#1 Patch any spalled areas, and apply a smooth layer of grout. This layer will become the grout line of the final product, so it needs to have pigment added depending on what the customer chooses. In this example, it is white.
#2 Lay stencil over the entire area.
#3 Spray a colored grout mix over the entire area. We typically apply two coats, and we trowel over the second coat.
#4 Clean and apply sealer.
