Sandblasting uses high pressure to thrust sand towards a surface to remove rust and paint along with other coatings and debris. The sharp edges of sand powerfully hit the surface and scrape the unwanted material off. Surface etching is another use for sand and blasting equipment. Forcing sand through a small, precise nozzle allows a sandblaster to create engravings on stone and other hard surfaces.
Lay a large tarp outdoors in an adequate space to accommodate the sand. If the weather does not permit a tarp outdoors, lay the tarp in a garage or similar space.
Pour the sand over the tarp and spread it out with a stiff broom or the flat side of a metal rake.
Allow the wet sand to sit in the sun until the sand dries on top. When using indoor tarps, set up space heaters to generate heat to dry the moisture present in the sand.
Turn the over using a shovel. Spread the sand evenly over the tarp after turning it to facilitate drying.
Rent a drum dryer from a tool rental store. A drum dryer constantly rotates and provides heat to remove excess moisture from sand.
Pour the sand in the drum dryer, close the door and lock the latch.
Turn the power on and allow the dryer to remove the moisture.
Wear safety glasses and a dust mask when working with sand.
Do not use space heaters in areas where combustibles are present.
