Foam Gun MEGA 18018 for Expanding Foam — Manual Applicator for PU Foam Cartridges

Manual foam gun MEGA 18018 for Expanding Foam is an applicator designed to dispense polyurethane expanding foam from standard cartridges with controlled, consistent flow. The tool is suitable for sealing, bonding and filling gaps, joints and cavities during construction, installation and renovation work. It is intended to provide precise foam application, reduce material waste and improve work efficiency for both professional and DIY users.

Advantages

The MEGA 18018 foam gun offers a robust manual mechanism that allows precise metering of foam output and easy adjustment of the flow rate. Its nozzle and valve design reduce clogging and support longer service intervals between cleanings. The applicator is compatible with common cartridge sizes and is constructed to withstand repeated use in on-site conditions. Simple disassembly of external parts makes routine maintenance straightforward.

Suitable for

• Sealing gaps around windows and doors
• Filling cavities and voids in walls and roofs
• Bonding insulation panels and mounting frames
• General repair and finishing work in construction and renovation

Key specifications

• Manual trigger operation for controlled dispensing
• Adjustable flow control for precise metering
• Compatible with standard PU foam cartridges
• Durable metal and polymer construction for on-site use
• Nozzle and valve design that reduces clogging

How to use

Attach a standard polyurethane foam cartridge to the MEGA 18018 applicator following the cartridge manufacturer’s instructions and ensure the cartridge is punctured or connected as required. Adjust the flow control to a low setting for initial tests, then gradually increase to the desired output while maintaining steady movement along the joint or cavity. Hold the gun at a consistent angle and distance to achieve an even bead; fill in layers if necessary to avoid excessive expansion. After use, follow the manufacturer’s cleaning recommendations to remove uncured foam from the nozzle and valve to maintain performance.

Usage recommendations

Use appropriate personal protective equipment, including gloves and eye protection. Store the applicator and remaining cartridges in accordance with foam cartridge storage guidelines, avoiding extreme temperatures. For prolonged pauses, clean the nozzle and valve to prevent cured foam buildup and ensure reliable operation during subsequent use.
