Metzger/McGuire Gallon Stain Prevention Film (SPF) has several chemical choices to fill joints and cover surfaces. It can be used to protect conventional concrete, colored concrete, stained concrete, tile, and other surfaces.
SPF is a water-based single component film-forming liquid intended for use in the protection of concrete slab surfaces against staining which can result from epoxy joint filler overfill. SPF is water-soluble and can be easily removed after joint filler installation is completed.
“Due to unforeseen circumstances with the shortage of raw materials, there is currently a 15% surcharge on all Metzger material.”
