Formulated specifically for the unique climate in the Northwest United States and available exclusively from Masons Supply Company. Free of silicones, resins and waxes. Panels will lift clean and free of resin staining. Organic compounds in it react with the free limes in the concrete, producing gels that form a water impermeable barrier. The water impermeable barrier restricts mix water (needed for hydration) from being sucked into the casting slab. The resulting downside surface of the panel will be stronger and have a more uniform appearance. Application : Provides a clean easy lift for tilt-up and lift slab concrete construction. Prevents bonding of masonry and concrete droppings from overhead pour areas. Applicable Standards : Meets or exceeds Federal EPA VOC requirements.
