Quick Overview: 
  • Excellent adhesion properties for sealers
  • Thru-and-thru black color that stays looking great
  • Very jagged surface when compared to sand


Have you ever put down a fresh coat of sealcoat, only to slip and slide all over when it rains? That's when you need to put aggregates in your sealcoat to create an anti-slip abrasive and give you maximum traction.

Most professional sealcoaters and a lot of the sealcoat manufacturers will simply use sand as the aggregate of choice because it's super cheap to get ahold of and frankly, works well enough for most sealcoat jobs. The problem with sand though is two-fold. First, sand pebbles are usually round instead of jagged. A round surface doesn't provide as good of traction as a jagged surface. Second, sand pebbles are all sorts of colors ranging from white to dark brown. When the top layer of sealcoat wears down to expose the sand, you end up with a speckled asphalt surface that usually ends up looking dark gray instead of flat black.

Our BIGA Pitch Grip Slag is a black mineral ore slag aggregate that you can mix with sealcoat sealer and a fantastic alternative to sand so you don't end up with a speckled mess of a parking lot or driveway after six months. In addition, mineral ore slags are a jagged material that juts up and out of the sealer, giving you fantastic adhesion when your asphalt surface is wet..

This sealcoat aggregate isn't just for coal tar sealers though. You can easily add it to other sealers that don't already come with aggregates such as asphalt emulsion sealers or acrylic sealers that don't already come with an aggregate.

The main group of folks who should be interested in our mineral ore slag aggregate is folks who have tried sealcoat sealers with sand and haven't been impressed. We're confident you'll like this product.

If you're looking for a bulk discount, we also offer this product as a half pallet with 18 buckets or a full pallet with 36 buckets.

Other Uses

While we market this as an aggregate for the sealcoating industry, it also makes a fantastic aggregate for paint as well. The two main downsides to using this with paint is that you'll want to roll on the paint if you mix it with paint because the aggregate will tear up paint sprayers. You can also sprinkle it on by hand after painting. The other downside is the color. Since this is charcoal black in color, as the paint wears the aggregate color will show through. If you sprinkle on top, you'll get a speckled look.

The other big industry that would use a mineral slag aggregate is the media blasting industry. If you're into sand or media blasting, this is a fantastic alternative to sand and other abrasive medias.
