Invisible contaminants like soluble salts can cause coatings to fail prematurely, even on a freshly blasted surface. Chlorides, sulfates, and other residues draw moisture through the coating, leading to blistering, rust, and costly rework. Our Surface Contamination Risk Calculator evaluates the likelihood of contamination based on environmental conditions, abrasive source, and blasting method. Use it to identify high-risk situations, determine when salt testing is necessary, and plan effective remediation steps—so your surface prep meets industry standards and your coatings perform as intended.
