THE SAME QUALITIES that make pumice a great abrasive also work to make pumice highly effective as a grit for non-skid and “toothy” coatings—a sponge-like stone riven with nooks, crannys and sharp glassy edges that grab and hold.
Another advantage inherent in the foamed-stone nature of Dimension Grit™ is that it binds tightly into the cured paint, primer, coating, or resin. And unlike the monolithic solidity of a sand particle, pumice is friable. Under enough force or wear, pumice tends to fracture instead of popping out, leaving some of the pumice particle bound in place to continue providing grip. The loose sharp-edged shards will tend to bite into surface coating and provide positive traction under load (which is why pumice makes a great snow and ice traction aid). Conversely, solid particles like sand, once freed from the binding substrate, add a loose layer of slippery particles to roll and slide around underfoot.
Stays in Suspension. Because of the light, frothy nature of pumice and its low specific gravity, Dimension Grit™ tends to stay in suspension (how long depends of viscosity of liquid). Heavier grits, like sand, will settle, requiring constant stirring or agitation or a last-minute sprinkle-in application right before applying..

|DIMENSION GRIT™ (BABY BITE)|
|In-suspension grip agent for giving tooth to primers (like Primus™) that prepare gypsum wall board surfaces to take thin-coat (venetian-type, like LimeStrong Artisan™) interior plasters. For paints where a subtle texture is desired while also serving as a functional filler/extender. Stir into gessos to achieve mildly texturized surface for painting.
