SEALANT CNCRT MSNRY GRY 101OZ 91065

Description

Overview

Sikaflex Self-Leveling Sealant (91065) is designed for horizontal concrete and masonry joint sealing applications requiring a self-leveling, permanently flexible polyurethane sealant.

Technical Features

• Single-component polyurethane formula: Requires no mixing, simplifying application and reducing the risk of incorrect ratios on the job site.
• Self-leveling grade (ASTM C-920 Grade P): Flows into horizontal joints under gravity to fill voids uniformly without tooling.
• Class 25 joint movement capability (ASTM C-920): Accommodates 25% joint movement, maintaining a durable seal in substrates subject to thermal expansion and contraction.
• Permanently flexible: Resists cracking and de-bonding over the service life of the joint, reducing the need for frequent resealing.
• Moisture resistant: Maintains adhesion and seal integrity in wet or damp conditions, suitable for exposed outdoor environments.
• Mildew resistant: Inhibits mildew growth on the cured sealant surface, supporting long-term appearance and hygiene in high-humidity areas.
• Paintable surface: Accepts paint over cured sealant, allowing color-matching to surrounding concrete or masonry finishes.
• Cartridge packaging (10.1 fl oz): Compatible with standard caulking guns for controlled dispensing and reduced material waste.
• Meets Federal Specification TT-S-00230C Type 1 Class A: Confirms compliance with government-grade performance standards for elastomeric sealants.

Applications

• Horizontal concrete control joints and expansion joints in flatwork, driveways, and sidewalks
• Masonry joint sealing in block walls, brick, and concrete structures
• Indoor and outdoor sealing applications where a self-leveling, gray-colored finish is required
• Projects specifying ASTM C-920 or Federal Specification TT-S-00230C compliant sealants
