The document discusses techniques for applying stencils to precast concrete panels to create the appearance of brick or stone masonry using products from Artcrete. The stenciling process involves laying out and embedding fiberboard stencils on freshly finished concrete and applying a color hardener to replicate various brick patterns. Stencils can also be applied to cured precast panels using an adhesive backing and topcoat. This stenciling technique provides a cost-effective way to achieve a masonry look on precast structures without special tools or training.
