The deck joint is where the pool coping and patio meet. Many times an expandable self-leveling compound is used to make a smooth transition between the two surfaces. Over time this material will shrink and crack. Replacing it involves removing the old material and cleaning the joint. An adhesive epoxy primer is applied to the edges to create the strongest bond possible between the deck and self-leveling compound. Either sand or backer rod is placed in the joint and then the compound is carefully poured into the crack to seal the two spaces together. Our two-part, polysulfide-based joint sealant is a premium-grade, pourable, self-leveling sealant. It is a non-staining sealant that cures to a firm, flexible, tear-resistant rubber. Our deck sealer also has outstanding resistance to most chemicals, to all weather conditions, aging, and shrinkage. Deck sealant is used for caulking and sealing concrete joints that are prone to movement to provide a firm, flexible, weather-tight seal. It is ideal for sealing joints on swimming pool decks. Provides a permanent and uniform watertight seal. Prevents uncontrolled cracking by allowing expansion and contraction during temperature changes. Stays flexible and won’t become brittle or crack due to ultraviolet exposure. Resists abrasion, weathering, and moisture—elevated temperatures will not cause discoloration. Not affected by pool chemicals. Retains joint soundness in service once it’s cured and can be stretched or compressed up to 25%.
