All-Season General Purpose PU Foam — One-Component Polyurethane Foam Sealant (300ml)
All-Season General Purpose PU Foam is a high-performance one-component, moisture-curing polyurethane foam formulated for reliable use throughout the year. Its all-season formula maintains stable expansion and curing performance even in cold weather conditions, making it the ideal choice for professional contractors and DIY users who need dependable gap filling, sealing and insulation in every season.
The foam dispenses smoothly and expands uniformly to fill irregular cavities around door and window frames, pipe penetrations, wall joints and roof structures. Once cured, it forms a rigid, durable barrier that provides excellent thermal insulation, sound damping and waterproof sealing, effectively blocking air leakage, moisture ingress and energy loss.
With low shrinkage and strong adhesion to most building substrates, this general-purpose foam delivers long-lasting performance for a wide range of construction, renovation and installation projects.

Key Performance Features
- All-season formula — stable expansion and curing performance even in cold weather
- High expansion ratio — fills irregular gaps and cavities completely and evenly
- Excellent waterproof sealing — blocks moisture, draughts and air leakage
- Superior thermal insulation — low thermal conductivity reduces energy loss
- Effective sound damping — reduces airborne noise transmission through joints
- Low shrinkage — dimensionally stable after full cure, no cracking or gap reopening
- Strong adhesion — bonds firmly to concrete, brick, wood, metal, PVC and most rigid plastics
- Easy to use — dispenses smoothly and can be cut, sanded and painted once cured
Typical Applications
- Door and window frame installation, sealing and insulation
- Pipe, cable and duct penetration sealing in walls and floors
- Gap filling around wall joints, roof structures and partition boards
- Sealing of electrical outlets, air-conditioning sleeves and HVAC components
- Insulation and sealing in renovation, decoration and new construction
- General gap filling and bonding where reliable all-weather sealing is required
Application Instructions
1. Shake the can vigorously for at least 30 seconds before use.
2. Clean the substrate surface — remove dust, oil, grease and loose particles.
3. Moisten the application area lightly with water for optimal curing (recommended in cold or dry weather).
4. Hold the can upside down and dispense foam into the gap, filling approximately 50% of the cavity to allow for expansion.
5. Allow the foam to cure fully (minimum 24 hours) before cutting or applying load.
6. Trim excess foam with a sharp knife or saw. Cured foam can be sanded and painted.
Safety & Storage
