Product Description
DJF-60 is a pre measured 2 component filler used for filling of dynamic or moving joints in 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 may be mixed in partials 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 @
Mixing of Components
Pour all of the curing agent from the small bottle into the large container. Close cap and shake for 60 seconds. Partial containers can be mixed in a separate container, mix partial crack filler with appropriate partial amount of curing agent and shake or stir for 60 seconds.
Installation Procedure
For dynamic joints over 1/2" deep insert backer rod into crack and counter sink at least 1/2" below primary surface. Pour the dynamic joint filler into the crack immediately after mixing and smooth out surface with a flat trowel.
