DJF-60 Dynamic Joint Filler

Permanently Flexible Joint Filler

Special features

  • Fill dynamic (moving) joints between slabs
  • Remains permanently flexible
  • Quick setting; Cures within 1 hour

Product Description
DJF-60 is a pre-measured two-component filler used for filling dynamic or moving joints in the concrete substrate. Ideal for filling joints of any width. Suitable for use with ERP 270 as a filler for joints where two slabs meet. Easy mixing and fast curing make it extremely easy to use. May be used in pre-measured containers as an entire mix or mixed in partials 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 the curing agent from the small bottle into the large container. Mix with a slow-speed drill with a mixing paddle. Partial containers can be mixed in a separate container, mix the partial crack filler with an appropriate partial amount of curing agent and shake or stir for 60 seconds.
Installation Procedure
For dynamic joints over 1/2" deep, insert a backer rod into the crack and countersink at least 1/2" below the primary surface. Pour the Dynamic Joint Filler into the crack immediately after mixing and smooth out the surface with a flat trowel.
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.
The filler will maintain its integrity and performance even when high levels of moisture or water are present. Please see below for recommended sealers if a moisture barrier is required.
