Joint configuration

Minimum Joint width: 6 mm
Maximum Joint width: 50 mm

 
Width: Depth Ratio

The joint width must be designed to suit the movement capability of the sealant. Joints expected to movement a width to depth ratio of approximately 2 : 1 must be maintained. For butt joint the width to depth ratio should be 1 : 1.

  
Minimum joint depth is recommended:

• 6mm for non-porous surfaces
• 8mm for porous surfaces
• 20mm for trafficked joints and joints that are exposed to hydrostatic pressure

At chamfered elements it shall not fill the chamfer with sealant.

Part A : Part B = 94 : 6 (by weight)

+5 °C min. / +50 °C max.

+5 °C min. / +50 °C max.

Dry joint with sound concrete edges. For joints under wet conditions, use Sika®-Primer-PS.

~2 h at 25 °C

1 week

All surfaces must be clean, dry and free from any loosely adhering particles.

Check the joints edges for soundness and if found weak cut recess and fill up with suitable repair mortar (Consult Sika Technical Department). Correct joint depth can be established by inserting closed cell polyethylene backing rod tightly into the joint. When the joints have been filled with fiber filled board, this must be raked back to the required depth. Use bond breaker tape over the backer material. Protect surfaces with masking tape.

PRIMING

Sika® Polysulphide PG should be used as a primer only on two sides of the joint. The flash off time is minimum 30 minutes and maximum 3 hours.

Add Component B into the bigger Component A pail. Mix the product thoroughly with a mixing paddle fitted to an electric hand drill not exceeding 500 rpm to avoid entrapping air. Mix for approximately 5 minutes until a smooth, even consistency is achieved.

Clean all tools and application equipment with Sika® Colma Cleaner immediately after use. Hardened / cured material can only be mechanically removed.
