Application steps

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®-AP adheres without primers and/or activators. Pre-dampen the substrate with a mist spray of clean water to ensure the foam cures properly and prevent secondary foam expansion.

APPLICATION

Shake the Sika Boom® AP can well for a minimum 20 seconds before use, repeat shaking after long interruptions of use. Screw application trigger straw nozzle onto the valve of the can. 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 cure and expand sufficiently by mist spraying clean water between each layer and allowing sufficient waiting time between layers. Do not fill hollow sections completely as the foam expands during cure. Where small gaps have to be filled use an extension tube. All building elements must be temporarily fixed until the foam has fully cured. Fully cured foam can be cut to shape and painted.

CLEANING OF EQUIPMENT

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