Spray Down Re-Surfacing or Cova-Crete is a cost effective and popular alternative to replacing an old slab of concrete.
Spray on Resurfacing
It is a very similar look to Stencilled Concrete but is done after the concrete has set. Many different looks can be achieved by a variety of different patterns and techniques. This technique is also great where you want to lay new concrete next to an old slab and you want it to match. The new concrete can be laid and finished and then they can both be Re-Surfaced to look uniform.
The product used in this method is similar with the Spray Down Re-Surfacing, but it is trowelled down giving the floor a different effect. This is very popular indoors because a marble look and a smoother finish can be achieved.
