Application:

• The optimum temperature for substrate and sealant is between 15 deg c and 25 deg c.
  
• Can be applied by hand gun or air power.
• For optimum performance the joint width needs to be designed according to the movement capability of the sealant based on the actual expected movement.
• The minimum joint depth is 6 mm and a width depth ratio of minimum 2 to 1 and maximum of 4 to 1.
• Joints deeper than 15 mm must be avoided.
• It is recommended to use closed cell foam backer rods.
• If joints are too shallow for backing material to be employed, we recommend using a polyethylene tape,
• This acts as a bond breaker allowing the joint to move and the silicone to stretch freely.
  
• Uncured Sikasil WS-605 S can be removed from tools equipment and surfaces with Sika Adhesive Remover-208.
