Technical Data Sheet (TDS)
| Product Description |
| CCF-40 is a pre-measured two-component filler used for the repair or filling of voids in the concrete substrate. Ideal for filling cracks in concrete subfloors of any width. Suitable for use with ERP 270 as a filler for voids such as scored joints. Easy mixing and fast curing make it extremely easy to use. May be used in pre-measured bottles as an entire mix or maybe mixed in a 1:1 ratio for the amount needed. |
| 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, 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). |
| Mixing of Components |
| Pour all of Part A into the bottle with Part B. Close the cap and shake for 15 seconds. Do not stir. Partial bottles can be mixed in a separate empty container, mix a 1:1 ratio of Parts A & B and shake for 15 seconds. Do not stir. |
| Installation Procedure |
| Widen the crack in the floor to approx. 1/4 inch using an angle grinder, also cut the floor across the crack, and install floor brackets. Pour the concrete crack filler into the crack immediately after mixing and smooth out the surface with a flat trowel. Broadcast sand into the wet crack filler and vacuum off after it has dried to improve adhesion of subsequent levelers, sealers, or adhesives. |
| 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. |
| 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. |
