Uses

• Concrete pavement road and industrial floors
• Airport runways
• Joints in crude sewage, sewage sludge and digestion tanks
• Marine structures

Advantages

• High abrasion resistance
• Resistant to Bio – Degradation
• Recommended for immersion joints
• Permanent seal of concrete joints and high resistance to weathering, Ozone and UV- rags

Method of use

Surface preparation

• Concrete surfaces: must be clean and dry. Wire brush thoroughly and remove dust and contaminants.
• Metal surfaces: remove any corrosion or mill scale by grit or shot blast. Degrease the surfaces with cloth soaked in oil free cleaning solvent.
• Wood substrate: must be clean and dry, cut back or abrade where necessary to sound timber.

Priming

A single coat of primer should be applied by brush. The primer must be allowed to dry for a minimum period of one hour before applying HR-2 should be applied within 24 hours of priming.

Mixing

• Pour entire content of part B into part A pail and mix for 3 to 5 minutes, using a paddle fitted to a 500 r.p.m electric drill.
• Do not subdivide the components
• Failure to completely disperse curing agent throughout the base compound will result in uncured sealant.

Application

• HR-2 should be used immediately once mixed.
• Gun with nozzles can be used for easy application
• Tool the sealant with light pressure to spread the material against the joint surfaces, this operation should be made with spatula soaked in a soapy water.
• For good performance, it is essential that the sealant is only bonded to the two facing sides of the joint, to achieve this, install a back up material (closed cell polyethylene or open cell polyurethane foam )
• Application temperature is between 4 to 40°c.

Cleaning

Clean uncured materials with solvent and cured materials mechanically

 Joint Dimensions

• Joints width with minimum 5 mm to max 50 mm
• Joints with cyclic movements should have width: depth ratio of 2:1

• Metals and glass is 5 mm, all porous surfaces are 10mm, joints exposed to traffic and hydrostatic pressures are 20mm.

• 5 mm below flush for joints exposed to traffic
