Expanding Foam Multipurpose Polyurethane Filler 500ml 🧰

This expanding polyurethane foam offers a practical solution for sealing gaps around doors, windows, frames and pipe penetrations, combining firm adhesion with thermal and acoustic insulation for domestic and light construction use. Quick to apply, the 500 ml aerosol expands to fill cavities and sets with ambient moisture, making it useful for both indoor and outdoor repairs.

Key Points

This product adheres reliably to common building materials including concrete, wood, metal and many plastics, which helps stabilise joints and stop drafts. According to the manufacturer, the formulation resists a wide range of environmental conditions, such as exposure to sea water, diluted acids and alkalis, steam and sustained humidity. The foam also contributes to heat retention and sound reduction, helping to lower heat loss and reduce noise transmission where applied. It comes as an aerosol can that requires shaking and attaching the supplied nozzle before dispensing, and it cures rapidly when it meets moisture in the air.

Technical Specifications

• Name: professional soma fix Expanding Foam - Multipurpose Polyurethane Foam Filler
• Capacity: 500 ml
• Application areas: doors, windows, frames, pipes, cracks and holes.
• Weather resistance: all-weather performance claimed by the manufacturer.
• Material compatibility: concrete, wood, metal and many plastics.

Benefits

The foam provides a combination of mechanical bonding and insulating properties, which means fewer separate products are needed for sealing and insulation tasks. Its all-weather tolerance supports outdoor use even in areas subject to salt spray or damp conditions, and the quick expansion reduces the time spent on filling irregular cavities. For jobs where noise reduction matters, the material helps mitigate airborne sound transfer across small gaps. Consider that curing time and final rigidity depend on ambient temperature and humidity, according to the manufacturer.

Usage Recommendations

Before application, shake the can well and attach the nozzle securely, then dispense into the deepest part of the cavity and allow the product to expand naturally. Avoid overfilling because the foam continues to expand after application, and cut back any excess once fully cured if a flush finish is required. For working on vertical joints or overhead spaces, support the area as necessary and use appropriate personal protective equipment such as gloves and eye protection. 🛠️ For best adhesion on non-porous surfaces, slight abrasion of the substrate may improve mechanical grip. 🔧.
