Claims11
A method of making a display, comprising the steps of:
- a) providing a concrete substrate;
- b) sweeping an area of the concrete substrate prior to placing a stencil in place on the area;
- c) providing a stencil on the concrete substrate, the stencil defining a portion of the display to be formed, the stencil including an adhesive backing covering an adhesive side of the stencil;
- d) peeling off the backing of the stencil to expose the adhesive side of the stencil, and placing the adhesive side of the stencil on the area;
- e) sandblasting a recessed portion in the concrete substrate;
- f) coloring the recessed portion;
- g) sealing the colored recessed portion;
- h) the step of sandblasting the concrete is carried out for a sufficiently long period of time that an aggregate in the concrete is exposed, so as to achieve a three dimensional look;
- and
- i) forming a recessed border with one of a die grinder and a saw equipped with a diamond blade.
