APPLICATION INSTRUCTIONS
SUBSTRATE PREPARATION
Clean all surfaces. Joint walls must be sound, clean, dry,
frost-free, and free of oil and grease and any other con-
taminants. 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. Consult
Sikaflex® Primer Product Data Sheet or Technical Service
for additional information on priming.
APPLICATION METHOD / TOOLS
Recommended application temperatures: 40 to 100 °F (4
to 38 °C). For cold weather application, condition units at
approximately 70 °F (21 °C); remove prior to using. For
best performance, Sikaflex® + Construction 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 entrap-
ment. Avoid overlapping of sealant to eliminate entrap-
ment of air. Tool as required. Joint dimension should al-
low for 1/4 in. (6.3 mm) minimum and 1/2 in. (12.7 mm)
maximum thickness for sealant. Proper design is 2:1
width to depth ratio. For use in horizontal joints in traffic
areas, the absolute minimum depth of the sealant is 1/2
in. (12.7 mm) and closed cell backer rod is recommen-
ded. Tool sealant to ensure full contact with joint walls
and remove air entrapment. Tool as necessary, dry or
with clean water.
For green/new concrete application, 24 hours after con-
crete has cured. Concrete must be of good quality and
strength. Note: Curing will vary depending on temperat-
ure and humidity.
In formed joints, forms must be removed 6 hours be-
fore applying sealant.
▪
In control joints, concrete must be cut 8 hours before
applying sealant.
▪
For wet concrete application, water source must be
stopped 1 hour before application and concrete must be
free of standing water.
CLEANING OF TOOLS
Uncured material can be removed with approved
solvent. Cured material can only be removed mechanic-
ally. For spillage, collect, absorb, and dispose of in ac-
cordance with current, applicable local, state, and feder-
al regulations.
