This traffi c marking paint is not recommended for brush or
roller application.
If the striping machine is used with waterborne paint, care
must be taken to prevent contamination of the paint types.
Thinning and cleanup: Thinning should not normally be
required. Additional solvent could raise the intended VOC,
and may slow dry time or promote bleeding on asphalt
surfaces.
Clean up with Xylene, Toluene, or MEK.
If specifi c application equipment is not listed above, equivalent
equipment may be substituted.
