1.Sulfur mortar capping compound shall be as per ASTM C 617 recommendation.
2.Safety Caution: The primary hazard in handling powdered Sulfur is that Sulfur DUST suspended in air ignites easily and produce explosive forces in confined areas. Ignition sources can be heat, friction, pyrophoric Sulfur and internally generated static electricity. An initial small explosion can create subsequent large explosion if the building area contains dusty powder residue on overhead surfaces such as rafters or trusses. A Sulfur dust will produce Sulfur Dioxide, a TOXIC gas. I prefer to use another material with less dangerous.
