DECK-O-SEAL ONE STEP is a single-component, non-sag, elastomeric, polysulfide-based sealing compound used for caulking joints in structures that are subject to movement caused by temperature changes. DECK-O-SEAL ONE STEP is designed for glazing operations and sealing joints in concrete structures when an expansion joint is required or in high sloping and vertical applications. ONE STEP is also designed for use in swimming pools above the waterline, where the tile meets the pool coping. It bonds well to concrete, masonry, glass, metal and wood. ONE STEP may help contribute to LEED credits for low-emitting or regional materials. www.wrmeadows.com
