A common mistake is to cut off too much of the caulk tube tip, leaving a hole that’s way too big for most interior caulking work. When you’re filling small cracks to prepare for painting, cut the tip carefully to keep the hole tiny—about 1/16 in. in diameter. The tiny hole lets out just enough caulk to fill typical small- to medium-size cracks. For larger cracks, make a second pass or keep a second caulk gun on hand, loaded with a tube that has a slightly bigger hole. Keep the caulk gun moving quickly along the crack as you squeeze the trigger. This, combined with the small opening in the tip, will give you a nice caulk joint that needs very little cleanup. A quick swipe with a dampened fingertip will leave a paint-ready joint.
Disguising Caulk on Concrete
If you’re caulking concrete, either to fill a crack or to seal it around the edge, you can make the caulk almost invisible. Simply dust the caulk with dry concrete mix while it’s still wet. When it’s dry, brush away the excess, and the caulk will virtually disappear.
Reusable Caulk Tube
How often do you have dry caulk stuck in the tip of the tube but know that there’s a lot of fresh stuff behind it? Get to the fresh stuff by first cutting two slits along the tube,on opposite sides, with a sharp utility knife. Pry out the dried plug of caulk.Then wrap the tip with duct tape, put the tube back in the gun and use up that caulk.
