Many of my remodel and painting jobs have one or more hard to reach yet still visible areas that require caulking but a standard caulking gun is just too lanky and awkward to get in there to do the job. You know the places: caulking the baseboard that runs behind a toilet or inside the adjacent wall pocket next to a freestanding vanity cabinet, or caulking in the backsplash on a tubdeck or countertop where the faucet handles are set a little too close to the backsplash to tip the gun into the corner for a clean finish. When access is too tight or otherwise limited to use my caulking gun but still requires an accurate, clean caulking job, you could run to the store and purchase a smaller squeeze-tube of caulk, but there’s a better way!
I reach for a plastic bag. Most any type of small plastic bag will do, and there’s almost always one floating around nearby on any jobsite, I will use anything from my lunch sandwich bag or that little bag that the screws or hardware that I just installed came in. Squirt the necessary amount caulk into one corner of the bag, press out the air, and twist off the opening until the caulk inside is under light pressure. Now cut the tip off the corner of the plastic bag to the correct size of your caulk-bead and you have a mini-“pastry bag” caulking tool that is very easy to control, accurate, and fits between your thumb and forefingers. This technique, which I use all the time, allows me to do a nice job caulking anywhere I can fit my hand.
