Final Finish 
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
Application
Surface Preparation
Clean the Surface: Ensure the concrete is free from oil, grease, dust, laitance, or other contaminants. For best results, substrates that are porous or subject to very dry or hot conditions should be pre-dampened to achieve a saturated-surface-dry (SSD) state without standing water.
Mixing and Application
- Mixing Instructions: Final Finish can be mixed by hand or with a low-speed drill. Start by adding the recommended amount of water to the mixing container, followed by the Final Finish powder. For a 40 lb pail, approximately 16 pints (2.0 gallons) of water is suggested, equating to about 41% by weight. Mix for 2-3 minutes until a uniform, smooth consistency is achieved. To extend the pot-life to up to 3 hours at 72°F, cover the mixing container with a damp rag during this period. Avoid overmixing or retempering the mixture.
- Applying Final Finish: For Trowel or Sponge Float Applications: Apply pressure to force Final Finish into cracks, voids, and honey-combed areas, ensuring it spreads easily and retains moisture for easy application. For thicknesses exceeding 1/4″, consider using Overcrete for better results. For Wall Applications: Address low areas and voids with SpecPatch or Overcrete and allow to harden. Apply a thin layer of Final Finish over the entire surface, working it in with a sponge float or trowel. If necessary, a second coat may be applied before the first coat fully cures, avoiding extreme weather conditions, especially heat and wind.
Curing Process
Final Finish will achieve its full cure within 24 hours. Protect the applied material from rain or excess water until fully cured.
Packaging
Available in 15 lb pails, 40 lb bags (60 bags per pallet), and 40 lb pails (36 pails per pallet).
