Deck-O-Seal ONE STEP is a single component, non-sagging, polysulfide-based sealing compound for caulking swimming pool joints and structures that are subject to movement due to temperature change.
This caulking is ideal for sealing all joints in concrete structures wherever a permanent water-tight seal is required. It is ideal for use in swimming pools above the waterline, where the tile meets the pool coping. It also bonds well to masonry, glass, metal, and wood. For joints that will be submerged under water, use two part Deck-O-Seal (pourable grade) for horizontal applications. All joints submerged under water must be primed with Sealtight P/G Primer.
ONE STEP is pre-mixed, ready-to-use, in a self-contained 11 oz. cartridge. ONE STEP is not paintable. DO NOT apply paint over surfaces sealed with Deck-O-Seal products.
