Sikaflex® Mortar Fix
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.
- Urethane-based; suggested by EPA for radon reduction.
Usage
- Designed for all types of joints where maximum depth of sealant will not exceed inch.
- Suitable for vertical and horizontal joints; readily placeable at 4°C (40°F).
- 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.

FAQ
Do not tool with detergent or soap solutions.
Light colours can yellow slightly if exposed to direct gas-fired heating elements prior to the formation of initial skin.
Avoid contact with alcohol and other solvent cleaners during cure.
Maximum expansion and contraction should not exceed 25 % of the average joint width.
Maximum depth of sealant must not exceed 13 mm (1/2 in); minimum depth is 6 mm (1/4 in).
Avoid exposure to high levels of chlorine. (Maximum continuous level is 5 ppm of chlorine.)
Sikaflex® Mortar Fix is paintable with water-, oil- and rubber-based paints but when over-coating with water, oil and rubber-based paints, compatibility and adhesion testing is essential.
For cold weather application, condition units at approximately +21 °C (70 °F). For best performance, Sikaflex® Mortar Fix should be gunned into joint when joint slot is at the mid-point of its designed expansion and contraction. Place nozzle of the gun into bottom of the joint and fill entire joint. Keep the nozzle in the sealant, continue 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 6 mm (1/4 in) minimum and 13 mm (1/2 in) maximum thickness for sealant. Proper design is 2:1 width to depth ratio.
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® Primers Product Data Sheet or contact Sika Canada for additional information on priming.
Sikaflex® Mortar Fix has a Limestone colour, but the white colour tends to yellow slightly when exposed to ultraviolet rays.
Sikaflex® Mortar Fix has a good resistance to water, diluted acids, and diluted alkalis. Contact Sika Canada for specific data.
The drying time is about 5 hours. And the final cure is 7 days.
Do not cure in the presence of curing silicone sealants, and since the system is moisture-cured, permit sufficient exposure to air.
After curing, Sikaflex® Mortar Fix has a high elasticity to a tough, durable, flexible consistency with exceptional cut and tear resistance.
Recommended application temperatures: +4 °C to +38 °C (40 °F to 100 °F). Sealant should be installed when joint is at the mid-range of its anticipated movement.
One (1) 300 mL (10.1 US fl. oz) cartridge seals 3.72 linear meters (12.2 li ft) of 13 mm x 6 mm (1/2 in x 1/4 in) joint. The ultimate performance of Sikaflex® Mortar Fix depends on good joint design and proper application with joint surfaces properly prepared.
