Arbo AG2 Gun Grade is a two part Polysulphide Sealant which cures once the two components are mixed together to give a flexible rubber seal. It has good adhesion to concrete, stone, metals and many other common building substrates.

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.
• 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. 

Mixing

The base and curing agent ratio controls the adhesion, strength, and durability of Arbokol AG2. The components must therefore be thoroughly mixed.

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.
