Concrete Coatings Microtek Smooth-Grade Gray Concrete Overlay - 40 lb


About

Micro-Tek Micro-Topping is a single-component polymerized thin-section decorative cementitious coating system commonly used on countertops or floors where an acid stain is desired, when the concrete itself is too abused for a pristine surface. Tight, flat surfaces are easily produced in a fraction of the time it may take with standard grouts.

    Instructions

    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).
