ON GUARD™ Acid Detecting Paint is a durable, industrial coating with a unique acid-sensitive component, which changes color (golden yellow to brilliant red) when exposed to acid or acid vapors pH 3 or lower. The reaction of ON GUARD to acids pH 3 or lower is instantaneous.

Use ON GUARD over primer as a topcoat. The use of ON GUARD White Primer #315 is strongly recommended. This product may cause lifting of inferior sub coats. Surfaces must be clean, dry, rust, dust, oil, and contamination free. ON GUARD may be used over existing paint if the user is assured that the sub coating is stable and the surface is clean, dry, rust, dust, oil, and contamination free.
