N-10-20-25 POURED CONCRETE in DOVE GREY is our most popular architectural wall finish. To create this finish we trowel the mixture of Cement of Portland and aggregate on any solid surface, distress it and burnish to look like poured concrete.It looks great in bathrooms, staircases, fireplace or accent walls. Revolutionary NANO Sealer we use doesn't alter natural concrete look, but create serious protection from dirt. Can be waterproofed with matte sealer and used inside showers.
