How to Resurface a Concrete Patio with a Decorative Concrete Overlay

This week we are going to resurface a concrete patio with a sprayed concrete overlay in a slate pattern.

The first thing we have to do is prep the concrete so that the overlay will bond to it. We do this by pressure washing the concrete. Once we removed the mold, we realized part of this patio was covered in paint, so we had to grind the concrete to remove the paint. After we finished grinding, we acid etched the concrete and pressure washed it one more time.

The next step is to apply a concrete base coat. We mix the concrete overlay and then apply it with a magic trowel on the surface.

We return the next day and apply a slate pattern to the concrete. We do this by applying strapping tape to the concrete to create a slate stencil. Then we mix our concrete overlay material and spray it directly on to the concrete. We run a trowel over the concrete on the second coat to give it a knockdown texture.

We let that material cure overnight and then we return to seal the concrete. We scrape the surface and then blow it clean before we apply the sealer. Once the concrete patio is clean we roll two coats of a solvent based clear sealer across the entire surface.

We use many different types of concrete overlay materials. A few of our favorites are Increte Systems Spray-deck, H&C Duratop, or Westcoat overlay products. We can achieve similar results with any of these brands and they all seem to hold up really well in our Virginia climate.
