Quartz System Calculator
Calculate the total quartz aggregate needed for a single or double broadcast floor system, including bags to order.
Calculate Your Quartz Aggregate and Bags
Choose a single or double broadcast, enter your floor area, and the tool works out the weight of quartz aggregate you'll get through at full saturation — then converts it to the number of bags to order in your chosen bag size.
Broadcast System
Full saturation broadcast — single or double coat system.
Bags to Order
Defaults to the 50 lb Torginol bag — change it to match your supplier.
Enter a floor area to see quartz quantities.
The broadcast rate defaults to a full saturation rate of 0.5 lb/ft² (2.44 kg/m²) per coat — the industry / Torginol full-broadcast figure, editable above. Actual consumption varies by aggregate size, surface texture, and broadcast technique. Always confirm the rate with your product supplier before ordering.
How the Quartz System Calculator Works
- Select your unit — square meters or square feet
- Enter the total floor area to be coated
- Choose Single Broadcast for a standard one-coat system, or Double Broadcast for high-traffic or outdoor areas requiring two broadcast coats
- Adjust the waste allowance if needed — 10% is standard for most jobs
- Enter your bag size to get an instant bags-to-order count

Frequently Asked Questions
What is a quartz broadcast floor system?
A quartz broadcast system is a floor coating where quartz aggregate is broadcast into a wet epoxy or polyaspartic base coat and pushed to saturation. Once cured, excess quartz is swept off and a clear seal coat is applied over the top. The result is a hard-wearing, slip-resistant surface used in commercial kitchens, warehouses, pool surrounds, and outdoor areas.
What is the difference between single and double broadcast?
A single broadcast system applies one epoxy coat with quartz broadcast to saturation, followed by a clear seal coat. A double broadcast system applies two epoxy coats, each with a full quartz broadcast, before sealing. Double broadcast produces a thicker, more durable profile and is recommended for heavy traffic areas, outdoor exposure, and anywhere additional chemical or abrasion resistance is required.
What coverage rate does the calculator use?
The broadcast rate defaults to a full saturation rate of 0.5 lb/ft² (2.44 kg/m²) per coat — the industry / Torginol full-broadcast figure for quartz thrown to refusal — and it is editable, so you can match your own product data sheet. A double broadcast doubles this to 1.0 lb/ft² (4.88 kg/m²) for two coats combined.
What quartz mesh size should I use?
The most common sizes are #20 mesh (coarser, more aggressive texture) and #30 mesh (finer, smoother profile). #20 mesh is standard for most commercial and industrial applications. #30 mesh is preferred for food service areas or where a finer finish is required. The broadcast rate is the same for both — mesh size affects texture and slip resistance, not quantity.
Why add a waste allowance?
When broadcasting quartz, material is lost at edges, corners, and any overspray beyond the floor boundary. Aggregate also varies slightly in density between bags and broadcast technique. A 10% waste allowance is standard for most jobs. Tight areas with lots of edges or difficult access may warrant 15%.
Important Notes
- Broadcast rate defaults to a full saturation 0.5 lb/ft² (2.44 kg/m²) per coat and is editable — confirm with your supplier if using non-standard aggregate sizes
- Double broadcast doubles the quartz quantity and requires two separate epoxy base coats
- Always sweep off excess cured quartz before applying the seal coat — loose aggregate will prevent proper adhesion
- Common bag sizes are 22.7 kg (50 lb) and 18 kg (40 lb) — confirm with your supplier before ordering
- Order a small overage (5–10%) beyond the calculated amount to account for touch-ups and any variation in broadcast coverage
