JOINT DESIGN

1. For cyclic movement joints should be designed so as to give an optimum
   width to depth ratio of 2:1.
2. For porous substrates minimum sealant depth should be 10 mm.
3. For nonporous substrates minimum depth should be 6 mm.
4. For horizontal joints minimum depth should be 12.5 mm.
5. For joints subjected to traffic or hydraulic pressure minimum depth should be 20 mm.

INSTRUCTIONS FOR USE

A. Preparation of substrate

1. Clean the surface free of all dirt, dust, and cement laitance and any deleterious matter with a wire brush followed by blowing clean air.
2. Metallic surfaces must be free of rust, scale or protective lacquers.

B. Priming

1. Two primers are available
   SUNJOINTSEAL PRIMER A and SUNJOINTSEAL PRIMER B
2. Use SUNJOINTSEAL PRIMER A on porous surfaces such as concrete, brick, stone etc. and SUNJOINTSEAL PRIMER B on non porous surfaces such as steel, glazed ceramics, glass etc.
3. Before the application of the sealant, the joint surface should be primed.
