Is this the product?

I have not used this product but the term “dryfall” caught my attention. Not a bad thing, it just speaks to product durability. I wouldn’t use it alone on surfaces that are touched. The binder in this product is very weak.
I’ve often mixed 1 part heavy binder product (porch and floor enamel/polycrylic/stays clear/etc) to 2 or 3 parts discount paint. Do more tests to see what works best for you.
It’s possible that spray application is recommended because brush or roller application would void the ability to dryfall. You can’t sweep up big splotches of paint, just the dust.
