PG100 1/10th Gallon Cartridge Air Caulking Gun

I bought this item last year, after we bought our new home, and I knew I would be painting the entire interior. A professional painter had suggested putting a fine bead of caulk around all the ceiling/wall seams in order to get a clean line when painting. OMG! I'm 58 years old and I knew my hand would fall off doing that much caulking with a regular gun. So, I researched and ended up buying the Caulk Master gun. It took a bit of experimenting and practice to get the pressure right and to get the opening on the tube small enough, but I did master it within a few tries. What a wonderful work saver! This thing works great for painter's caulk. I can lay down a perfect, fine bead with little effort. Yes, it does occasionally spit an air bubble when I get close to the end of the tube. Yes, the hose coupling is a bit of a pain. I just hold it with my left hand to keep it from swinging around. A longer hose would be nice. I have no idea how it works for thicker caulks/adhesives, but it is great for softer products. Somebody else said it was the Cat's Meow. Well I am adding the Cat's Pajamas to the superlatives.

I WAS HAVING FUN WITH, MY DAD I WORKED TOGATHER ON HOMES 25 YEARS. SO I GOT THIS IT WAS GOOD FOR 6 TUBS, I MADE SURE IT WAS CLEN, AIR PSI, WAS RIGHT. THEN IT STOP,, IGOT SAMS TUB OUT OF AIR GUN PUT IT IN A HAND GUN, TUB CAULK WAS WORKING GOOD. ALL TUBS OF CAULK I GOT AT LOWES AND LOOKED AT THE DATES ON EACH ONE. THIS BAD THING NOT BECOUSE IT STOP ON ME I READ ALL ABOUT IT WHAT WAS SAID HOW THAY USED IT. I HAVE $40.000.00 TOOLS, BUT THIS ONE GOT ME TDHILL.

Might be ok for the casual user, but we bought this to use in a production environment and the trigger set up is definitely not easy on the fingers.

I've never written a review on an amazon product before, though I see my wife has. I'm going to make this my first, I'm impressed.I've put several tubes of caulk through this gun and I like it more each time I use it. I'm residing my house with Hardi-plank and using the solvent based caulk recommended for it. This caulk is thicker than other caulk I have used in the past. I have had the pressure up around 40 psi to get the size bead I want at the speed I feel comfortable with. No complaints from the gun. As I was working in the soffit area, I started to get frustrated with the lack of space, not being able to get the angle with the gun that I felt I wanted. I was second guessing my purchase when I realized that this gun is about as small as it can get. There is no rod sticking up past the grip to get in the way. A little creative bending of the nozzle and positioning of the gun will get me where i need to be. But wether the tube is full or empty, the gun is the same size. This is both good and bad, see criticisms below.The directions indicate that you should cut the tube straight across rather than on an angle like I'm familiar with. I think this is because there is no rotating the tube to get the angle to match your work once it is installed in the gun. As others have noted, you do need to push fairly hard to get the bayonet housing to lock in place. Once it is, the only way to change that angle is to take it out and reinsert it into the gun with a new angle of attack. Having proven this to myself with my first tube, I followed the instructions on the second. With a little bit of practice I was getting very consistent beads that needed very little tooling to finish. The trigger allows fairly fine control, and since you aren't trying to hold the gun steady while squeezing the pump, you can focus on controlling the bead.I did have one tube "misfire" on me. After inserting a new tube, and starting a bead, the gun would continue to dribble after releasing the trigger. After only a few feet of bead, the tube started releasing air from the tip. I opened it up to find that the plunger that comes in the tube had cocked sideways and allowed air into the caulk cavity, rather than staying straight and forcing out the caulk. Putting the tube into an old fashioned caulk gun and carefully straightening out the plunger restored proper function, including stopping the flow of caulk when releasing the trigger.As another review noted, a local (like within arms reach) pressure regulator would be very useful. No dig on the tool, just something to be aware of, and perhaps purchase.I think I can only find 2 problems with this gun:1) Relating to the fact that there is no plunger rod, there is no way to tell how much material is left in the tube. That plunger gives you a visual indicator that you are getting low, allowing you to decide If you are going to run this last section or reload so you can do a high visibility area in one continuous bead (or finish this one last piece of subfloor before knocking off for the night.) This isn't really a big deal, and I much prefer being able to get into tighter spaces, but I did notice.2) The gun is hard to put down. While it is fun to use, occasionally you need to stop to tool the bead, move the ladder, whatever. There is no hook, lanyard or strap to do this with. The temptation is to hang it by the grip, but this may activate the trigger, spooging caulk (ummmm - or so I would assume). Sticking the nozzle through a handy hole in the ladder is precarious at best, especially if you're going to move the ladder. I solved this problem with a Husky brand version of a tool lasso like the one (possibly) linked here:http://www.amazon.com/Werner-AC58-TL-Lock-In-Tool-Lasso/dp/B003Z6QBRC/ref=sr_1_sc_1?ie=UTF8&qid=1353990843&sr=8-1-spell&keywords=Werner+tool+lasoIf the link does not work, search Amazon for "Werner tool lasso"I found this gun to exceed my expectations. I really am sort of enjoying running caulk rather than dreading it. If I can get to the point where I can avoid tooling the caulk and having my fingers perma-stuck to everything in sight, I will be ecstatic.

It's too bad this item is no longer offered here - it can transform a high-volume caulking or adhesive job from a chore into a pleasure. It seems a little expensive, and it's probably impractical to haul hoses around for minor caulking jobs, but if you have the right application, it's a godsend.One of the nicest aspects of it is that it is so clean and simple - just air pressure pushes the back end of the tube and nothing really gets caulk on it. It's best if you have your pressure regulator (you really need one for this tool) near where you're working so you can fine-tune delivery as necessary.To tell you the truth, I owned this tool for quite a while before I ran across an application for it. I guess I could've used it when caulking windows etc., but at the time it seemed easier just to grab a regular caulk gun.This winter I had a job that involved long beads of construction adhesive over and over again. In the 30 something degree temperatures at the site, squeezing tube after tube of the thick material was starting to take it's toll on my forearms. Luckily I had compressed air available, so I pulled this thing out to see what it can do.What a difference! Now I look forward to the application chore - it's more of a break than a chore now - just a gentle squeeze and go as fast as you can while keeping your bead straight. I think this is the best application for this tool - lot's of volume and in a location where air hoses are easily available. The squeeze gun is still probably better for jobs that are less accessible and where precise control is important.

I bought this gun enen though I read other people's negative reviews and agree with them that it is poorly engineered. The trigger mechanism is all or nothing so the only way to control the flow rate is by adjusting the aiir preasure at the compresser. It doesn't have a mechanical plunger to push the end plug through the tube and instead pumps out the calk with air so every now and then you get a big burst of air in the calk. I resorted back to a hand gun to finish my job and realized that I had much better control of volume this way. It might be useful for applying something thick like construction adhesive when neatness didn't count but otherwise it's not a useful tool.
