L.M. Scofield Co. has introduced Scofield Formula One Guard-S Concentrate, a penetrating, solvent-borne acrylic concentrate that is diluted with acetone by the end user and applied to interior architectural or ground and polished floors. Guard-S Concentrate is a VOC-compliant treatment that fills the near-surface voids in interior concrete floors, providing a measure of protection against water and many staining materials such as ketchup, mustard, red wine, vinegar, motor oil and antifreeze. It also increases the reflectivity (or gloss) of architectural or ground and polished concrete floors. Guard-S Concentrate is a component of Scofield’s Interior Polished Concrete System. ? www.scofield.com
