How much any coating covers depends on two things:
- How thick you want the finished product to be
- What the percentage of solids (amount remaining after the liquid dries or cures) is
All our coatings (except some of the epoxy floor coatings) are 100% solids, so what you apply in the way of thickness is what you get. Unlike paint (which is mostly to color and provide basic protection from the elements), our coatings are also designed to be able to endure impact or abrasion protection in addition to basic weather or conditions protection. They are generally applied thicker than paint, but that is entirely dependent on your specific needs.
A truck bed liner application is recommended at 63 mils, koi pond at 35 – 45 mils, general purpose and water proofing at about 20 mils. The formula to determine how many gallons required (if using 100% solids) is: “sq. ft. total / (1604 / mil height)”. Using 20 mils as an example, at 1100 sq. ft, this coating would be: 1100 / 80.2 or 13.72 gallons.
Most coatings (and ALL single part coatings) are not 100% solids. They lose volume and shrink as they dry. In general, most of these type coatings are about 55% – 65% solids. To compare these coatings by volume, just divide the gallons required using 100% solids by the % solids of your coating. As an example, if a coating is 57% solids, you would require 24.07 gallons for the same coverage (13.72 / .57). It all depends on how thick you want to apply the coating as to how much coverage you will get, but if any single part product says they get say 200 sq. ft of coverage, you can expect about 330+ sq. ft coverage at the same mil height using our Seal Tite or Spray Lining and Coatings brand products.
