I’m looking for insight on Aqua Resin. We’ve got 22 4′ tall x 9″ deep foam letters that we need to hard coat for exterior use and abuse (think children running around). We’re looking for a super smooth, clean finish. They were used last year without a hard coat, so they’re already in rough shape. They have a coat of paint on them. After doing research and pricing, I’ve mostly settled on Aqua Resin with Aqua Veil. I’ve used it once before, but it was a little soft after it cured. Is there a better product? Operator error? Epsilon Pro is more expensive and toxic, but we could go that route. I’ve got 540 square feet of foam to coat, so according to the calculator on Rosebrand I should need about 20 gallons of Aqua Resin for 1/16″ coating, or a little less than 15 gallons of Epsilon Pro.
I’m intensely allergic to Styrospray now, plus it’s reliant on humidity to cure, so I strongly prefer to stay away from that option.
We use Aqua Resin here over top of fiberglass fabric and it’s fantastic. Our actors run and jump all over these knee-walls and while yeah, they definitely can crack, I’m always surprised at how nice they stay throughout the course of the run. We’ll lay down the fabric, then use the aqua resin to smooth and keep it in place. Maybe try that!
