## Long description

The Topex caulking gun 21B235 is a manual tool designed for dispensing silicone and other cartridge-based sealants with controlled flow. Compatible with standard cartridges, it offers a straightforward mechanism for applying bead sealant during sealing, bonding and finishing work in construction and renovation projects. The ergonomic handle and sturdy frame make it suitable for both occasional DIY tasks and regular professional use in glazing, bathrooms and kitchens.

Key specifications
 Type: manual caulking gun for cartridge sealants
 Compatibility: standard cartridge sizes commonly used for silicone and sealants
 Operation: trigger-driven dispensing for controlled bead application
 Handle: ergonomic design to reduce hand strain
 Frame: metal construction for stable support during application
How to use
Prepare the surface by cleaning and drying the area where the sealant will be applied. Cut the cartridge nozzle to the required bead size and pierce the inner seal if present. Insert the cartridge into the gun, ensuring it is seated securely, then engage the trigger to advance the plunger and begin dispensing. Move the gun steadily along the joint to produce an even bead, and smooth the sealant with a suitable tool or finger before it skins over. After use, release the pressure according to the gun mechanism to prevent further flow.
Usage recommendations
Use compatible silicone or acrylic cartridges and select the correct nozzle size for the joint width. For long runs, maintain a consistent trigger rhythm and keep the gun angled to match the joint profile. Store the tool in a dry place and clean any sealant residues promptly to preserve the mechanism.
