Expanding Foam (Gun Grade) - 750ml

Product Description:

• High expansion polyurethane foam for filling a variety of voids from door frames to ducts. Uses include insulation, stopping draughts, filling gaps and assisting with dampening sound.
• The foam expands up to 30 times its original volume for an extra tight seal.
• To help with expansion, it is advised to use a spray mister of water to moisten the area to be filled prior to application - this helps the area to cure faster.
• Once the application of the foam is completed and fully cured, the additional unwanted foam can be sanded, scraped or trimmed off depending on preference.

How Does It Work?

• The foam is shot directly into the void with an Expanding Foam Gun (sold separately). 
• Upon contact with the fill area, the foam rapidly expands until the entirety of the void is filled.
• There will likely be protrusion out of the crevice from the foam but this can then be removed using the methods listed above.
• Should there be any excess foam on the applied area, it can be efficiently removed with Expanding Foam Cleaner
