Application and Key Benefits of Arbokol AG2 - Gun Grade
MAIN APPLICATIONS
Recommended for sealing structural floor joints, parapet wall joints, concrete roadways and pavements, hard standing floor pads, joints in concrete sea walls and joints in water retaining (non-drinking water) structures. This 2 part polysulphide sealant is particularly suited to areas requiring long-term flexibility and chemical resistance.
Please contact ARBO Technical Services Department for advice regarding suitability for specific purposes.
Not recommended for use with potable water.
APPLICATION INSTRUCTIONS
Joint preparation
The joint surfaces must be clean, dry, and free from all contamination. The surfaces should be degreased using the appropriate ARBO Cleaner.
ARBO AG2 Porous Primer is recommended on concrete. Contact ARBO Technical Services for specific primer advice.
Mixing
The base and curing agent ratio controls the adhesion, strength, and durability of Arbokol AG2. The components must therefore be thoroughly mixed. This 2 part polysulphide sealant formulation ensures consistent curing and long-term performance in demanding environments.
Application
The normal method of application is to fill the mixed sealant into Arbo Hand Barrel Guns using a heavy-duty follower plate.
The sealant should be extruded firmly into the joint by maintaining an even pressure on the trigger of the gun.
All joint preparation, priming, and sealant application should be carried out in accordance with BS 8000 -16: 1997+ A1: 2010, the British Standard for the sealing of joints in buildings using sealants.
Joint Backing
Where applicable, use appropriately sized closed cell, cross-linked Polyethylene foam.
Cures to form a flexible rubber seal with good adhesion to many substrates
Suitable for use in horizontal and vertical joints
Suitable for sealing joints in concrete-to-concrete applications
