Application Instructions

• For the application of Sika Boom® S all generally accepted rules of building and construction applications.

Substrate Preparation

• 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® S adheres without primers and/or activators.
• Pre-dampen the substrate with clean water, this ensures that the foam cures properly and also prevents secondary foam expansion.

Application Method/Tools

• Shake the Sika Boom® S can well for a minimum of 20 seconds before use. Repeat shaking after long interruptions of use. Screw the nozzle firmly into place without pressing the trigger or the valve. The amount of expanding foam extruded can be regulated by applying more or less pressure on the trigger. Fill deep joints in several layers. Take care to allow each layer to cure and expand sufficiently by spraying water between each layer or allowing sufficient waiting time between the layers. Do not fill hollow sections completely as the foam expands during curing. All building elements must be temporarily fixed until the foam has fully cured.

Cleaning of Tools

• Clean all tools and application equipment immediately with Sika Boom®-Cleaner and/or Sika® Remover-208. Once cured, residual material can only be removed mechanically.

Limitations

• The minimum can temperature for application must be +10 °C.
• In order to get a good quality foam, the can temperature should not vary more than 10 °C from the ambient temperature.
• Protect the can from direct sunlight and temperatures above +50 °C (danger of explosion).
• For correct curing of the foam, moisture is necessary.
• Applying insufficient moisture may lead to subsequent unintended foam expansion (post-expansion).
• Do not fill hollow sections completely as the foam expands during curing.
• Do not use on polyethene (PE), polypropylene (PP), polytetrafluoroethylene (PTFE / Teflon), silicone, oil, grease and other separating agents.
• Sika Boom® S is not resistant to UV light.
• Read all safety and technical recommendations which are printed on the Sika Boom® S can.
