Base Detecting Paint

Base Detecting Paint



ON GUARD™ Base Detecting Paint is a white latex base coating specially formulated to be an alkaline (base) indicator for solutions with a pH 10 or greater.  The cured film of ON GUARD will respond to alkalinity, turning the coating from a bright white to a deep, brilliant blue, immediately. ON GUARD provides an immediate visual indication of a spill or leak at extremely small quantities.  This is an exceptional latex coating with superior durability and easy application.

Use ON GUARD over primer as a top coat.  The use of ON GUARD White Primer #315 or a quality latex primer with rust inhibitor is required.  ON GUARD may be used over an existing latex coating if the user is ensured that the existing coating is stable and the surface is clean, dry, rust, dust, oil and contamination free.  If the sub coating is less than one year old, or has a slick finish, adhesion may be a problem.  In such instances, use a transition coating or scuff-sand overly smooth surfaces.  Applying ON GUARD over an oil-based paint will require the use of a transition coating to ensure inner-coat adhesion.
