The present invention is characterized as methods for fixedly depositing solidified protrusions on to a surface, and products thereof so as to create a detectible warning whereby the tactile and visual characteristics of the detectible warnings contrast with the tactile and visual characteristics of surrounding surfaces. To create such a detectible warning, a mask in the form of a resilient mat is perforated with a plurality of apertures so as to form a repeating pattern. Each aperture acts as a mold of a protrusion having predetermined dimensions. To enhance the functionality of the protrusions, each protrusion has a generally inclined peripheral surface and rounded peripheral surface to substrate and peripheral surface to upper surface interfaces. The mat is placed in contact with the substrate on which a detectible warning is desired. A blend is created from a curable viscous substance and one or more of the following: reinforcing elements, reflective elements, pigments, or abrasives. The blend is then worked into the apertures whereupon it begins to solidify. After the blend becomes semi-stable, the mat is removed and the protrusions are allowed to fully cure.
