How to Seal a Caulking Tube for Reuse and Convenience
When taking on small projects at work or your home, it’s convenient to be able to save materials for later, like caulking tubes. Knowing how to seal a caulking tube for reuse can save you a lot of time and frustration when jobs come up, and it can even save you a little money, too!
What are the Challenges in Properly Resealing a Caulk Tube?

Many homeowners and professionals alike have used part of a caulking tube and developed quick, easy solutions to sealing a caulking tube, like using Saran wrap or an electrical wire cap or a nail. Unfortunately, they’ll usually find the tube is either entirely unusable or incredibly difficult to use within a short period of time.
All of these solutions tend to either get stuck on the caulking tube and need to be pried out or don’t provide a good seal and the tube becomes useless. The challenge is that you need to seal both ends of the tube well in order to keep things secure, but these materials either don’t make a good air seal or they end up getting stuck.
How to Seal a Caulking Tube for Reuse with StrapCap
The best kind of seal is something similar to the wire cap, because it sits on the nozzle without getting stuck; however, the cap has nothing holding it in place and falls off or loosens too easily. The reason something like StrapCap is so effective here is it provides a seal at the nozzle similar to the wire cap, but a marine grade bungee secures the tube in place to the base. The base seals the other end of the tube and keeps caulking fresh!
