Abstract
This disclosure relates to a method of manufacturing a sign or similar article by providing a wooden substrate having an upper surface; providing a laminate formed by several plies including a ply of sandblast-resistant material, an adhesive, a ply of vinyl, another adhesive and a carrier ply; cutting the laminate to form a template of a desired configuration and applying the template to the upper surface of the substrate, sandblasting the upper surface of the substrate which removes an upper surface strata thereof which is exposed to the sandblast material while unexposed surface strata is uneffected, and thereafter removing the sandblast-resistant ply from the vinyl ply forms a permanent upper covering/indicia/design atop the selected area of the substrate unaffected by the sandblast material.
Claims6
A sandblast stencil formed as a laminate for adherence to a substrate which is to be sandblasted and including as part of the laminate a sign/logo/design ply which remains affixed to the substrate after the substrate has been sandblasted, said sandblast stencil comprising a resilient laminate for sandblasting a substrate, said laminate including a sandblast resist ply and a sign/logo/design ply, first adhesive means for bonding said sandblast resist ply to said sign/logo/design ply, second adhesive means for bonding said sign/logo/design ply to a substrate prior to sandblasting thereof, said resist ply being in overlying protecting relationship to said sign/logo/design ply and being constructed of material resistive to damage during sandblasting whereby said sign/logo/design ply is protected, and the bond strength of said second adhesive means is stronger than the bond strength of said first adhesive means whereby at the completion of a sandblasting operation said sandblast resist ply can be removed from said sign/logo/design ply along the first adhesive means while the second adhesive means maintains said sign/logo/design ply affixed to the sandblasted substrate.
