Weibao Board is produced from a mixture of cement, silica sand, special cellulose fibres and selected fillers to impart durability, toughness and moisture resistance. Weibao mixture is compressed to enhance high strength and durability of board that is capable of heavy duty usage. It is then cured by and autoclaving process whereby the ingredients are reacted together under the effects of moisture or heat. Weibao will not rot or support fungal growth and is unaffected by sunlight or steam. The board does not contain any soluble ingredients or free alkali which could be dissolved by moisture or condensation and causing unsightly marks. If exposed to moistuer, Weibao Board will completely recover on drying out, with no permanent loss of strength. The board will not degrade with time and within normal applications, the life of the product is limited only by the durability of the supporting structure and materials used in fastening. Weibao Board is natural light grey in color and has a high quality top sanded smooth finish on one side and a slightly textured reverse.
