Milwaukee Cordless Caulk / Adhesive guns (M12 / M18)

[RDawson]

Looking to see if anyone on the forum has had any practical hands on with any of the Milwaukee cordless Caulking / adhesive guns. I am particularly interested in thoughts / feedback on the M12 (12v) line but please feel free to chime in if you have had hands on with the M18 (18v). The gun portion of M12 and M18 seem to be consistent across their lines and I believe it is just the format of the cartridge that varies between them. [ 20oz Sausage Alum & Clear Plastic | 10oz/295ml Cartridge | 20oz / 590ml Cartridge | Quart size cartridge. ]


Thanks for any info you are willing to share.

I have a great deal of experience with the gun that uses the 10.5 standard caulk tubes. As a superintendent on commercial jobs I would do the sealant work whenever time in the schedule permitted.
From masonry control joints to exterior windows and doors and all the other miscelaneous sealing and caulking that came up. As I recall the 12v unit cost about $250. It was absolutely worth it. There is a little bit of a learning curve. After some practice you can run a joint with no signs of "pumping" like you often get with a standard gun. It is critical that you puncture the tube because the gun doesn't "know" you haven't and will push right through the bottom of the tube resulting in a big clean up mess. Learned that a couple times the hard way. The company recently closed down and when the tools come up for sale it's the only one I'd be interested in. I don't think you'll be disappointed if you get one.

My gun is the older style 12 volt that took the Ni-cad batteries. I bought mine from a Milwaukee service center in Los Angeles as a refurbished cartridge gun but ordered the parts to convert it to a sausage gun, which is what I primarily use so I'm able to switch to either type if needed. I use mine mainly to shoot structural silicon joints in glass curtain walls and storefronts and it does a great job of it. You could also use the 14 volt battery in my gun as well. I'm not sure but I seem to recall the newer model having a variable speed control,that would be handy in some situations. When you load the gun and pull the trigger the sealant doesn't appear to come out all that fast but you'd be surprised how fast you can make a mess if you don't move fast enough so some practice beforehand might not be a bad idea. We will often mask off the immediate area with tape before shooting the joint to catch any excess from the gun or from tooling the sealant into the joint. Hope this helps. Carlos
