To our view installing caulking is an arduous and time consuming task. The use of pneumatic or battery powered tools for installing caulking has been a trade off we've been juggling between the cost and maintenance of the tool versus the time and effort potentially saved doing the work. In our case faced with a job installing a lot of caulking from standard sized cartridges it justified the expense of finding an alternative to conventional "hand squeeze" caulking guns.
We purchased the Cooper Tools "Caulk Master pg110" air powered caulking gun to replace a cheaper air caulking gun the "Campbell Hausfeld PL 1558" that we first purchased but would not push tubes of 3M marine caulking that we needed to install.
The "Caulk Master pg110" is an air powered caulking gun that allows cranking up the air pressure to a maximum of 100 p.s.i. much higher than most of the pneumatic caulking guns on the market. The "Caulk Master" is a lighter tool compared to the "Campbell Hausfeld" is nicely machined has a larger and easier to squeeze trigger and has a three foot air hose "pigtail" ready to accept a 1/4 quick disconnect coupling. The good news for us is that the "Caulk Master pg110" pushes the heavier 3M Marine Caulking with ease (cranked up to around sixty p.s.i.). The "Caulk Master pg110" was more expensive than the Campbell Hausfeld unit but hopefully will give many good years of service.
With a wide variety of air pressure settings available the "Caulk Master pg110" will likely push silicon elastomeric and thick butyl rubber caulking as well as construction adhesives with no problem.
On problem we've noted about the "Caulk Master pg110" is that the outside tube holder (the part that comes off to insert the caulking tube) is hard to reinstall back onto the base of the gun once you add the caulking cartridge. The circular bottom of the caulking tube fits tightly against a rubber gasket in the gun body that seals the entering air pressure but putting the thing back together after installing a new caulking cartridge requires a lot of pressure to the point where we wound up putting the back of the gun against the floor in between our shoes for lateral support of the gun base and then pushing the tube cover and caulking cartridge into the base using our body weight! It takes a surprising amount of force to get the component parts to mate and lock together.
The extra pressure that was needed to install caulking tubes could be because the tool is new and needs to be broken in or it could be because of the potential higher operating air pressure of the pg110 requiring tighter fitting components. For us this is not a deal breaker but be aware that if all the Cooper "Caulk Master pg110" guns are this hard to load with caulking and if it doesn't "break in" and get easier with time you will need a couple of good strong arms to install the caulking cartridges into the caulking gun.
Cooper Tools provides a detailed parts list and it appears that parts for this tool are readily available so as things wear out the Caulk Master can likely be kept working for many years to come.
