Soluble salts are a major cause of coating failures, responsible for around 64% of cases. They are non-visible contaminants that can accelerate corrosion. Using Chlor-Rid soluble salt remover and testing kits helps ensure surfaces are properly cleaned, preventing premature coating failures and extending asset life at low cost. Engineering and project staff should update specifications and implement best practices to test for and remove soluble salts.

- 2. Soluble Salts Are Everywhere But Should Not Be Allowed on Certain Parts of YOUR Assets One key statistic from trade association, SSPC, revealed that 80% of all coating failures were attributable to bad surface preparation. A separate survey said that 80% of bad surface preparation was a consequence of soluble salts. This equates to the notion that 64% or two-thirds of all coating failures are related to avoidable soluble salt contamination.
- 3. Nature of the Beast—What are Soluble Salts Ionic contaminants (like dust particles that interfere with adhesion, accelerate corrosion, cause blistering, and allow disbondment of protective coatings such as insulation or fire resistant coatings) Water soluble inorganic compounds (humidity triggers the electrolyte portion of the “corrosion cell” that is the mechanism for corrosion) Primarily chlorides, sulfates, and nitrates (that convert to hydrochloric, sulfuric, and nitric acids on metals which explains why rust “corrodes” metals) Non-visible contaminants (shown in detail on next slide which illustrates why ion specific and real test kits are required for assessment before and after remediation) Can bond electrochemically to the metal substrate (which is why a chemical is needed to remediate and not just mechanical abrasion)
- 4. Soluble Salts Are Non-Visible at One Millionth the Size of a Sand Particle 40 mil The “gold” standard in protective coatings standards is the white metal blast “appearance” for surface cleanliness. However, that is based on visible to the naked eye assessment. Here we see proof that this serious contaminant makes what is “pretty”, not so pretty!!!

- 6. Why use CHLOR RID to test for Soluble Salts Field proven for more than two decades, premeasured elements of the test kits accurately and quickly reveal the ion specific contamination levels. Different salts have different corrosivities with different allowable thresholds Testing after cleaning assures the proper level of cleanliness is attained. Consumable components assure no cross-contamination Major scientific laboratories buy and use our test kits including Federal Highway Authority for their reliability in replicating results. Specifications specifically call out for our CSN test kit for chlorides, sulfates, and nitrates for different authorities including US Navy Facilities Command and US Army Corps of Engineers. http://www.wbdg.org/ccb/DOD/UFGS/UFGS%2009%2097%2013.27.pdf
- 7. Why Use CHLOR RID Soluble Salt Remover Assures proper surface preparation and is viewed as Best Management Practice Helps prevent premature coating failures and works with all coating systems Extends life of coating system with significant economic advantages (next slide) Added to potable wash water to remove soluble salts from the surfaces with normal equipment. Offers DUAL FUNCTION CHEMISTRY that 1. Chelates the metal cations and 2. Sequesters the salt anions Biodegradable (when tested for LDL, lethal dose limit, it was not tested in the 1 to 100 ratio as intended to be used, but accidentally was tested at FULL concentrated strength, and still passed.) Cost effective at about ten cents per sq ft plus a second dime approximation for test kits, that favorably compares with other preparation costs which do not remove soluble salts as readily and cost $/sq ft.
- 8. “Prior to 1995, it is estimated that at least 3 out of 4 contractors suffered major failures during projects or shortly thereafter. Most coatings did not survive more than 5 to 7 years. Now with changes, including CHLOR*RID, we have an approximately 70 to 90% reduction in lifecycle costs, have reduced premature coating failures and increased service life.” --source, NAVFAC
- 9. How You Can Help Preserve Your Assets and Optimize Your Construction Dollars Engineering staff (internal and outsourced) can update specifications for surface preparation sections and concrete repairs (inspired by successful private industry, SSPC, NACE, AREMA, US D.O.D.,) Project staff on projects can implement Best Management Practices of testing for and removing soluble salts (various references worldwide) Maintenance staff periodically maintenance wash surfaces to remove surface salts (inspired by various Transportation Departments and professional practices, e.g W VA DOT and W VA Pkwy. Auth.)
