Description

Calcium silicate is a synthetic mineral produced from cupola furnaces melting cast iron.

Finner grades can be compared to the use of silica sand that has now been made illegal to blast with so is a good alternative, due to its soft nature. Making it useful for open nozzle blasting of stone, brick and wood.

Calcium Silicate is a versatile expendable abrasive used for shotblasting a wide variety of substrates. By using different grades then the profile achieved can be changed, medium grade will at 100 psi at the nozzle give a minimum of 75 microns on mild steel.

Example – for cleaning grafiti of brick work

We suggest that one 25kg bag will do roughly 1msq..

The blasting nozzle ideally needs to be 3x the size of the largest particle of grit for the abrasive to flow freely.
