Construction caulking gun GEKO 850 ml with set of 4 nozzles

Manual construction caulking gun GEKO 850 ml with set of 4 nozzles is a handheld dispensing tool designed for controlled extrusion of sealants, adhesives and repair mortars. The gun accepts 850 ml cartridges or sausages and is intended for use on building sites, renovation works and general maintenance tasks. The included set of four interchangeable nozzles allows variation in bead shape and flow for different materials and joint sizes.

Advantages

The GEKO caulking gun features a manual lever mechanism that provides precise control over material flow and bead size. The 850 ml capacity reduces the need for frequent refills during larger jobs. Interchangeable nozzles expand the gun’s versatility by enabling different bead profiles and improved control with viscous materials. The gun is suitable for both professional and DIY use due to its straightforward mechanical design and durable construction.

Suitable for

• Applying silicone and acrylic sealants in joints and gaps
• Dispensing construction adhesives and contact adhesives
• Applying repair mortars and patching compounds
• Renovation and finishing tasks where controlled extrusion is required

How to use

Load the caulking gun with an 850 ml cartridge or sausage, secure it in the frame, and select an appropriate nozzle from the included set. Cut the nozzle tip to the desired bead size and attach it. Advance the plunger using the manual lever until material reaches the nozzle, then apply an even steady pressure to extrude the sealant or mortar along the joint or surface. Release the pressure or engage the release lever to stop material flow. After use, remove remaining material from the nozzle and clean according to the sealant or adhesive manufacturer’s instructions.

Usage recommendations

For best results, choose a nozzle opening that matches the joint width and material viscosity. Use steady, consistent pressure to maintain an even bead. When working with solvent-based or quick-curing materials, clean the nozzle and gun components promptly to prevent clogging and ensure long service life.
