• The substrate must be clean, sound and homogeneous, free from oils, grease, dust and loose or friable particles. Paint, cement laitance and other poorly adhering contaminants must be removed.
• Sika Boom®-193 adheres without primers or activators to most building materials such as wood, concrete, brick, metal or aluminum.
• Pre-dampen the substrate with clean water, this ensures that the foam cures properly and also prevents secondary foam expansion. 
• For non-conventional substrates, a preliminary adhesion test is recommended.

• Shake Sika Boom®-193 can well for minimum 20 seconds before use. Repeat shaking after long interruptions of use.
• Remove the cap from the canister. Screw the nozzle firmly onto the thread of the valve without pressing the trigger or the valve.
• To ensure proper flow, hold the canister upside down while dispensing. The amount of expanding foam extruded can be regulated by applying more or less pressure on the trigger.
• Fill deep joints in several layers. Allow each layer to expand and harden sufficiently before pre-dampening with water again for next layer application. Fill deep joints in several layers. 

Clean all tools and application equipment with Sika Boom® Cleaner or Sika® Remover-208 immediately after use. Hardened material can only be mechanically removed.
