Specifications
| Brand | Everbuild |
|---|---|
| Grade | Gun Grade (professional applicator use) |
| Volume | 750ml canister |
| Setting Type | Quick setting, moisture-cured polyurethane |
| Finish | Trimmable and paintable once cured |
| Application Method | Foam gun (gun adapter fitting) |
| Use | Internal and external |
What it's used for
- Filling and sealing gaps around door frames and window frames during fitting or remedial work
- Insulating and draught-proofing around pipe penetrations through walls and floors
- Filling voids and cavities in blockwork, masonry, and timber-frame construction
- Securing and stabilising frames in openings prior to final fixing and finishing
Fitting and handling
Shake the canister thoroughly before use and attach to a suitable foam gun for controlled dispensing. Apply in short bursts into the gap or void, filling no more than half the space as the foam will expand to roughly double its dispensed volume. Once fully cured, the foam can be trimmed flush with a sharp knife and overpainted with most standard decorating paints. Store the canister upright in a cool, dry location and use promptly once opened to prevent the nozzle and gun from blocking.
FAQ
How long does Everbuild Gun Grade Expanding Foam take to cure?
Surface tack is typically achieved within 15 to 20 minutes. Full cure depends on temperature and humidity but is usually complete within 4 to 8 hours under normal UK indoor conditions. Higher humidity actually speeds up the curing process.
Can I use this foam without a foam gun?
This product is specifically formulated as a gun grade foam, meaning it requires a foam gun applicator for correct dispensing and dose control. Using a compatible foam gun also extends the usable life of the canister between applications by sealing the valve when not in use.
Is Everbuild expanding foam suitable for filling gaps around external door frames?
Yes, once cured the foam is moisture-resistant and suitable for external use, making it appropriate for sealing around external door and window frames. Any exposed foam on external faces should be trimmed back and covered with a suitable exterior filler or sealant to protect it from UV degradation.
For joinery installation projects, Nottage Timber Merchants stocks a full range of door linings and frames alongside adhesives and fixings. We supply trade and retail customers from our Bridgend trade counter in South Wales, with next-day delivery options available across the South Wales area.
