Special features

  • Permanently closes cracks in sub floors

Product Description
CCF-40 is a pre measured 2 component filler used for the repair or filling of voids in concrete substrate. Ideal for filling cracks in concrete sub floors 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 may be mixed in a 1:1 ratio for amount needed.
Pre-Installation Checklist
A successful installation requires proper preparation of the sub floor. Read and understand all applicable guidelines and technical data sheets before installation. Follow industry standards and flooring manufacturer's recommendations for sub floor moisture content, design, layout and application of flooring materials. All slab constructions must meet the specific requirements of the floor covering to be installed.
Sub Floor Examination
Prior to installation, the sub floor must be checked according to applicable installation guidelines. It must be solid and sound, permanently dry, clean, free of chaps and anti-adherents, as well as resistant to pressure and tension. Moisture content of all floors must be measured before installation.
Sub Floor Preparation
The condition of the sub floor 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 pollutants MUST be removed by suitable means. Extent of sub floor preparation can only be determined at the site by the installer. Clean the surface with an industrial vacuum cleaner, tack or damp mop floor before application. Do not use sweeping compounds as most 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
Pour all of part A into the bottle with part B. Close cap and shake for 15 seconds. Do not stir. Partial bottles can be mixed in a separate empty container, mix one part A with 1 part 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 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 product if frozen, allow 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.
