My garage is a 32'x40' Pole Barn. The concrete floor is a trowel smooth surface.
Product: used two AR3505GAL-Clear and one Non slip fine grit.
I used 2 ounces of the Non Slip for each Gallon of product used.
I applied 2 coats originally using a 3/8" paint roller and because the floor soaked up so much of the product for the 3rd coat I used a 1/2" paint roller.
I feel the 1st two coats I did not use enough product because I applied it like paint to a wall and had only used 4 gallons. Hope the pictures help and thank you for a great product,
Howard
