A dual-action, non-yellowing compound for exterior, broomed concrete, Pencure OTC is clear, transparent, and easy to apply. The compound has been formulated to simultaneously form a membrane to cure the slab while also penetrating the surface to help reduce water and salt penetration. It imparts a low-gloss, satin appearance for driveways, patios and parking lots. Pencure OTC minimizes crazing and shrinking cracks common to improperly cured or uncured concrete. It meets ASTM C309-11 Standard Specification for Liquid Membrane-Forming Compounds for Curing Concrete Class A and B specifications. — W.R. Meadows, Hampshire, Ill., (847) 214-2100; www.wrmeadows.com
