The present disclosure provides a method for producing detectable warnings (16) on substrate surfaces (14), which includes providing a mat (30) with a top surface (38) and a bottom surface (36) and a pattern of mat through holes (34) extending through the mat (30). The through holes (34) comprise a
The present disclosure provides a method for producing detectable warnings (16) on substrate surfaces (14), which includes providing a mat (30) with a top surface (38) and a bottom surface (36) and a pattern of mat through holes (34) extending through the mat (30). The through holes (34) comprise a lower portion (44) defining a lower mat opening (33) and an upper portion (32) defining an upper mat opening (35), wherein the upper mat opening (35) is larger in transverse dimension than the lower mat opening (33). The method further includes placing the mat (30) on a substrate surface (14), wherein the bottom surface (36) of the mat (30) is adjacent the substrate surface (14), and injecting into the mat through holes (34) a viscous substance (40) having the ability to cure into a solid. The method further includes removing the mat (30) at the appropriate time to form raised detectable warnings (16) on the substrate surface (14).

The invention claimed is: 1. A method for producing detectable warnings on substrate surfaces, comprising: (a) providing a mat with a top surface and a bottom surface, the mat having a pattern of mat through holes extending through the mat, said mat through holes comprising a lower portion defining a lower mat opening in the bottom surface of the mat and an upper portion defining an upper mat opening in the upper surface of the mat, the upper mat opening larger in transverse dimension than the lower mat opening; (b) placing the mat on a substrate surface, wherein the bottom surface of the mat is adjacent the substrate surface; (c) injecting into the mat through holes a viscous substance having the ability to cure into a solid; and (d) removing the mat at the appropriate time to allow the viscous substance to fall downwardly through the mat through holes and form raised detectable warnings on the substrate surface. 2. The method of claim 1, wherein the mat through holes are of a generally inverted frusto-conical shape. 3. The method of claim 1, wherein the upper and lower mat openings are circular in shape. 4. The method of claim 3, wherein the upper portion of the through holes curve outwardly and upwardly toward the top surface of the mat. 5. The method of claim 1, wherein the method further comprises: (a) allowing the viscous substance in the lower portion of the mat through holes to fall downwardly onto the substrate surface when the mat is removed; (b) allowing the viscous substance in the upper portion of the mat through holes to fall downwardly and inwardly through the mat through holes onto the viscous substance on the substrate surface; and (c) allowing the viscous substance to slump on the substrate surface and form detectable warnings. 6. The method of claim 1, wherein the detectable warnings in final form may be generally in the shape of a dome having a lower surface with a diameter of at least 0.9″ and no more than 1.4″, a dome upper surface with a diameter of at least 50 percent of the base diameter and no more than 65 percent of the base diameter, and a height of at least 0.2″. 7. The method of claim 1, wherein the detectable warnings are selected from shapes consisting of diamond shapes and dumbbell shapes. 8. The method of claim 1, wherein the mat through holes are arranged in a sinusoidal row, each row being in stacked relationship to another similar row. 9. The method of claim 1, wherein the viscous substance is a monomer. 10. The method of claim 1, wherein the step of preparing the viscous substance further comprises the step of combining at least one adjunct to create a viscous blend. 11. The method of claim 10, wherein the at least one adjunct comprises glass fibers, glass spheres, glass filaments, pigments, or abrasives. 12. The method of claim 1, wherein the viscous substance is selected from the group consisting of polyester, polyethylene, polyurethane, polypropylene, polymethacrylate, polystyrene, polystyrene-acrylonitrile, polyvinylchloride, vinyl chloride acetate, nylon, rayon, acetate, acetate butyrate, rubber, methylmethacrolate, and polycarbonate. 13. The method of claim 1, further comprising applying a layer of viscous material to the substrate surface and detectable warnings. 14. A method for producing detectable warnings on surfaces, comprising: (a) providing a mat with a top surface and a bottom surface, the mat having a pattern of mat through holes that are generally in the form of an inverted frusto-conical shape such that each mat through hole has a lower portion defining a lower mat opening in the bottom surface of the mat and an upper portion defining an upper mat opening in the top surface of the mat, the upper mat opening larger in transverse dimension than the lower mat opening; (b) placing the mat on a substrate surface, such that the bottom surface of the mat is adjacent the substrate surface; (c) injecting into the mat through holes a viscous substance having the ability to cure into a solid; (d) removing the mat from the substrate surface; (e) allowing the viscous substance in the lower portion of the mat through holes to fall downwardly onto the substrate surface; (f) allowing the viscous substance in the upper portion to fall downwardly and inwardly through the mat through holes and blend into the viscous substance on the substrate surface; and (g) allowing the viscous substance to slump on the substrate surface and cure to form detectable warnings. 15. The method of claim 14, wherein the detectable warnings are selected from a group consisting of circular, elongated ellipses, diamond-shaped and dumbbell-shaped. 16. The method of claim 14, wherein each detectable warning may have a transverse dimension of at least 0.9″ and no more than 1.4″ along the bottom of the detectable warning, a dome upper surface with a transverse dimension of at least 50 percent of the base diameter and no more than 65 percent of the base diameter, and a height of at least 0.2″. 17. The method of claim 14, wherein the viscous substance is a monomer. 18. The method of claim 17, wherein the viscous substance is a two-part monomer that may have a catalytic reaction. 19. The method of claim 14, further comprising applying a layer of viscous material to the substrate surface and the detectable warnings.
