Plaster Sand is almost like the same stuff you find at the beach but much cleaner. This refined (washed) sand has many different uses.
Plaster Sand not only can be used to make plaster but it can also be used in a cement/sand/gravel mix to make cement. Some contractors even use it to set pavers. Got holes or low spots in your lawn? Add some sand to the low spots and the grass will eventually grow right through it.
