How to use this product data

EpoxyCalc currently catalogs this system for garage floor. Floor products are compared using manufacturer-published coverage data rather than casting depth. The listed mix ratio is 2:1 by volume. Always measure using the method stated by the manufacturer because weight and volume ratios are not automatically interchangeable.

This page is a planning reference, not a substitute for the current technical data sheet. Re-check the manufacturer guidance before a large pour, especially when temperature, total mass or project geometry is near a published limit. Product availability and prices can also change after the verification date shown above.

Need the exact resin and hardener amounts for this product's published ratio? Use the resin and hardener ratio calculator and keep the manufacturer's weight / volume basis unchanged.

Verified notes

The manufacturer publishes a 2:1 mix ratio by volume, about 70 minutes working time, and a 3–7 day cure window.
Coverage depends strongly on the decorative application method; EpoxyCalc stores melded-marble and dirty-pour coverage separately instead of averaging them.
For concrete, Stone Coat instructs users to prepare the floor and use its moisture-seal primer before the midcoat; a compatible top coat is part of the complete flooring system.
Verified public prices are stored for the 1.5 gal kit and the separate 15 gal project kit; the 3 gal variant is intentionally left unpriced until its current public price is independently verified.
