How much does a quartz broadcast aggregate cost per bag from Ottawa flooring suppliers?

Quartz broadcast aggregate in Ottawa typically costs between $45 and $85 per 50-pound bag from commercial flooring suppliers, with coverage ranging from 150 to 300 square feet per bag depending on broadcast density. The wide price range reflects differences in quartz grade, colour selection, and supplier markup, with specialty colours and finer mesh sizes commanding premium pricing.

Understanding Quartz Broadcast Systems

Quartz broadcast aggregate serves as both a decorative element and functional component in high-performance epoxy systems. Unlike vinyl flake chips, quartz provides superior durability and slip resistance, making it the preferred choice for commercial garages, workshops, and areas subject to heavy traffic or chemical exposure. The quartz is broadcast into wet epoxy at specific rates — light broadcast uses 0.3 to 0.5 pounds per square foot, medium broadcast uses 0.5 to 0.8 pounds per square foot, and full broadcast uses 0.8 to 1.2 pounds per square foot for maximum durability.

Ottawa suppliers stock quartz in mesh sizes from 12/20 (coarser) to 30/60 (finer), with 16/30 mesh being most common for residential garage applications. Coarser quartz provides more aggressive slip resistance but requires thicker topcoat systems to encapsulate properly. Finer quartz creates smoother finishes but may not provide adequate texture for wet conditions common in Ottawa garages during winter months.

The total system cost for a quartz broadcast floor runs $10 to $16 per square foot installed in Ottawa, including base epoxy, quartz aggregate, and polyurethane or polyaspartic topcoat. A standard two-car garage requires 2 to 4 bags of quartz depending on broadcast density, adding $90 to $340 in material costs alone. Professional contractors typically mark up quartz aggregate 30 to 50 percent above wholesale pricing.

Climate considerations are critical for quartz broadcast timing — the aggregate must be applied while the base epoxy remains tacky but not wet, requiring precise temperature and humidity control. Ottawa's spring and fall seasons provide optimal conditions, while summer heat can accelerate epoxy cure times and winter cold can prevent proper mechanical bond between quartz and base coat.

For homeowners planning quartz broadcast systems, professional installation is strongly recommended due to the technical requirements for proper broadcast rates, timing, and topcoat application.
