Hey Ed! So our Liquid Granite epoxy runs $3.99/sqft so at 1350sqft you’re looking at $5386.50. That includes all materials and labor, tax, and we coat the stem wall up to the baseboard on every floor too. Our epoxy is twice as thick as competitors, we use twice as much chip (even compared to their full coverage), and the clear is twice as thick as well. It's also UV resistant, scratch, stain, chemical, and solvent resistant. As for prep, we don't do an acid wash, we actually diamond grind the entire floor to properly etch it and ensure that the epoxy bites into the concrete, providing the strongest bond possible. We warranty the floor against lifting and delaminating for 5 years and product is truly one of a kind, especially when you see samples in person.
