There is disclosed a resin-coated overlay for bonding to solid substrates, and which imparts improved waterproofing and chemical resistance to the resulting resin-coated overlaid solid substrate. Depending upon the desired end use of resin-coated overlaid solid substrate, the resin-coating may be modified to impart desirable surface features and/or characteristics. For example, additives such as waxes, oils, silicones, fluorocarbons and fatty acid compounds may be used to promote the release of concrete from forms made of solid substrates overlaid with the resin-coated overlays of the present invention. Moreover, resin-coated overlaid solid substrates may be produced having a surface which is suitable for painting and which accepts application of various tape products. Other modifications are disclosed which can be used to gain desirable cure speed, cost, and chemical/mechanical properties in the resin-coating. In addition to variations on the resin-coated overlay, related methods are also disclosed for the production of resin-coated overlays and resin-coated overlaid solid substrates.
A resin-coated overlay comprising a medium density overlay having a partially-cured resin-coating on at least a portion of a surface of the medium density overlay, wherein the partially-cured resin coating comprises a wax in an amount ranging from about 0.5% to 45% by weight and a phenolic thermosetting resin, and wherein the medium density overlay comprises an unbleached kraft paper.
