mixing of Components |
| Pour Part B completely into Part A. Thoroughly mix the two components with an electric mixer for at least 3 minutes until a uniform mixture and color are achieved. |
| Installation Procedure |
| Spread the leveling compound within approx. 20 min. Pour the compound in a line approx. 6-12 feet long and as close to the wet edge as possible. Spread to the desired thickness by raking through the compound with the appropriate notched trowel. Avoid placing a trowel directly in already spread areas as it may result in small puddles or droplets that may not flow completely out. Best results are achieved by moving in from a dry spot (not applied) and then passing through the leveler. Finish by moving the trowel to another dry spot (unapplied area) before lifting it from the floor. Use the blue roller as soon as the product is spread. 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. |
| 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. |
| 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. |
