A quartz broadcast system is a floor coating where colored quartz sand is spread into wet resin, usually in two layers. It builds a thick, textured, slip-resistant surface. It’s common in commercial kitchens, locker rooms, and other wet areas. A clear topcoat seals the quartz in place and makes the floor easier to clean.
How a Quartz Broadcast Floor Is Installed
“Broadcast” just means scattering by hand, the way you’d spread grass seed across a lawn. The crew throws colored quartz sand over wet resin until the surface is covered. Once it hardens, they sweep off the loose sand and repeat.
A typical job goes like this:
- Grind the concrete so the coating has a rough surface to grip.
- Roll on a resin base coat and broadcast quartz into it until it’s fully covered.
- Let it cure, sweep up the extra sand, and do a second resin coat and broadcast.
- Seal it all with one or two clear topcoats.
Systems that repeat the broadcast step are called double broadcast floors. That second layer adds thickness and a deeper, more even color. Manufacturers describe the finished system as quartz grains broadcast into epoxy resin and sealed with a clear coat.
Why Choose a Quartz Broadcast Floor
A quartz broadcast floor is one of the thicker resin floors you can put down. That build gives it a few strengths:
- Grip when wet. The sand leaves a texture your shoes can hold, even with water on the floor.
- Toughness. Thick layers stand up to carts, dropped pans, and daily scrubbing.
- A seamless surface. No grout lines or seams means fewer spots for dirt and germs to hide.
- Hidden wear. The speckled color blend hides scuffs and dirt between cleanings.
The clear topcoat controls how rough the floor feels. More topcoat fills in the texture and makes it smoother and easier to mop. Less topcoat leaves more grip. A contractor can tune this room by room, such as rougher by a sink and smoother in a hallway.
Quartz Broadcast vs. Flake Floors
Both systems scatter something into wet resin, but they’re built for different spaces. A full flake floor uses paper-thin vinyl chips and is the usual pick for home garages. A quartz broadcast floor uses hard mineral sand, goes on thicker, and has more natural texture, which is why it shows up in commercial kitchens and locker rooms.
For a home, quartz broadcast is worth a look in a mudroom, basement bathroom, or garage where you want maximum grip. For more on how resin floors compare, see our guide to concrete floor coatings.
Quartz Broadcast FAQ
Is quartz good for flooring?
Yes, for spaces that get wet or see heavy use. The quartz grains are very hard, so the floor keeps its grip and color for years. With routine care, a quartz floor can last 10 years or more.
What are the disadvantages of quartz broadcast floors?
They cost more than a single coat of epoxy because they use more material and more labor, with curing time between layers. The texture is rougher on bare feet and takes a bit more effort to mop. Like any resin floor, it also depends on good prep and a dry slab to stay bonded.
What is the difference between single and double broadcast?
A single broadcast floor has one layer of quartz sand, while a double broadcast floor repeats the resin and sand step. The double version is thicker, more durable, and has a richer color. Most commercial kitchens and locker rooms use double broadcast.
