Disclosed is a coating composition suitable for coating onto a wall or other substrate to yield a dry-erase coating, The composition may be prepared by reacting an excess amount of an aminosilane with a carbonate, an epoxy alcohol, or both in aqueous media to yield a silylurethane, and/or a silylamino polyol. In some approaches, the compositions and/or methods may further include an epoxysilane, and allowing the epoxysilane to react with the aminosilane to yield an aminodisilane. This reaction will result in a coating composition that comprises one of a silylurethane, a silylamino polyol, or both, and the aminodisilane. The aqueous mixture of the silylurethane, the silylamino polyol, or both, and the aminodisilane together constitute a coating composition that, upon curing, forms a dry-erase coating.
