Abstract
A masonry stencil for masking preselected mortar patterns on a masonry surface and an associated method for coloring or staining a masonry surface. The stencil comprises a latticework structure including an open framework of strips defining a pattern corresponding to the desired or the pre-existing mortar pattern of the masonry, and defining open spaces through which a coloring medium can be applied to the masonry surface. The stencil further comprises a gasket secured to the under surface of the latticework structure for sealably engaging the masonry surface. In accordance with the method of the present invention the masonry stencil is placed on the masonry surface so as to mask the desired mortar pattern or an existing mortar pattern, and a coloring medium is applied to the unmasked surface area exposed by the open spaces of the stencil. The stencil is then removed leaving the mortar pattern uncolored.
