Rust-Oleum's ThermaKrete urethane concrete coating provides protection for concrete in harsh industrial environments. Suitable for use in applications where concrete floors are subjected to dramatic temperature fluctuations or thermal shock, the coating expands and contracts to resist cracking. Available in 3/16 in. or 1/4 in., the coating withstands caustic washdowns, heavy traffic, high impact, abrasion, chemicals and standing water contamination, says the company. It can be applied on an entire facility floor or for patch repairs.
