The present invention is a system of building materials with surface regions destined for joint formation that are treated with an adhesive partially comprised of a mixture of epoxy resin (96.0-99.9 parts) and hardener (4.0-0.1 parts), such that the epoxy resin/hardener mixture constitutes 50-100% of the adhesive. In an alternative embodiment, the adhesive may have epoxy resin (96.0-99.9 parts) such that the epoxy resin constitutes 45-95% of the adhesive. The remainder of the adhesive may be one or more of the following: hardeners, plasticizing agents, diluents, thickeners, fillers, colorants, opacifying agents, preservatives, and surfactants.
