How to Size a Complete Flake Floor System
Base coat, flake, and topcoat in one takeoff — why the three layers use completely different coverage rates, and how to avoid the most common ordering mistakes.
A flake floor is three layers — base coat, flake, and topcoat — and each one has its own coverage rate and pack size. The Flake Flooring System Calculator sizes all three from a single floor measurement, so you get one takeoff instead of running three calculators separately and losing track of which rate belongs to which layer.
How to read the inputs
Floor Size
- One number drives all three layers — measure it once with the Square Meters / Square Feet Calculator, then reuse it here
Coverage Rates
- Three separate numbers, one per layer, each pulled from that specific product’s TDS — don’t reuse one layer’s rate for another
Pack Sizes
- The kit or box size you order in for each layer — this is what determines how the quantity rounds up to a real order
Quantities vs. Kits & Boxes to Order
- The calculator shows both the exact amount needed and the rounded-up amount to actually order — always order the rounded figure
Worked example
A 500 ft² floor, using the default coverage rates: the base coat needs 500 ÷ 130 = 3.85 gal, which rounds up to 2 kits (6 gal) in 3-gallon kits. The flake needs 500 ÷ 7 = 71.4 lb, which rounds up to 2 boxes (80 lb) in 40 lb boxes. The topcoat needs exactly 500 ÷ 100 = 5 gal — but 2-gallon kits don’t divide evenly into 5, so it still rounds up to 3 kits (6 gal), not 2.
Try it with your own floor
Enter your floor size and adjust each layer’s coverage rate to match your specific products’ TDS.
Full result gives quantities and kits or boxes to order for all three layers.
Open the live calculator →Common mistakes
- Using the flake broadcast rate as if it were the base coat or topcoat rate — they’re measured in completely different units (weight vs. volume)
- Forgetting a spec that calls for two topcoat passes — this calculator computes one layer, so double the topcoat result if your job needs two coats
- Not confirming each layer’s coverage rate against its own product’s TDS — the pre-filled numbers are typical defaults, not guarantees
- Rounding a layer down to save budget instead of up — even a small shortfall on the base coat can leave bare patches under the flake
Frequently Asked Questions
Does this account for two topcoat passes?
No — the calculator computes one topcoat layer by default. If your spec calls for two coats, double the topcoat result (or run the calculator a second time) before ordering.
Why is the flake coverage rate so different from the base coat and topcoat rates?
Flake is measured by weight spread over an area (lb or kg), while the liquid base coat and topcoat are measured by volume spread over an area (gal or L). They’re different units measuring different things — don’t compare the numbers directly.
Are the pre-filled coverage rates accurate for my product?
They’re typical defaults, not guarantees. Always confirm each layer’s coverage rate against that specific product’s Technical Data Sheet before ordering, especially for less common formulations.
Should I order exactly what the calculator says?
Order the rounded-up kit and box counts the calculator already gives you, not the raw decimal quantity — that rounding is built in. Consider a small extra surplus on top for spills, touch-ups, or repairs.
