Polyurethane Foam Sealant Fire Rated dense cell structure self-extinguishable PU foam

Method of use:

If the gun type PU FOAM is used, when using, turn the tank upside down and connect with the spray gun thread, turn to open the flow valve, and adjust the flow before spraying.  

If the tubular PU FOAM is used, screw the plastic | exam large | nozzle on the valve thread, align the plastic tube with the gap, and press the nozzle to spray.

Before use, shake the PU FOAM agent tank for at least 60 seconds to ensure that the material in the tank is uniform.

Before construction, oil stains and floating dust on the construction surface should be removed, and a small amount of water should be sprayed on the construction surface.

Pay attention to the travel speed when spraying, usually the spray volume is half of the required filling volume. Filling vertical gaps should be from bottom to top; when filling gaps such as ceilings, uncured foam may fall due to the action of gravity. It is recommended to provide proper support just after filling, and after the foam is cured and bonded to the wall of the gap Then withdraw the support. The foam will be debonded in about 10 minutes, and it can be cut after 60 minutes. Cut off the excess foam with a knife, and then coat the surface with cement mortar, paint or silica gel.
