FAQ
For best results, the cured foam may be painted or coated for outdoor applications
Cured foam will discolour if exposed to ultraviolet light.
The average house can lose up to 30 % of its heat because of drafts. So by weather sealing and insulating around your windows, you can help control indoor temperature and stop losing energy efficiency, which means lower energy bills.
The Sika Boom®AS includes a convenient reusable dispensing straw. So to ensure that the straw can be reused: 1) set the can upright and 2) while it is still full of foam, fold back the straw over itself and slide the open end onto the plastic tip located above the trigger to a depth of 10 mm. This will keep the straw air-free. When you are ready to re-use the product, simply shake the can, unfold the straw and proceed with spraying.
Shake Sika Boom® AS can well for about 60 seconds before use. Repeat shaking after long interruptions of use. Turn the Sika Boom® AS can upside down and screw the straw adapter firmly into place without pressing the valve. Regulate the foam flow by applying more or less pressure on the valve/adapter. Sika Boom® AS can only be used in the upside position, failure to invert the can will prevent the foam from dispensing properly. Fill deep cavities 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. Fill the cavity approximately 30 % to allow for expansion. All building elements must be temporarily fixed until the foam has fully cured.
Sika Boom is an all-season product. The service temperature is between - 40 °C to 80 °C and the application temperature is between - 12 °C to 30 °C.
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. Pre-dampen the substrate with clean water, this ensures that the foam cures properly and prevent secondary foam expansion.
