FAQ
What sealant types can this caulking gun dispense?
The LD-153 is compatible with standard 300ml cartridge sealants including silicone, polyurethane, acrylic latex, butyl rubber, and general-purpose construction adhesives. For very high-viscosity materials, our heavy-duty 18:1 or 26:1 models are recommended.
How does the 360-degree rotation work?
A rotation mechanism at the barrel-to-handle junction allows the barrel to spin a full 360 degrees independently of the handle. This lets you maintain a comfortable grip angle while directing the nozzle precisely at the work surface, essential for corners and overhead work.
What is the difference between 9-inch and 10-inch models?
The 9-inch model is shorter and more compact for tight spaces and overhead work. The 10-inch model provides longer reach and better leverage for floor-level and wall applications. Both accept standard 300ml cartridges.
How do I clean the caulking gun after use?
Remove the spent cartridge, wipe excess sealant from the barrel and plunger with a cloth or paper towel. For cured sealant residue, use a sealant remover solvent. Apply a light coat of petroleum jelly to the plunger rod before storage to prevent sticking.
