"Cover it up" - Concrete floor covering

July 2010 Job of the Month - This was a small concrete floor covering project we did in Irving, Tx. We used our standard thinfinish overlay material for the concrete floor covering to get rid of the exposed aggregate that the floor has. The exposed aggregate (where you can see small stones sticking out of the concrete) was not what they were looking for so we proposed a trowel down to cover it up. The trowel down, being a concrete floor covering, buries the exposed aggregate under a new, thin layer of concrete.

  Our Irving project started with a power wash to get rid of all contaminants followed by a very light grinding of the floor to roughen up the stones a little bit so that the new concrete floor covering would stick to them. As with all concrete floor coverings, proper floor prep is very important so that you don't have problems with delamination, which is where the overlay peels away from the floor.

Our Irving homeowners knew exactly how they wanted the floor to be scored. They were looking for a certain size stone pattern and wanted a very thin grout line (the spacing between the stones). We offer a few options for grout lines. This particular pattern is flowing. The grout line is almost the exact same width very little variation which creates an effect in which the stones almost meld to each other. We also have a thicker grout line that is more irregular and more jagged depending on what you like. The irregular width grout lines are more realistic as normally stones are not cut to fit exactly together like a jigsaw puzzle.

When it came to color for the concrete floor covering, our Irving homeowners also had a specific color scheme in mind. As you can see in the pictures, there are three main colors that were applied to different stones formed by our trowel down process. They were looking for colors that would complement with the brick facade of their home. It really came out looking nice.

Concrete floor coverings work really well to cover up exposed aggregate because concrete floor coverings completely cover the exposed aggregate as long as the coating goes on thick enough.
   
 
   
Usually, when we are placing it over exposed aggregate we recommend putting down a trowel down or stamped overlay because these are thicker coatings that help hide the stone profile below. Skim coat overlays usually go down too thin and some of the stone texture can show through. That isn't necessarily a bad thing; it just depends on what you are willing to see. Concrete floor coverings can create just about any decorative effect you would like for your floors, depending on the result you desire.
