Sika Boom® AP

1-part Polyurethane, moisture curing

Sika Boom®-AP has a shelf life of 12 months from the date of production, if stored properly in undamaged, original, sealed packaging, and if the storage conditions are met. Opened cans of Sika Boom®-AP must be used within a short period after opening.

Sika Boom®-AP shall be stored in an upright position, in dry conditions, protected from direct sunlight and at room temperature.

~24 kg/m³

−40 °C min. / +90 °C max.

Sika Boom® AP is fully cured after 24h (Depending on the foam thickness, ambient and substrate temperature).

~40-60 minutes (Depending on the foam thickness, ambient and substrate temperature).

~10 minutes (depending on ambient humidity and temperature levels).

Consumption can be regulated by adjusting the pressure on the valve. All values are approximations.

Yield may be reduced in aged material.

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

Shake thoroughly (at least 20 times) prior to application.

Apply the nozzle to the can then apply the foam by holding the can in any direction and pointing the nozzle into the area of application then applying pressure to the nozzle trigger. The amount of foam applied can be regulated by the amount of pressure applied to the nozzle. Ensure applications in deep voids are applied in layers allowing each layer to fully cure before application of the next layer (Applied foam must be allowed access to sufficient moisture in order to fully cure).

Fully cured foam can be cut to shape and painted.

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