Why You Need Caulk Caps

One of the most common frustrations in any caulking project is returning to a tube only to find the tip has dried and clogged. These protective covers eliminate that problem entirely. Simply cap your tube when you're done, and it stays workable for your next session — no digging out dried caulk, no wasted material, and no trips back to the store for a new tube.
