Diatomite is a sedimentary rock with many uses. It is made up of the siliceous skeletal remains of diatoms, which are tiny single-celled algae. Diatomite is crushed into a powder known as "diatomaceous earth". It is lightweight, porous, relatively inert, and has a small particle size along with a large surface area.For priming and decorating with paint, texture or wallcovering, follow manufacturer’s directions for materials used. All surfaces, including applied joint compound, must be thoroughly dry, dust free and not glossy before decorating.

It occurs in extensive beds associated with other evaporite minerals, particularly in Permian and Triassic sedimentary formations; it is deposited from ocean brine, followed by anhydrite and halite. Rock salt & rock gypsum often occur together in evaporitic successions. Rock gypsum is composed of the mineral gypsum (CaSO 4 ·2H 2 O - hydrous calcium sulfate). Heating of gypsum or rock gypsum drives off the water, leaving only calcium sulfate behind (the mineral anhydrite). Adding water to anhydrite results in the formation of gypsum again.Call our Technical Support team at 800-874-4968 (Monday-Friday, 7:30 am - 4 pm Central).
