Product Information
Full details
The Demsun Professional Foam is an essential tool for contractors, DIY enthusiasts, and maintenance professionals looking for a reliable solution to seal gaps, insulate frames, and fill joints. Its standout benefit is a high-yield formula that provides up to 45 litres of material, offering excellent coverage and efficient, precise application. While it offers professional-grade insulation and adhesion, users should note that the foam requires a steady hand during application to manage the 1.5x expansion rate and ensure clean, aesthetic results.

FAQs
Can this foam be used outdoors?
Yes, it is waterproof and mould-resistant, making it suitable for both interior and exterior applications.
Is it safe to use for fire-sensitive areas?
It is rated Fire Class B3 per DIN 4102-1, meaning it meets standard safety requirements for construction foam.
Can I paint over the foam after it dries?
Yes, once the foam has fully cured, you can trim the excess and apply paint to the surface.
How much foam does one canister yield?
One 750ml canister can yield up to 45 litres of cured material, depending on application conditions.
What should I do if foam gets on my hands?
While the foam is wet, it can be cleaned with a specialized foam cleaner or acetone. Once cured, it must be removed mechanically.
Does the foam expand after application?
Yes, it expands up to 1.5 times its dispensed volume, so avoid overfilling gaps.
Troubleshooting
Foam is not dispensing properly
Ensure the valve is fully engaged and the nozzle is not blocked by dried foam. Shake the canister again.
Foam is messy and over-expanding
Apply less material initially; the foam will continue to expand by 1.5 times after leaving the nozzle.
Foam does not adhere to the surface
Ensure the surface is free of grease, dust, and loose debris. Lightly misting the surface with water often improves adhesion for polyurethane foams.

Setup, Compatibility & Care
To use the canister, ensure the surface is clean, free of dust, and slightly dampened to improve the curing process of the polyurethane. Shake the canister vigorously for at least 30 seconds before use. Attach the included applicator straw or a professional gun dispenser. After application, allow the foam to cure; it is typically tack-free within 15 minutes, but should be left for several hours before trimming.
Store the canisters upright in a cool, dry place to ensure the valve mechanism remains functional. Do not expose the canisters to temperatures exceeding 50 degrees Celsius or direct sunlight.
