Stencilling is typically done with a wax impregnated paper in a roll that is pre-cut to patterns that can be selected from a catalogue (stone, brick, etc.).
The stencil is then wet set into the concrete when the concrete is first laid. Then colour hardener is cast over the concrete, troweled in, release agent is applied, and it is textured. The result is a realistic tile stone or brick look that is extremely durable due to the colour hardener product. Viccon Constructions is your trusted Local Concreter.
