While working on a project installing 'faux" rock panels to my home I became pretty frustrated with the caulk gun I had owned for years purchased from one of our local "big box" stores. The faux rock panel installation calls for construction adhesive being applied to the back portion on these 24x48 inch panels. I had 110 of these panels to install!!! My old gun took a lot of effort to get the adhesive out of the container, not to mention this project was taking place in November so the temps were making the adhesive tubes colder and the adhesive inside a bit harder to work with. I finally gave up after two days and thus began my research to find the bigger better caulk gun.
In steps the Newborn 250 caulking gun. This thing has a whooping 18:1 thrust ratio which basically means, its pushing out whatever is in the tube you've loaded up into the gun's cylinder/frame fast, easy and with little effort!!!!
It's an all steel construction which makes it heavy duty and ready to stand up to the most strenuous caulking job you have planned. Thus far I've applied construction adhesives, roofing tar, interior and exterior silicone caulks and I can only imagine it could handle anything else I might throw at it as a home DiYER:-)
Because of the awesome thrust ratio, exertion on my side is minimal as the caulk flows easily and evenly from minimal pressure applied to the caulk gun's handle. I like the fact that it has a substantial piercing rod attached to it to both puncture the caulking tube as well as piercing and cleaning out old clogged up caulking tube tips and caps. The gun also features a caulk tube cutter to snip off the tip of new tubes.
As I stated earlier, the construction IMO is pretty superior to the guns you'll find at most stores and the handle is so well made and heavy duty it actually feels very comfortable and sturdy in your hand during use. And the solid pressure rod that does all the work is not only well made but visibly thicker and pronounced to help ensure that force is concentrated where it needs to be; at the base of the caulking tube to give you a full even pressure and steady flow of material.
This thing is a BEAST!!! and without a doubt money well spent! I'm basically doing a full house renovation and this gun has seen a decent amount of action thus far and has yet to fail or disappoint.
Do yourself a favor and buy one, you won't regret it:-)
