Has anyone had experience with this approach? The surface is rolled and then a spray gun is used to broadcast the nonskid onto the wet paint. I wonder if you can get a more even surface than using a shaker?
Covering it thoroughly with a shaker and then brooming it off after it dries will get you a great surface. If you want to go faster, use a leaf blower set on high and held close to the surface about one hour after you roll and dust, then immediately paint your second coat. Assuming you are using awlgrip with a recommended ratio in a normal temperature shop.
