Soft Tread Metal Primer is a water based Acrylic, low VOC coating that gives superior rust inhibition and corrosion protection when applied to bare metal substrates. In addition to corrosion protection, Soft Tread Metal Primer provides great adhesion to metal surfaces and is an important component of the Soft Tread or Safe Tread Coating System. Apply as a base coat for Soft Tread or Safe Tread anti-slip coatings without harmful solvent use or the need for highly complex application equipment. Protects against corrosion and oxidation on Steel, Aluminum, Copper, prepared Galvanized and other metal surfaces.
