Chloride Test for Surface

Chloride testing is an essential step in evaluating the risk of corrosion on prepared surfaces before applying protective coatings. Soluble salts, especially chlorides, can compromise coating adhesion and lead to premature coating failure. The Bresle method is widely used for this purpose, employing a Bresle patch to isolate a defined surface area and extract soluble salts with a controlled volume of deionized water. The resulting solution is analyzed to determine chloride concentration, allowing operators to assess surface cleanliness and ensure compliance with industry standards. Reliable chloride testing helps protect structures, extend coating life, and prevent costly maintenance or failures.
