## Long description

Topex TOP-21B507 is a mounting foam gun designed to provide controlled dispensing of polyurethane assembly foam for sealing, filling and bonding tasks in construction and renovation.

How to use
Attach the foam canister to the threaded connection according to the canister manufacturer's instructions, ensuring a secure fit before use. Hold the gun by the handle and press the trigger gently to start dispensing; use the adjustable valve to regulate the foam output until the desired flow is achieved. Apply foam in short bursts for controlled filling, allowing foam to expand as specified by the foam manufacturer. After application, allow the foam to cure fully before trimming or finishing surfaces. Follow safety guidance for ventilation and protective equipment when working with polyurethane foam.
Usage recommendations
For consistent results, use compatible polyurethane foam canisters and clean the applicator immediately after use according to the manufacturer's cleaning procedure. Store the gun in a dry place and periodically check the valve and nozzle for blockages. When working in cold conditions, keep canisters and the applicator within the recommended temperature range to ensure even dispensing.
