Micro-Topping is a thin, flexible layer that is designed to bond to concrete. But the cement-like material also works with wood, plastic or metal. MicroTopping can be used for interior or exterior projects, on vertical or horizontal surfaces, and provides a durable coating that protects the underlying material in wet conditions.


A variety of color options and combinations allows unique designs that can be installed directly on bare, hardened concrete. The finished application is only as thin as a credit card. Micro-Top can be used on smooth concrete or printed on floors, walls and concrete countertops. Let us see how you can do concrete microtopping yourself.

Things you will need

  • Trowel or a 6-inch spatula
  • Rollers

Preparation of the Concrete

  • Clean the dust and debris from the concrete. Vacuum the surface completely to remove all loose material.
  • Use a degreasing detergent to remove all traces of grease and oil.
  • Wash away the residue and allow it to dry completely. 
  • Scrape, grind or sand any foreign material that protrudes from the floor to create a solid flat surface. 
  • Clean up any debris created in this process.
  • Fill the cracks and chips by installing evenly semi-rigid elastomeric crack filler with a wide squeegee.

Applying the Micro-Top Finish

  1. Mark any design or pattern you want to use on bare concrete with a marker. Label the color to use for each area, creating a paint-by-number pattern directly on the concrete surface.
  2. You can create any color or pattern design you want.
  3. Pour a small amount of micro-Top base coat onto a prepared floor section. It is spread over the coverage area in a thin sheet with a spatula or a spatula. Continue this process until all areas are covered. Wait until this coat is dry to the touch.
  4. Apply the acrylic sealant to the whole Micro-Top system with a brush or paint roller. Let this finish dry completely before allowing traffic to the surface.

Suggestions & Warnings

  • Use the Bomanite epoxy primer under the base layer if the original concrete is prone to water penetration from below.
  • Protect the application in a high layer of micro-top from water spray to prevent permanent white fading in the final finish.
  • Read the instructions of all manufacturers completely before the start project.
  • Sandblasting and grinding the entire surface is not necessary unless necessary to create a particular effect.
