PACKING

Area Of Application:

• Concrete highways
• Garages
• Airport runways
• Bridges
• Aircraft fueling areas
• Subways
• Parking and cargo areas
• High rise buildings

Method of Application

• Prepare the joints as per recommended width/depth ratio. Prime only on two sides of the properly prepared joint surface with Dr. Fixit Pidiprime A by brush.
• Use closed cell polyethylene foam board and rod as a back up material. Fix masking tape over the backup material leaving exact depth of sealant fill and on both side of joint

Mixing :

• The curing agent is to be poured in the tin with the base and mixed thoroughly with a slow speed electric mixer (300 to 450 rpm) for approx. 5-6 min. until a homogeneous, uniformly grey coloured material is obtained.
• Fill cartridge and fix in the gun for application. Fill the joint either with gun or spatula or pour directly into the joint. Tool the sealant immediately with tooling knife to ensure 100% contact and adhesion with the surface. This will also remove any entrapped air.
• After sealing the joint the tools and equipment should be cleaned immediately with kerosene or any other cleaning solvents
• Remove masking tape by pulling it outwardly.
• Allow sealant to cure for 7 days.

Precautions & Limitations

• Maximum width for application in a joint is 50 mm
• Do not expose the sealant to high temperatures
• Sealant will not adhere to substrates with contamination and traces of bitumen
• Adhesion of the sealant must only be on two opposite faces
• Do not carry out sealing operations during hot temperature conditions
• Use of shalitex board as a back up material should be avoided
