FAQ – Frequently Asked Questions

What types of cartridges can I use?

This cordless sealant gun is exclusively suitable for 310 ml rigid cartridges. It does not support 400 ml cartridges or foil packs.

What materials can I dispense with the gun?

You can use the device for a variety of sealants and adhesives:

• Silicone – for joints in wet areas such as bathrooms or kitchens

• Acrylic – suitable for indoor applications such as wall and ceiling gaps

• MS polymers – for elastic bonding with high adhesion

• PU-based sealants – depending on viscosity, suitable for some 1K polyurethane products

Note: Only single-component (1K) cartridges are supported. These contain materials that cure through air moisture. Two-component (2K) systems are not suitable.

What does "1K" mean?

"1K" refers to single-component cartridges. These products harden when exposed to humidity. Unlike 2K systems, they do not require mixing before application.

What is "viscosity"?

Viscosity describes the thickness or flow resistance of a material. High-viscosity materials (e.g. cold silicone or MS polymer) are more difficult to press and require a powerful device. This cordless sealant gun is designed to handle such materials with ease.

How can I adjust the material flow?

You have two ways to control the dispensing speed:

• Rotary dial for coarse speed settings

• Trigger for precise fine control while applying

Can I use the device outdoors?

Yes, the robust housing and powerful battery make it suitable for outdoor use – e.g. for sealing façades, balconies, or terrace joints.

What is the benefit of automatic pressure relief?

As soon as you release the trigger, the material flow stops immediately. This prevents dripping and ensures a clean work area.

How heavy is the device during prolonged use?

Weighing only 1.88 kg including the battery, this gun is very lightweight and ergonomically designed for extended operation.

How long does the battery last?

A full charge takes approx. 60 minutes. The runtime depends on the material used and application speed. We recommend having a second battery ready to avoid interruptions.

Is the device suitable for both left- and right-handed users?

Yes, the symmetrical grip design with a 2K handle ensures secure and comfortable handling for all users.

Are accessories or spare parts available?

Yes, you can find spare batteries, cartridge holders, and other accessories in the Karl Dahm online shop. Our service team is happy to assist you with individual queries.
