Chloride Absorption (Salt Absorption)
CreteDefender™ virtually eliminates the threat of salt. Chloride (salt) absorption in normal concrete averages 3.4%. In testes conducted by the H.C. Nutting Company, a leading independent testing laboratory, chloride (salt) absorption for concrete treated with CreteDefender was 0.056% — a decrease of more than 99%! Not surprisingly, Nutting classified the results for concrete treated with CreteDefender as “Excellent”.
Tests of CreteDefender were performed in accordance with the Modified EPA Method 300.0. Test samples were extracted from concrete that had been exposed to 100+ freeze-thaw cycles in accordance with ASTM C-672. CreteDefender was applied to the samples at a rate of 100 square feet per gallon per application, with two applications, 8 hours apart. Samples were cured at least 24 hours prior to testing.
