How to Use
Clean all surfaces. Joint walls must be sound, clean, dry, frost-free, and free of oil and
grease and any other contaminants. Install bond breaker tape or backer rod to prevent
bond at base of joint.
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 informa-
tion on priming.
Recommended application temperatures: 40°-100°F (4°-38°C). For cold weather applica-
tion, condition units at approximately 70°F (21°C); remove prior to using.
For best performance, Sikaflex Mortat Fix 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 seal-
ant, 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 as required. Joint dimen-
sion should allow for ¼ inch minimum and ½ inch maximum thickness for sealant. Proper
design is 2:1 width to depth ratio.
When over-coating with water, oil and rubber based paints, compatibility and adhesion
Avoid exposure to high levels of chlorine. (Maximum continuous level is 5ppm of chlo-
Maximum depth of sealant must not exceed ½ in.; minimum depth is ¼ in.
Maximum expansion and contraction should not exceed 25% of average joint width.
Do not cure in the presence of curing silicone sealants.
Avoid contact with alcohol and other solvent cleaners during cure.
Do not apply when moisture-vapor-transmission condition exists from the substrate as
Use opened cartridges the same day.
When applying sealant, avoid air-entrapment.
Since system is moisture-cured, permit sufficient exposure to air.
White color tends to yellow slightly when exposed to ultraviolet rays.
Light colors can yellow slightly if exposed to direct gas fired heating elements prior to
The ultimate performance of Sikaflex Mortar Fix depends on good joint design and
Do not tool with detergent or soap solutions.
Contains xylene; avoid breathing vapors. Use with adequate ventilation.
NIOSH approved respirator is needed if PELs are exceeded.
In case of skin contact, wash thoroughly with soap and water. For eye contact, flush imme-
diately with plenty of water for at least 15 minutes; contact physician. Wash clothing before
re-use. Discard contaminated shoes.
Uncured material can be removed with approved solvent. Cured material can only be
removed mechanically. For spillage, collect, absorb, and dispose of in accordance with
current, applicable local, state, and federal regulations.
