What is the price for anti-slip quartz aggregate broadcast on an Ottawa shop floor?

Quartz aggregate broadcast systems are one of the best choices for a commercial shop floor in Ottawa, and for good reason — they deliver exceptional slip resistance, outstanding durability, and a surface that holds up to heavy foot traffic, equipment, and the constant moisture and grit tracked in from an Ottawa winter. Here is what you can expect to pay and what goes into a proper installation.

What a Quartz Broadcast System Costs in Ottawa

For a commercial shop floor, quartz broadcast epoxy systems typically run between $8 and $14 per square foot installed in the Ottawa market for 2025 to 2026. The final number depends on several factors: the current condition of your concrete, how much surface preparation is required, the thickness of the epoxy base coat, and whether you are adding a urethane or polyaspartic topcoat over the quartz layer. A fully built-out system — base coat, full broadcast quartz, grout coat, and a chemical-resistant urethane topcoat — lands toward the higher end of that range. For a typical 1,000 square foot shop floor, you are looking at roughly $8,000 to $14,000 professionally installed, before any concrete repair work.

If your concrete has cracks, spalling, oil contamination, or previous coating failures (all extremely common in Ottawa shops), add $2 to $5 per square foot for surface preparation and repairs. Diamond grinding or shot blasting is non-negotiable on a commercial floor — without it, even the best quartz system will delaminate. Never let a contractor skip this step, regardless of what they tell you about the floor looking clean.

The quartz aggregate itself is typically a double broadcast, meaning the coloured quartz granules are thrown into the wet epoxy until the surface is fully saturated, then a second grout coat of epoxy fills the voids between the granules before a final topcoat is applied. This creates a surface profile that is both extremely durable and highly slip-resistant — a critical safety feature in any shop environment where water, oil, or cutting fluids may be present.

Ottawa's climate adds complexity to commercial shop floor projects. If your shop is heated year-round, you have flexibility on timing. If it is an unheated or partially heated space, application must happen when the slab temperature is reliably above 10 degrees Celsius — ideally between 15 and 25 degrees. Concrete holds cold much longer than air does, so even a warm spring day does not guarantee a warm slab. A good contractor will check substrate temperature with an infrared thermometer before mixing any product.

Moisture testing is essential before any coating goes down. Ottawa's water table and seasonal snowmelt push vapour through concrete slabs at rates that can destroy a coating from below. A calcium chloride test or in-situ relative humidity probe test should be performed and documented before application. If moisture vapour emission rates exceed 3 pounds per 1,000 square feet per 24 hours, a moisture-mitigating primer is required — this adds cost but prevents catastrophic failure down the road.

From a permit standpoint, applying a coating to an existing shop floor generally does not require a building permit in Ottawa. However, if your project involves significant concrete replacement, structural changes, or is part of a larger commercial renovation, confirm with City of Ottawa Building Code Services by calling 3-1-1.

For next steps, get a minimum of three written quotes and ask each contractor specifically about their surface preparation method, the epoxy solids content they are using, and what topcoat they recommend for your specific shop use.
