For most jobs: aluminium silicate, 0.2–0.5 mm. It takes paint and rust off wood, metal, brick and stone. We sell it as BLSTR Grit, and you can also buy it from other suppliers. Delicate wood or heavy industrial coatings? Compare the options and plan your job below.
Grit, also called abrasive or blasting media, is what the BLSTR sander fires at the surface. It drops into the centre of the spinning ceramic blast wheel and is thrown out at high speed. Every grain that hits chips off a tiny bit of paint, rust or dirt, and millions of grains strip the surface clean.
It is not ordinary sand. Beach or play sand is too round and too soft to cut well, it holds moisture and clogs, and dry quartz sand gives off fine dust you should not breathe. Blasting grit is a dry, sharp-edged material, sieved to one grain size, made for the job.
Softer grit is gentler on the surface; harder grit can cut faster. Tap an abrasive for what it is best for and where to buy it.

Coating thickness is part of this job.
Actual usage may vary with layer thickness, the type of coating and the material underneath.
Steel grit is for experienced/professional users. Because of its high density, flow behaviour differs significantly from mineral abrasives. Use only tested particle sizes, avoid overfeeding, and make sure the blast wheel is clear before restarting.
New to the BLSTR sander? Your first jobs will take longer than these times, and use a bit more grit. Finding the right speed setting, distance and movement takes some practice. It's a fun learning curve, and once you have the feel, results come much faster.
We recommend treating grit as single-use: plan for fresh grit on every job.
