Weber Foam Fix

Weber Foam Fix is a polyurethane-based, one-component mounting foam that cures through reaction with ambient moisture. In addition to fixing thermal insulation boards, it is also used for installing decorative building elements such as moldings. Its easy application, strong adhesion performance, and high gap-filling capacity make it a practical solution for a wide range of construction applications. It also contributes to thermal and acoustic insulation.

Product Description

Weber Foam Fix is a polyurethane-based, single-component mounting foam that hardens through contact with moisture in the air. It is used as an adhesive for thermal insulation boards and decorative building elements.

Advantages

• Provides strong adhesion
• Fast-curing formula
• High gap-filling capacity
• Contributes to thermal and sound insulation

Areas of Application

Weber Foam Fix is suitable for:

• Bonding XPS and EPS thermal insulation boards
• Installation of decorative moldings and similar architectural elements
• Filling gaps in wall and roof systems
• Sealing wall-to-beam connection points
• Filling expansion joints

Note: The product is not UV resistant. After application, it should be protected with paint, plaster, or another suitable covering.

Suitable Substrates

Can be safely applied to:

• Concrete, precast concrete, fiber-reinforced concrete, cement boards, and roof tiles
• Wood, brick, stone, cement, and plaster surfaces
• Drywall, hardboard, and similar materials
• Metal surfaces

Technical consultation is recommended for applications on other substrates.

Surface Preparation

• The application surface must be clean and dry.
• Oil, paint, dust, and other contaminants must be completely removed.
• Weak coatings should be scraped off and the surface leveled.
• The substrate should be slightly moistened to ensure proper curing.
• Masking may be applied in sensitive areas if necessary.

Application Conditions

• Application temperature: +5°C to +35°C
• Avoid application in extremely hot or highly humid conditions.
• Do not apply to frozen surfaces or surfaces at risk of freezing.

Application Instructions

• Shake the can thoroughly for at least 30 seconds before use.
• Adjust the foam output using the application gun.
• Maintain a distance of 1–2 cm between the nozzle and the substrate during application.
• When installing insulation boards, keep them fixed in place for 8–10 minutes.
• Fresh foam can be cleaned with acetone.
• Cured foam can only be removed mechanically.

Warnings and Recommendations

• Does not adhere to polyethylene, silicone, or Teflon surfaces.
• Avoid impact or movement of insulation boards during installation.
• In low-humidity conditions, lightly moisten the substrate to accelerate curing.
• At low temperatures, allow the product to reach room temperature before use.
• Apply in well-ventilated areas.

Technical Specifications

Storage

• Store between +5°C and +25°C.
• Protect from direct sunlight.
• As a pressurized container, it must be kept away from temperatures above 50°C.

Safety Precautions

• Wear protective gloves, safety goggles, and a mask.
• Avoid contact with skin and eyes.
• In case of contact, rinse thoroughly with plenty of water and seek professional advice if necessary.
