Metallic Epoxy Material Calculator

Calculate the epoxy volumes and kits for every coat in a metallic floor system — base coat, metallic coat, and top coat.

Calculate Your Full Metallic Epoxy System

Enter your floor size and the coverage rate for each layer. The calculator sizes the whole metallic system in one go — base coat (epoxy), metallic color coat, and clear top coat — and returns the gallons required, rounded up to the kits you need to order.

Units
The area you're coating. The rates below are pre-filled with typical values — adjust to match your products.

Coverage Rates

How far each layer spreads.

From your epoxy's data sheet (TDS). Higher number = the product spreads further.

Pack Sizes

The kit sizes you order in.

Enter a floor size to calculate the metallic epoxy system.

Coverage rates are estimates. Actual usage varies with substrate porosity, application method, film thickness, and the specific products used. Always confirm coverage and kit sizes against each product's Technical Data Sheet (TDS) before ordering.

How the Metallic Epoxy Material Calculator Works

  1. Enter the floor size in square feet (or switch to metric for square meters)
  2. Set the base coat (epoxy) coverage in sqft per gallon — 160 is a typical default
  3. Set the metallic color coat coverage in sqft per gallon — 100 is a typical default
  4. Set the clear top coat coverage in sqft per gallon — 250 is a typical default
  5. Adjust the kit sizes on the right to match the pack sizes you order in
  6. Read the gallons required for each layer, plus the kits to order, and copy the results

Frequently Asked Questions

What coverage rates should I use?

The defaults — 160 sqft per gallon for the base epoxy, 100 sqft per gallon for the metallic color coat, and 250 sqft per gallon for the clear top coat — are typical industry figures. Your actual rates depend on the specific products, film thickness, and substrate. The metallic color coat is applied as a full-bodied build coat so it spreads less far, while a thin clear seal coat covers much more area per gallon. Always confirm against each product's Technical Data Sheet (TDS) before ordering.

Does this include the metallic pigment?

No — this calculator sizes the liquid epoxy and seal coat by volume. Metallic pigment is added to the metallic coat at the loading rate on your product's data sheet (typically 50–100 g per liter of mixed epoxy), so once you know the metallic-coat gallons you can work out the powder separately. Many metallic epoxies also ship pre-pigmented, in which case no loose powder is needed.

Why does the calculator round up to whole kits?

Epoxy and seal coats are sold in pre-measured kits with a fixed mix ratio. You cannot split a kit and keep the correct Part A to Part B ratio, so the calculator always rounds up to make sure you have enough material to finish each layer.

Can I skip the base coat?

Yes — if you are using a separate primer or a self-priming metallic epoxy, set the base coat coverage high enough that it contributes little, or simply ignore the base coat result. Applying a solid base coat first does improve opacity and gives a more consistent final color, so most systems include one.

What if each coat uses a different kit size?

Set each layer's kit size independently on the right. Metallic systems often use a larger base-coat kit, a smaller metallic kit, and a separate seal-coat kit — enter the real pack size for each and the calculator rounds each layer to its own kit count.

Important Notes

  • Coverage rates are estimates — porous or rough concrete typically needs more base and seal coat than smooth, prepared surfaces
  • The metallic color coat is a full-bodied build coat, so it typically spreads less far than the base or the thin clear top coat — adjust each rate to match your product
  • Each layer rounds up to whole kits at the kit size you enter — partial kits cannot be returned, so the rounded figure is your order quantity
  • Metallic pigment is sized separately from this tool — use the metallic-coat gallons and your product's loading rate
  • Always verify coverage rates and kit sizes against each product's Technical Data Sheet before placing your order
