thin concrete overlay coating
SureCrete’s Micro Topping is a single component thin concrete overlay that is a self-bonding cement based, for interior concrete surfaces. Micro Topping was designed to yield an exceptionally smooth tight-troweled finish that can provide a new “blank canvas” for decorative concrete floors. It may also be placed vertically on interior walls, creating the look of Venetian plaster. Application is accomplished by trowel or “magic trowel.” Micro Topping thin concrete overlay is prepared with gray cement or white cement that may accept Color Packs.

When restoring an old concrete surface, or even possibly some freshly poured ones, inevitably there is some discoloration and cracks or possibly even large patching that has to be done. These blemishes on your concrete slab can easily show through any decorative stains or sealers applied to your finished surface. With Micro Topping thin concrete overlay, your newly created “blank canvas” can alleviate these issues, giving you a nice clean surface to begin creating your new custom floor designs. While it may take a professionally trained hand to tightly trowel a perfectly flat surface using Micro Topping, many of the designs you can create using this product can be achieved by even the untrained Do it yourself (DIY) homeowner.

How Do You Apply SureCrete Micro Topping Thin Concrete Overlay Mix?

We’ll show you the best way to apply Micro Topping:

  1. Any surface receiving a cementitious coating must be clean, cured, sound and profiled. See our Surface Preparation products for more information on accomplishing this
  2. Make sure that temperatures will remain between 50 and 90 degrees Fahrenheit and there will be no precipitation in the applied areas for a 48 hour period following application.
  3. Add 5 quarts water per 40 lb bag to 5 gal bucket and mix in any color desired for integral coloring of Micro Topping
  4. Slowly introduce Micro Topping while continuously mixing and mix for a minimum of 1 minute once all product has been emptied into container. Scrape the sides of the bucket to make sure there are no “dry pockets” that didn’t get mixed properly.
  5. Mist the surface of the concrete with water, and pour out a generous amount of Micro Topping thin concrete overlay.
  6. Tightly trowel or squeegee the product over your entire application area.
  7. If you need a second coat of Micro Topping thin concrete overlay, simply wait until the surface is properly cured – between 2-6 hours. Then simply apply the same as first coat!
  8. Once the surface is dry to the touch, it can accept stains and secondary colorants at this point, and is also ready to receive a sealer. Typical indoor applications would utilize a polyurethane or polyaspartic sealer from our DuraKote line of products.

Frequently Asked Questions About Micro Topping Thin Concrete Overlay:

the substrate you’re working with.

section for a few pointers. If nothing else, feel free to attend one of our
local training opportunities throughout the country.

While mixing in large batches can be done, it is important to never mix up
more than can be applied within a 45 minute time frame.

Why are there different colors and cracks shadowing through my Micro Topping Thin Concrete Overlay

Micro Topping is applied at such a thin rate that imperfections will likely
show through in the first coat of the product, this would be a case where a
second coat would likely be desired.
