Installation Guidelines
- Keep a gap of a minimum of 10mm and a maximum of 20mm between the wall and frame.
- Substrates should be clean and free of dust and grease but can be moist.
- Loose parts must be removed and if necessary primer must be used (e.g. old plaster)
- Slightly humidify the surface & door frame before applying the foam
- Use protective gloves
- Shake can thoroughly for 30 seconds
Why moistening so important?
- Better cell structure – Acoustic– Thermal
- Faster curing
Applying PU foam
- Hold the can upside down and extrude the foam by pressing the bar
- Spray some extra water if you are filling a gap with some depth or if you are applying the foam in different layers.
- PU foam is a moisture-curing product, it
will cure by absorbing moisture from the
air. Spraying some water on the wall and frame will fasten up the curing process
and will give a better cell structure
(acoustic & thermal properties)
After applying PU Foam
- Spray some additional water on the applied PU foam on both sides of the frame
- After use, clean the valve and tube immediately Foam Cleaner
- Cut the spoiled foam away after curing of PU foam (24 hours)
- Let the foam cure for a minimum of 24 hours
