Super Tack PU Foam — High Adhesion Polyurethane Foam Sealant (750ml)
Super Tack PU Foam is a premium one-component, moisture-curing polyurethane foam engineered for applications demanding exceptional bonding strength. Its high-tack formula grips aggressively to most building substrates, creating a permanent bond that locks gaps, joints and cavities in place while delivering superior thermal and acoustic insulation.
Unlike standard expanding foams, Super Tack PU Foam features an optimized adhesion system that forms an immediate mechanical bond on contact, reducing slip and displacement during installation. The uniform, high-density cell structure cures to a rigid, dimensionally stable foam with minimal post-cure shrinkage, ensuring long-lasting sealing performance even under thermal cycling and structural movement.
Ideal for professional contractors and DIY users alike, this foam is specially formulated for door and window frame fixing, wall panel bonding, pipe penetration sealing and general construction gap filling where strong adhesion is critical.

Key Performance Features
- Ultra-high initial tack — grabs substrates on contact, no waiting for tack-up
- Strong multi-surface adhesion — bonds to concrete, brick, stone, wood, metal, PVC and most rigid plastics
- High-density cell structure — rigid, load-bearing cured foam with uniform cell distribution
- Low shrinkage — dimensionally stable after full cure, no cracking or gap reopening
- Excellent thermal insulation — low thermal conductivity reduces energy loss through sealed joints
- Superior acoustic damping — reduces airborne and structure-borne noise transmission
- Water-resistant — cured foam resists moisture ingress and prevents water penetration
- Paintable & sandable — can be cut, sanded and painted once fully cured
Typical Applications
- Door and window frame installation and fixing
- Bonding and sealing of wall panels, cladding and insulation boards
- Pipe and cable penetration sealing in walls and floors
- Gap filling around electrical outlets, ductwork and HVAC components
- Structural joint sealing in renovation and new construction
- General construction bonding where high adhesion 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.
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
- Extremely flammable aerosol. Keep away from heat, sparks and open flames.
- Use only in well-ventilated areas. Wear protective gloves and eye protection.
- Do not puncture or incinerate the can, even when empty.
- Store in a cool, dry place below 25°C. Keep out of direct sunlight.
- Keep out of reach of children.
