This practice covers detailed information on the handling, installation, and proper use of chemical-resistant sulfur mortar. The sulfur mortar shall be stored in unopened containers and in a clean, dry place to prevent contamination of the product. Sulfur mortar must be heated and molten in order to be used. Adequate ventilation should be provided whether sulfur mortars are used. All surfaces which molten sulfur mortar will contact must be dry to prevent splattering. Horizontal joints may be formed by resting each brick or tile on three spacers which are placed in a triangular pattern. The floor shall be given a skim coat of sulfur mortar prior to installing brick or tile. The chemical resistance of sulfur mortars shall be determined.
