## Summary description

Manual foam applicator pistol K2 B520 (K2 FOLT) designed for dispensing polyurethane assembly foam. Hand-held tool for controlled application of construction and insulation foam from cans, providing directional delivery and reduced waste. Suitable for sealing, filling gaps, mounting window and door frames, and general insulating and bonding tasks in construction and renovation.

## Long description

The K2 Foam Gun B520 (K2 FOLT) is a manual assembly foam applicator pistol designed for controlled dispensing of polyurethane construction and insulation foam from standard cans. This hand-held applicator provides directional delivery with a precision valve and ergonomic trigger for reduced waste and improved accuracy when sealing, filling, mounting window and door frames, or bonding insulating materials. The construction materials and nozzle design allow for repeated use and easier cleaning compared with simple straw dispensers.
Advantages
The K2 Foam Gun B520 offers precise flow control through an adjustable valve that lets the user regulate bead size and foam output. Its ergonomic handle and balanced weight make prolonged use less tiring, while the metal body and threaded connection ensure a secure fit to most standard foam cans. The applicator minimizes overspray and dripping, leading to cleaner results and reduced material waste during insulation and mounting tasks.
Suitable for
 Sealing gaps and joints in walls and around plumbing penetrations
 Mounting and fixing window and door frames
 Filling voids, cavities, and thermal insulation gaps
 Adhesive bonding for lightweight construction panels and materials
 General renovation and construction sealing tasks
Key specifications
 Type: manual foam applicator pistol for polyurethane aerosol cans
 Control: adjustable flow valve for precise bead regulation
 Body material: durable metal construction for stability and longevity
 Connection: standard threaded can interface compatible with common aerosol foam cans
 Trigger: ergonomic trigger design for controlled single-handed operation
 Nozzle: directional delivery spout for accurate application and reduced waste
How to use
Attach the K2 Foam Gun B520 to a compatible polyurethane foam can by screwing the can into the gun's threaded connection while the valve is closed. Shake the foam can according to the can manufacturer's instructions before use. Open the adjustable valve slightly and depress the trigger to apply foam; adjust the valve to increase or decrease the foam flow as needed. Apply beads steadily to the joint or gap, maintaining a consistent distance and speed for uniform coverage. After use, wipe excess foam from the nozzle and follow recommended cleaning procedures to prevent curing inside the gun.
Usage recommendations
Use protective gloves and eye protection when dispensing polyurethane foam. Work in a ventilated area and follow the foam can manufacturer's safety and storage guidelines. To prevent blockages, clean the applicator after each use or attach a compatible gun-cleaning cartridge; store the gun with the valve closed and a thin protective layer of recommended solvent if longer storage is anticipated.
