Blockade Concrete Sealer, a penetrating, water-based repellant sealer and finish from Enviro-Solutions, is designed specifically for concrete floors. Blockade was recently used on the concrete floors of a Canadian sports arena that sees more than 10,000 people traverse them monthly.
"We applied four coats of Blockade," Swish Maintenance sales representative Lori Thornton said. "By the third coat a shine appeared, and by the fourth the floor was glossing like new."
