Abstract
Cement wallboards and methods for their preparation are disclosed. The wallboards comprise two scrim layers and one mat layer. The wallboards have a smooth surface, are strong, lightweight, and easy to score and snap. Tiles can be readily adhered to the boards. The wallboards can be used in general commercial and residential construction, and are particularly attractive for use in high water/moisture areas such as bathrooms and shower enclosures.
