Patch Pro is a specially formulated slurry mix comprised of white cement, polymer, and other high-performance additives, designed to fill voids and imperfections during the casting process of GFRZ Pro. This advanced cementitious formula offers minimal shrinkage, making it ideal for addressing everything from fine pinholes to larger surface voids. Patch Pro achieves sufficient hardness for sanding or polishing typically within 24 hours, depending on environmental conditions and the water-to-mix ratio.

Just add water! Approximately 3 parts powder to 1 part water by volume.

Note: Patch Pro does not contain any sand or fine aggregates and is meant to match the white color of the GFRZ Pro mix. If pigmenting to match colored concrete, an exact match can be difficult. The goal is to be within the natural color variation exhibited in the concrete. It is best to always conduct a test first if close color matching is important.
