Surface Preparation: Surfaces must be dry and clean, and free of any contaminants before application (dirt, dust, oils, grease, or solvents should not be present). PolyFill’s adhesion and performance is directly related to how thoroughly the surface is prepared. Before applying, all cracks should be sanded/grinded thoroughly, and brushed with a hard brush, and chips or loose concrete debris should be removed. Clean off all dirt and dust with a blower or use a vacuum machine to leave surface completely clean and dry. It is recommended to test product in an obscure area to ensure desired results for adhesion and finish. Coverage is approximately 200-300 linear feet per half gallon kit to fill 1/8" x 1/8" cracks but will depend on porosity of the substrate and shape of the cracks.

Mixing Instructions: Pour all of Part B directly into the Part A container and mix for 2-3 minutes with a spatula or slow RPM mixer/drill. Avoid creating air bubbles. It is recommended to mix and use the entire kit at one time as parts A and B are pre-weighed to ease controlling the mixing ratios.

How to Apply: To apply, simply pour mixed PolyFill directly into the crack or apply with spatula, putty knife, or trowel. Note: PolyFill is fast curing and will harden within 15-20 minutes, so it is recommended to apply at once over the whole crack area  to allow for good penetration and leveling over the entire crack. Apply PolyFill leaving an excess or small dome over the crack, so when it hardens, it can be sanded down flat and level. For deep cracks, use a spatula to push down PolyFill mixture, making sure enough PolyFill has been added to completely fill all spaces and gaps. If a second application is needed to fill the crack, apply within an hour of the first application. After one hour, any excess filler can be removed by sanding or grinding to achieve a flat, even surface that is ready to be coated. Note: It is the sole responsibility of the applicator to determine whether PolyFill is appropriate for the job.
