Use MapePUR Universal Foam M/G for: Filling gaps, thermal and sound insulation, and sealing construction features.
MapePUR Universal Foam M/G is a high-quality, one-component expanding polyurethane foam formulated for professional use. Available in both manual (M) and gun (G) application, it's perfect for filling, sealing, and insulating gaps in a wide range of construction applications. This foam provides excellent thermal and sound insulation, adheres strongly to common building materials, and cures rapidly to form a stable, closed-cell structure.
Key Features of MapePUR Universal Foam M/G
- One-component polyurethane foam.
- Available in manual (M) and gun (G) application.
- Excellent thermal and sound insulation.
- Rapid hardening and stable structure.
- Adheres to various building materials.
- Resistant to mould, mildew, and temperature variations (-40°C to +90°C).

Frequently asked questions
Can I use MapePUR Universal Foam M/G to seal around window frames?
Yes, this foam is formulated for the thermal and sound insulation of door and window frames. Its rapid curing and adhesion properties make it suitable for these applications.
Does MapePUR Universal Foam M/G provide sound insulation?
Yes, the foam offers a soundproofing capacity of 58 dB (EN 12354-3 or ISO 717-1). This helps reduce acoustic leakage when filling gaps in building materials.
Is MapePUR Universal Foam M/G fire-rated?
The foam is classified as B3 under DIN 4102, which indicates flammability. It is not a fire-rated or non-combustible foam and should not be used where specific fire resistance is required.
What surfaces will MapePUR Universal Foam adhere to?
It adheres well to common building materials such as brickwork, concrete, gypsum, wood, metal, glass, foam polystyrene, PVC, and rigid foam polyurethane. Always ensure surfaces are clean and prepared.
Applications and benefits
| Application | Key benefit | Primary trades |

MapePUR Universal Foam M/G limitations:
- Does not adhere to polyethylene, silicone, or Teflon.
- Must be protected from UV rays after curing.
- Actual expansion depends on temperature and humidity.
- Wear gloves and eye protection.
- Ensure proper ventilation.
Product limitations
- Not for: Applications requiring specific fire resistance. This foam has a Flammability Class of B3 (DIN 4102), meaning it is flammable.
- Not for: Structural load-bearing applications. This is an expanding filler and insulator, not a structural adhesive.
- Not for: Continuous immersion in water or prolonged direct UV exposure without protection.
- Application temperature: Apply only within 5°C to 30°C.
- Can/contents temperature: Optimum performance at 20°C to 25°C.
Safety and handling
Storage and disposal
Store in an upright position between 10°C and 25°C. Keep away from heat and direct sunlight. The shelf life is 18 months from the production date when stored correctly. Dispose of empty cans according to local regulations.
Substrate guide
Proper substrate preparation ensures maximum adhesion and foam performance for MapePUR Universal Foam M/G.
General building materials
This includes brickwork, concrete, gypsum, wood, metal, and glass.
Surface prep: Clean and prepare the substrate. Ensure surfaces are free from dust, grease, and loose particles. Dampen the substrate with water before application to assist curing and adhesion.
Primer: Not required. Dampening the surface with water acts as the pre-treatment.
Plastics and foams
This includes foam polystyrene, PVC, and rigid foam polyurethane.
Surface prep: Clean surfaces thoroughly. Ensure they are free from release agents or contaminants. Dampen with water.
Primer: Not required. Dampening with water is sufficient for these surfaces.
