Surface Prep

• Surface must be clean and reasonably dry.
• All crack repair should have taken place prior to pressure washing, scarifying, grinding, or shot blasting.
• Cut new control joints as required to prevent cracks transferring through the overlay.
• Pressure-wash all dust and latents from the surface to ensure a clean surface.
• If high temperatures are imminent, the substrate may be misted with water immediately before the installation to cool the concrete.

Mixing

• Each bag of Micro-Tek Micro-Topping powder requires 8-10 quarts of water.
• Do not add additional polymers!
• Pour 3/4 of the 8-10 quarts of water into an empty 5-gallon bucket.
• Add the entire contents of the powder and blend briefly with a drill-powered mixer to wet out the material.
• Wait 5-10 minutes, and then add the remaining water and mix at medium speed until the material is homogenous and free of all lumps.
• A mix similar to the consistency of buttermilk is ideal.

Application

• Micro-Tek SG MUST be applied over Micro-Tek RG or G-100 Pro Series Grout.
  *Refer to appropriate TDS for installation instructions for these products.
• Pour 1/4 to 1/3 of the mix onto the surface.
• At this point, the material may be applied to large areas using a squeegee to spread the material and finished by hand or "funny trowel," or simply spread and troweled by hand. In either case, a thin coating is recommended.
• Material builds over 1/8" are discouraged.
• Let Micro-Tek Micro-Topping dry completely and sand the surface between layers, if desired.
• Remove all dust and debris.
• For a smooth, power-troweled look, trowel the material near to final thickness and then flat trowel again after a few minutes much like you would regular concrete.
• Sweat and broom finishes can be accomplished in much the same manner.
• Concrete Coatings, Inc. Micro-Tek SG Micro-Topping should be applied prior to staining, sealing, and waxing.

Staining

If the surface is to be acid stained, surface MUST be sanded, and applying a light mist of water is recommended immediately before stain application using a plastic pump sprayer.

Sealing

• Although Micro-Tek Micro-Toppings are very durable, they must be sealed to maintain their integrity.
• Allow the overlay to cure for a minimum of 24 hours and protect the surface with SuperSeal 2000, GemKote 400, GemKote 350, or GemKote 100.

Maintenance

• The sealed surface should be inspected periodically for areas of thin or traffic-worn sealer.
• Worn areas may be resealed as needed.
• A thorough cleaning is recommended prior to resealing to ensure debris or contaminants are not embedded in the subsequent sealer coat(s).
