particularly asphalt saturants that are used to waterproof asbestos-cement or similar types of building boards.
Building boards composed of asbestos fiber and Portland cement when combined under pressure into a homogeneous dense mass have high strength and great durability. Building boards being exposed to damp or wet weather for any substantial periods of time, there is a tendency of the boards to absorb sufflcient moisture to 1 cause the board .to'swell or creep. Therefore,
substantial openings are required at the joints new edges of the board are exposed when cutting. or breaking the board into smaller-pieces.
According to the present invention, it has been found that improved saturation of the boards with bitumen may be achieved at room temperatures and normal pressures by the application of asphalt in cutback form. The percentage of asphalt in the cutback determines the penetration of the saturant in the building boards .com-
of this type may be made in different forms for posed of asbestos fiber and Portland cement, that various purposes, that is, they may be made in is, when a saturant containing inthe neighborflat sheets and used as side walls, both indoor hood of 35 to 40% of asphalt dissolved in a soland outdoor. They may be corrugated and used vent naphtha having a gravity varying from 28 as roofing and sidings. There is one disadvanto 48 A. P. I., a kauri butanol solvent power tage in using boards of this type, that is, upon varying from 53 to 82 and boiling points between 168 F. and 450 F. is used according to this invention, an optimum penetration is obtained. The following table is used to illustrate the depth to which the saturant penetrates in asbestoscement boards:
