$0.00 / TUBE
Sikaflex® Mortar Fix 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. Meets ASTM C 920, Type S, Grade NS.
• 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
Clean all surfaces. Joint walls must be sound, clean, dry, frostfree, and free of oil and grease and any other contaminants. Install bond breaker tape or backer rod to prevent bond at base of joint.
For best performance, Sikaflex Textured Sealant should be gunned into joint when joint slot is at mid-point of its designed expansion and contraction. Place nozzle of gun into bottom of the joint and fill entire joint. Keep the nozzle in the sealant, continue on with a steady flow of sealant preceding the nozzle to avoid air entrapment. Avoid overlapping of sealant to eliminate entrapment of air. Tool sealant to ensure full contact with joint walls and remove air entrapment. Joint dimension should allow for 0.75 inch minimum and 0.5 inch maximum thickness for sealant. Proper design is 2:1 width to depth ratio.
