A press caul suitable for embossing wood panels to produce textured wood surface designs is described. This caul is made by casting liquid, epoxy resin filled with aluminum powder against a panel surface bearing a textured design and applying sufficient heat to cure at least partially. The product caul may then be separated for use. If the desired degree of curing is not reached in the molding step, the caul may be baked. This ensures the permanency of the applied relief. In a further optional embodiment, the resin may contain a plurality of sheets of embedded fiberglass fabric to provide reinforcement.

A method for forming a high-strength, temperature resistant caul capable of embossing a textured surface onto a preformed panel, overlaid with a resin impregnated paper, at temperatures of from 270°to 320°F. and pressures of from 175 to 250 psi, comprising the steps of: forming a mold from a textured hardboard panel; applying a sealer to the panel; coating the sealed panel with a release agent; preheating an aluminum filled epoxy resin to approximately 80°-90°F., said resin having a viscosity no higher than about 100,000 centipoise at room temperature; impregnating at least one layer of glass fiber cloth with said preheated resin admixed with a catalyst, the ratio of resin to catalyst being approximately 17.5 to 1 respectively; placing said layer of catalyzed resin impregnated glass fiber cloth in said mold; pouring additional preheated catalyzed resin onto said mold containing said catalyzed resin impregnated fiberglass cloth layer; partially curing the caul formed from the catalyzed resin for approximately 4 to 5 hours at a temperature of about 150°F., such that the caul assumes the relief configuration of the textured panel; and baking the caul for about 8 hours at a temperature of approximately 350°F. such that the caul is fully cured and the configuration of the textured panel assumed by the caul is permanently maintained.
