Final Finish Green Conscious Product

Rapid-hardening, polymer-modified concrete resurfacer

Final Finish is a one-component, rapid-hardening, polymer-modified, concrete resurfacing mortar, designed for smoothing, resurfacing, rubbing, and restoring concrete surfaces. This product combines a long pot life with rapid hardening to minimize waste and labor. It contains no crystalline silica, making it ideal for ultra-fine repairs. Final Finish is highly durable and suitable for all interior and exterior applications on horizontal, vertical, and overhead surfaces. It can also serve as a skim patch or trowel-down underlayment for light traffic areas up to 1/4 inch.

  • Tilt-up panels
  • Horizontal, vertical, and overhead applications
  • Concrete block
  • Pre-cast concrete
  • Interior and exterior concrete surfaces

Surface Preparation: Ensure the concrete surface is sound and free from all contaminants such as oil, grease, dust, and laitance. Pre-dampen porous or hot/dry substrates to a saturated surface dry (SSD) condition without standing water.

Mixing: Hand mix or use a low-speed drill. Start by adding the recommended water volume to a container, then gradually add the Final Finish powder. Aim for a water ratio of approximately 41% by weight, or about 16 pints (2 gallons) per 40-pound pail. Mix for 2-3 minutes until smooth. Keep the mix covered with a damp cloth to extend pot life to up to 3 hours at 72°F. Avoid overmixing or retempering.

Placement: Apply with a trowel or sponge float, using pressure to work the material into cracks, voids, and honeycombed areas. For thicknesses over 1/4 inch, use Overcrete.

Wall Application: Level low areas and fill voids with SpecPatch or Overcrete before applying Final Finish. Apply a thin coat across the surface, working it in with a sponge float or trowel. A second coat can be applied before the first is fully cured. Avoid extreme weather conditions during application.

Curing: Final Finish cures in 24 hours. Protect it from rain or excessive moisture until fully cured.


Available in 15 lb pails, 40 lb bags (60 bags per pallet), and 40 lb pails (36 pails per pallet).
