Polyurethane Sealants - Sikaflex® Textured Sealant

One-component, all purpose, polyurethane sealant

Sikaflex® Textured Sealant is a moisture-cured, 1-component, polyurethane-based, non-sag elastomeric sealant capable of ±25 % joint movement. Meets Federal specification TT-S-00230C, Type II Class A. Meets ASTM C-920, Type S, Grade NS, Class 25.

• Excellent adhesion - bonds to most construction materials without a primer.
• Textured appearance blends well to rough or stucco type surfaces.
• Hides imperfections from tooling that a smooth sealant does not.
• Excellent resistance to aging, weathering.
• Non-staining.
• Paintable with water-, oil- and rubber-based paints.
• High elasticity - cures to a tough, durable, flexible consistency with exceptional cut and tear-resistance.
• Stress relaxation.
• Urethane-based; suggested by EPA for radon reduction.

Usage

• Designed for all types of joints where maximum depth of sealant will not exceed 1/2 inch.
• Suitable for vertical and horizontal joints; readily placeable at 40°F (4°C).
• Has many applications as an elastic sealant between materials with dissimilar coefficients of expansion.

Ideal for:

• Weatherproofing of joints between brickwork, blockwork, masonry, wood and concrete or metal frames.
• Joints in walls, balconies, around window or door frames.
• Expansion joints.

Application Steps

SUBSTRATE PREPARATION

Clean all surfaces. Joint walls must be sound, clean, dry, frost free, and free of oil and grease and any other contaminants. A roughened surface will also enhance bond Install bond breaker tape or backer rod to prevent bond at base of joint.

Priming

Priming is not usually necessary. Most substrates only require priming if testing indicates a need or where sealant will be subjected to water immersion after cure. Consult Sikaflex Primer Technical Data Sheet or Technical Service for additional information on priming.
