What is PU Foam Spray?
Polyurethane (PU) foam spray is a two-component insulation material made by combining:
- Component A: Polyol blend
- Component B: Isocyanate
When mixed and sprayed, the two react to form a rigid, closed-cell foam that expands up to 30 times its liquid volume — filling cracks, cavities, and surfaces to create a seamless, airtight, and waterproof insulation layer.
This makes PU foam spray one of the most efficient modern insulation materials in the world.

Application Process of P U foam Spray in Kenya
- Surface Preparation: Clean and dry surface (no dust, oil, or rust).
- Mixing: Components A (polyol) and B (isocyanate) are pumped into a spray gun at controlled pressure and temperature.
- Spraying: Foam expands immediately on contact, forming a continuous insulation layer.
- Curing: Cures within 5–10 minutes; fully set in 24 hours.
- Finishing: Can be coated or painted for UV and weather protection.
Safety & Storage Guidelines
- Store at 20–25°C, away from sunlight and moisture.
- Use protective gear (gloves, goggles, mask) during application.
- Maintain proper ventilation when spraying indoors.
- Keep containers sealed tightly when not in use.
- Shelf Life: 6 months (unopened).

Frequently Asked Questions (FAQs)
Q1: What is PU Foam Spray used for?
A: PU foam spray is used for thermal insulation, waterproofing, and soundproofing in buildings, cold rooms, and industrial equipment.
Q2: Is PU Foam Spray safe?
A: Yes, when applied properly. Once cured, PU foam is non-toxic, odor-free, and inert.
Q3: Can I apply it myself?
A: For small repairs, yes. For large-scale insulation, professional spraying equipment and expertise are recommended.
Q4: How long does PU foam last?
A: Properly installed PU foam lasts 20+ years without losing insulation performance.
Q5: Can it be painted or plastered over?
A: Yes. PU foam can be coated with UV-resistant paints or cementitious coatings for long-term protection.
