Coverage Calculator
How much Rubberseal do you need?
Enter your square footage and target thickness, and the calculator estimates the gallons your project needs. Plan on about 32 sq ft per gallon at 40 mils; build to at least 60 mils dry film where water will stand.
Rough surfaces like old concrete or weathered masonry absorb more material — order extra for textured substrates, and remember multiple coats build the membrane.
