Note : The product’s design and performance, its intended use, installation and final confirmation and approval for use, must be provided by the project’s Design Engineer and Project Manager.

The width of the joint should be a minimum of 4 times the anticipated movement. Joints with cyclic
movement should have a width to depth ratio of 2:1. Minimum depth of the sealant should be maintained as recommended below:

• 10mm for all porous surfaces.
• 20mm for joints exposed to traffic & hydrostatic pressure.
• 5mm for impervious surfaces such as metal, glass, etc.

 JOINT PREPARATION  – The joint surface must be clean, dry and free from oils, loose mortar, laitance, release agents and other contaminants. A thorough wire brushing, grinding, sand blasting or solvent cleaning may be required to expose a clean and sound surface.

PRIMING – Primer should be applied to a clean, dry surface prior to installation of backer rod and/or bond breaker tape. Polyseal Primer is recommended for most common substrates like concrete, tiles, etc. For non-porous substrates like glass & steel, special primer can be applied to achieve optimum adhesion. Where a particularly neat finish is required, apply masking tape on both sides of the joint before priming and remove immediately once the sealant application is complete

BACKING MATERIAL – Closed cell polyethylene backer rod should be used to control the depth of the joint sealant to the recommended thickness. Where joint design or depth of joint will not permit the use of backing rod, use a bond breaker tape.

• 2.5 litre Gun Grade
• Part A & B in the same pail 

• 4.0 litre Pouring Grade
• Part A = 4.0 litre pail
• Part B = 500 ml pail

GUN GRADE
Supplied in a ready to mix container, with all the components packed in a single tin. The material shall be mixed thoroughly with a slow speed drill (300-400 rpm) fitted with a flat bladed paddle for 2-3 minutes till a uniform colour and consistency is achieved.

Note : Mix one full kit at a time to avoid improper mix ratio. DO NOT PART MIX.

POURING GRADE
Supplied in a pre-weighed two parts pack which requires on site mixing. Pour the hardener (Part B) into the base (Part A) pail and mix thoroughly with a slow speed drill (300-400 rpm) fitted to a flat bladed paddle for 1-2 minutes till a uniform colour and consistency is achieved. Note : Mix one full kit at a time to avoid improper mix ratio. DO NOT PART MIX.

FINISHING
Once the sealant has been applied, a suitable rounded tool soaked in soapy water can be used to achieve a smooth finish. Any masking tape applied should be removed before the sealant skins over.

CLEANING
Remove all excess sealant with a scraper. Any spillage can be cleaned using a solvent like Xylol. Clean all tools and sealant gun using a similar solvent immediately after the tooling is finished.

Store in a cool, dry place and keep away from all sources of heat and sunlight. In tropical climates, store in air condition rooms. The shelf life is up to 12 months in un-opened condition and if stored as per recommendations. Excessive exposure to sunlight, humidity and UV will result in the deterioration of the quality of the product and reduce its shelf life.

The surface and joint area to be applied with primer should be dry, clean and free of dirt, dust and any foreign matter. Allow primer to become tacky or touch dry before applying joint sealant. If primer has been applied longer than two hours, re-apply another application. Refer to the joint sealant installation instructions for further information or contact CORKJOINT if joint sealant installation training is required.

 As with all construction chemical products caution should be exercised. Contains manganese dioxide. Which is corrosive and may cause burns to skin if handled without proper protection. Protective clothing such as gloves and goggles should be worn. Treat any splashes to the skin or eyes with fresh water immediately. Should any of the products be accidentally swallowed, do not induce vomiting, but call for medical assistance immediately.

In confined spaces or in still air conditions, the use of a ventilation fan or suitable respirator should be used, and the advice and approval of the Site Safety Supervisor is essential.
