Bricks and stones

When sandcarving stone such as brick, use a coarse, 80–100 grit abrasive. We have seen good results over a range of pressures (35–90 PSI), depending on the substrate and equipment. Even soft stone may require multiple passes, so use a more durable mask to prevent blowouts. Once a while, we need to use additional adhesive to keep the mask in place on the uneven surface. Also, paint-fill can help to create greater contrast.
