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

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 PS 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

• PS 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 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
• Sealant depth shall not exceed joint width
• Minimum sealant depth recommend for :

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
