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.

Application Instructions

Clean the area of debris and contaminants that would act to debond UPC 777 Perfect Patch; 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.

Caulking Cartridge Application: Remove end cap from cartridge. Screw static mixer to top of cartridge. Place assembled cartridge into pneumatic dispensing tool for use. Extrude a small amount of material off to the side until a uniform color is achieved. Dispense under a constant uniform pressure.

Perfect Patch requires diamond grinding after it has cured. This should be performed prior to the application of any UPC system. If UPC Perfect Patch is not ground, it may be seen through the new coating system.

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.

Warranty

Universal Polymer Coatings products are warranted for one year after date of purchase. Please refer to the UPC Limited Material warranty for additional clarification.

Safety

Consult UPC 777 Perfect Patch SDS. Avoid UPC 777 contact with skin. Some individuals may be allergic to epoxy resin. Protective gloves and clothing are recommended.
