Method Of Application
NEOFLEX PU 25 LM sealant shall be applied as per the
following general method of application:
Before application, the joint surfaces should be thoroughly
clean, dry and free of all contamination. Apply sealant
evenly, use masking tape and remove the tape while the
sealant is still tacky.
Joint width/depth ratio should be 2:1
Use a high-density polyethylene backer rod as a backup
material always to adjust the joint width – depth ratio.
Sealants should adhere to only two surfaces of the joint to
take care of thermal expansion and contraction of the joint.
