Description
Overview
Sikaflex Self-Leveling Sealant is a pourable, one-component polyurethane for horizontal concrete joints. It flows into a level joint and cures to an elastic seal; this gray 10.1-ounce version is not a non-sag product for vertical or sloping gaps.
Features
- Self-leveling consistency for suitable horizontal joint work.
- Moisture-cured polyurethane with movement capability.
- Can be painted with compatible coatings after the required cure and testing.
Specifications
- Color / cartridge: Gray / 10.1 fl oz
- Movement capability: ±25%
- Classification: ASTM C920, Type S, Grade P, Class 25
- Joint width: Up to 1-1/2 in.
- Joint depth: 1/4–1/2 in.; traffic areas require at least 1/2 in. depth
- Application temperature: 40–100°F
- Tack-free / final cure: Approximately 1–2 hours / 3–5 days; conditions affect timing

Applications
Seal appropriate level, horizontal joints in concrete or cementitious slabs, including driveways, garage floors, sidewalks, terraces, balconies, warehouse floors, plazas and factory or civil-engineering surfaces. The joint must contain the flowing sealant; do not use it on a slope or in a vertical opening.
Selection and Use
- Follow the specified joint geometry, generally a 2:1 width-to-depth ratio within the allowable depth limits. Use suitable closed-cell backer rod or a bond breaker to prevent three-sided adhesion.
- Manufacturer directions permit new concrete after 24 hours of curing and previously wet concrete one hour after the water source stops, with no standing water and proper preparation.
- Do not apply over asphalt or bituminous material. Keep alcohol and incompatible solvents away during cure.
- Allow at least one week before immersion or painting and test coating compatibility. Immersion conditions, including the 5 ppm chlorine limit, must follow the data sheet; tack-free does not mean ready for every service exposure.
