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. ONE STEP resists the effects of oil and gasoline when spills are wiped up immediately.
DECK-O-SEAL ONE STEP is ideal for glazing operations and sealing joints in concrete structures. It bonds well to concrete, masonry, glass, metal and wood. It is ideally suited for applications when an expansion joint is required. NOTE: Do not paint DECK-O-SEAL.
ONE STEP is frequently used in high sloping and vertical expansion joints where a non-sag, watertight, elastomeric sealant is required. ONE STEP is ideal for use in swimming pools above the waterline, where the tile meets the pool coping. For joints that will be submerged under water, use DECK-O-SEAL 125 for horizontal applications or DECK-O-SEAL GUN GRADE for high sloped or vertical applications. All joints submerged under water must be primed with P/G PRIMER from W. R. MEADOWS.
