Concrete Preparation

Before coating is applied, concrete must be:

  • Dry – No wet areas
  • Clean – Contaminants removed
  • Profiled – Mechanical preparation

Mechanical preparation is the preferred method of preparing concrete for coating application. Shot-blasting or diamond grinding are acceptable methods. Use a crack chaser with a diamond blade to prepare joints and cracks prior to installation of UPC 777 Perfect Patch TG.

Mixing

The ratio of UPC 777 Perfect Patch TG is 1 to 1. That is, one part A (resin) to one part B (hardener). Mix with a paint stick, trowel, or tapers knife. Perfect Patch TG material cures quickly. Mix small batches to optimize working time.

  1. Mix equal amounts of part A and part B together for 30 seconds. Mix only the amount of material that can be applied within 1-2 minutes.
  2. Immediately apply to concrete.
  3. If mixing with sand as a mortar/slurry, mix A and B first and then add sand. Mix for another 20 seconds and apply immediately.

Application Instructions

Clean the area of debris and contaminants that would act to debond UPC 777 Perfect Patch TG ; oils, loose materials, dirt, rubber etc. Expose clean rough concrete for best results. If using a saw to cut cincrete and clean the crack, remove all of the dust from the cut out area. Cut a vertical edge, minimum 1/4" deep, around the perimeter of spall. Make sure the area is dry. Vacuum all cement dust.

Apply Perfect Patch TG with a 3" X 8" trowel or tapers knife.

Clean-up

UPC 777, while in an un-reactive state, may be cleaned up with water and degreaser. Isoprpyl alcohol or acetone may be needed once the resin begins hardening.
