Abstract: A method for increasing resistance to damage of a building wall due to wind, water, fire and seismic events including the steps of covering the wall with a fiberglass mat wherein the mat and wall are coated with a prime coat followed by a finish coat laced with cement-sand mixture. Special methods of preparing the base surface of the wall depend on the nature of the wall, be it plywood, gypsum, stucco or concrete. The system is applicable to a vertical wall or floor. Special steps are taken to augment various selected properties of the wall such as increasing shear strength and abrasion resistance.
