Flex 515304 Self-leveling Sealant, Polyurethane, 10-oz.

Sikaflex Self-Leveling Sealant is a single-component, premium-grade polyurethane sealant designed to seal horizontal expansion joints in concrete and cementitious surfaces. This self-leveling formula flows into gaps and cures to a smooth, flexible finish without requiring manual tooling, making it an ideal choice for both professional contractors and homeowners tackling concrete repair projects.

Perfect for driveways, garages, sidewalks, balconies, and other horizontal concrete applications, this sealant provides reliable waterproofing and excellent adhesion. Its rapid curing capacity means full strength is reached sooner, allowing the sealed surface to be used quickly. The sealant can be applied to new concrete 24 hours after the initial cure, or to concrete just 1 hour after rainfall, offering flexibility in application timing.
