Sika Sikaflex SL 1 – Limestone – 30oz Cartridge
Sikaflex SL 1 is a single-component, self-leveling polyurethane sealant designed for horizontal joints in concrete floors, decks, and other high-traffic surfaces. It cures by reacting with atmospheric moisture to form a durable, flexible elastomeric seal. With ±35% movement capability and excellent adhesion to concrete and metal, this non-priming sealant installs easily and resists abrasion, puncture, and weather exposure. Its smooth finish and ability to self-level make it ideal for expansion and control joints where clean appearance and performance are both essential.
