Why Use Fixo 88 PU Foam?
Fixo 88 PU Foam is a single-component, moisture-curing, self-expanding polyurethane foam designed for sealing, filling, insulating, and bonding applications in construction and maintenance. Supplied in a convenient aerosol can with a straw applicator, it expands after application to fill gaps, cracks, cavities, and joints, creating a strong, waterproof, and durable seal. It adheres to most common building materials, making it ideal for professional contractors and DIY users.
The advanced polyurethane formula cures quickly and becomes tack-free in less than 10 minutes. As a result, installation and repair work can continue without long waiting times. Furthermore, the cured foam provides excellent thermal and sound insulation while resisting temperatures from -45°C to +80°C, ensuring reliable performance in demanding indoor and outdoor environments.

Fixo 88 PU Foam Benefits
Fixo 88 PU Foam simplifies sealing and insulation tasks by expanding to fill difficult gaps and cavities. In addition, it improves energy efficiency by reducing air leakage and heat loss. Consequently, buildings become better insulated while noise transmission is reduced. Moreover, the waterproof seal helps protect structures against moisture infiltration and improves the durability of installation work.
Fixo 88 PU Foam Applications
Fixo 88 PU Foam is suitable for door and window frame installation, gap filling, wall penetrations, roof joints, pipe openings, electrical conduit sealing, HVAC installations, insulation projects, construction joints, cavity filling, crack sealing, soundproofing, and general building maintenance. It bonds well to concrete, brick, wood, metal, stone, and masonry, except surfaces such as Teflon, silicone, polyurethane, and oily or greasy materials.
How to Use Fixo 88 PU Foam
First, clean the application surface thoroughly and remove dust, grease, and loose particles. Lightly moisten dry surfaces to improve curing. Next, shake the can vigorously about 20 times before use. Attach the spray nozzle securely, hold the can upside down, and apply the foam evenly into the gap or cavity. Afterwards, allow the foam to expand naturally without overfilling the space. Once cured, trim any excess foam with a knife if necessary. For outdoor use, paint or coat the cured foam to protect it from UV radiation.
Safety Precautions
Always store and transport the can in an upright position. Keep it at room temperature for at least 12 hours before use. Wear protective gloves, safety glasses, and suitable clothing during application. Use only in well-ventilated areas and avoid inhaling vapors. Keep the product away from direct sunlight, open flames, and temperatures above 50°C. Never puncture or burn the container, even after use, and always keep it out of the reach of children.
Fixo 88 PU Foam delivers fast curing, strong adhesion, excellent insulation, and reliable waterproof sealing. Therefore, it is an ideal solution for construction, renovation, insulation, and professional sealing applications.
