## Summary description

Dell Polynor Home 750 ml spray polyurethane (PU) insulation foam for sealing, filling and bonding in construction and DIY projects.

## Long description

Dell Polynor Home 750 ml spray polyurethane (PU) insulation foam is a ready-to-use aerosol designed for sealing, filling and bonding tasks in construction and DIY. The product expands after application to fill gaps and cavities, cures to a closed-cell foam that delivers thermal and acoustic insulation, and adheres to common building materials. The 750 ml format provides extended application time for window and door installation, pipe and cable penetrations, and general gap filling both indoors and outdoors where polyurethane foam is appropriate.
Advantages
The spray foam combines fast expansion with controlled dispensing for precise application. It forms a durable, moisture-resistant seal that improves thermal performance and reduces noise transmission. Cures quickly at typical ambient conditions, allowing subsequent trimming, finishing, or painting. The aerosol format makes it convenient for single-person use and for accessing narrow or recessed voids. It adheres well to wood, masonry, metal and some plastics when surfaces are clean and dry.
Suitable for
 Sealing gaps and joints around windows and doors
 Filling cavities, cracks and voids in walls and floors
 Insulating and soundproofing around pipes and ducts
 Bonding lightweight construction elements and mounting panels
 General DIY repair and weatherproofing tasks both indoors and outdoors
When it may not be suitable
This polyurethane foam may not be suitable for situations requiring structural load-bearing or for use on surfaces that cannot tolerate solvents. It is not intended for constant immersion in water or long-term direct exposure to strong UV without a protective coating. Use caution on certain plastics and elastomers; compatibility tests are recommended before large-scale application.
Key specifications
 Form: sprayable single-component polyurethane foam
 Volume: 750 ml aerosol can
 Application temperature range: typical ambient application temperatures (check label for exact limits)
 Properties after curing: thermal insulation and acoustic damping, closed-cell structure, moisture resistance
 Adhesion: bonds to wood, masonry, metal and many construction materials when prepared
How to use
Shake the can thoroughly before use and attach the supplied applicator if provided. Apply to clean, dust-free and slightly damp surfaces for optimal adhesion and foam expansion. Dispense foam in layers to avoid excessive overfill; allow each layer to cure partially before applying the next. After curing, excess foam can be trimmed, sanded and finished with sealant or paint as required. Follow the safety and handling instructions printed on the can, including ventilation and protective equipment recommendations.
What to consider before purchase
 Ensure the product volume and yield match the size of the job
 Verify surface compatibility for the materials you will bond or seal
 Check recommended application temperature and curing times for your conditions
 Plan for personal protective equipment and adequate ventilation during use
Usage recommendations
For best results, use Dell Polynor Home PU spray on prepared surfaces at moderate temperatures, apply in layers for controlled expansion, and protect cured foam from prolonged UV exposure with paint or trim. Test on a small area where material compatibility is uncertain.
