Caulk has been used for a long time now to seal cracks on a variety of materials and equipment. Actually, caulk has become so popular because of its affordability. Caulk also takes the least amount of time to dry which is a big plus for those who might need to carry out some sealing activities urgently.
On the other hand, the fast drying time can be so frustrating especially if you haven’t used the entire caulk during the sealing process. At some point, I felt like throwing the tube away because I found the caulk unable to be used when I wanted to caulk again over the existing caulk on my RV.
Have you ever found it difficult to use caulk a second time? Worry no more as you are going to learn how to seal caulk tube, therefore, preserving your unused caulk. Even though caulk is relatively cheap, getting an ideal caulk brand is difficult and it is important that we save the remaining unused caulk for future jobs.
You might find yourself in a critical situation like at a campsite that is far away from shops and the little well-kept caulk could be of great help. This makes the above topic a very important one that you really need to take note of.
Ways of sealing caulk tubes
Here are some of the ways you can use to help render your caulk useful a second time after the first use. They are very simple and straightforward but very important in the long run. Take a look at them below.
1. Use of duct tape
A duct tape is one of the materials you can use to seal caulk tube after use. You just need about 2 inches of the duct tape to get the job done. Isn’t this something that you can easily get? Of course, duct tapes are easily and cheaply available.
How then do you get going? Well, just place the caulk’s nozzle end in the middle of the side that is sticky. You will then proceed to have the tape folded down along the nozzle’s long sides. This means that the two sticky ends will stick together after which you will then press the duct tape around the nozzle.
It is that simple! Can you imagine that? You will end up saving a lot by embracing this method of sealing a caulk tube.
2. Use of waterproof wire nuts
Waterproof wire nuts have also been found to be of great importance when it comes to sealing of caulk tubes. The wire nuts safely lock the caulk tubes’ nozzles, therefore, protecting the remaining contents from drying up.
This is another process that has been tried, tested and found to be helpful as well. You can try it out and see if it will help preserve your caulk for future use.
3. Toilet wax ring
A toilet wax ring is another thing you can use. It is generally cheap with a single piece going for less than a dollar. Once you have acquired the wax ring and you are done sealing using the caulk, have the caulk’s tip pushed into the wax ring. The wax does a perfect job in ensuring that the caulk is sealed without any losses experienced.
The 16D penny nail is another great solution to this notorious problem. The penny nail is to be pushed through the open hole and a duct tape used to close the area around the opening. Please take note that the nail should be long enough. Besides, it needs to tightly fit for the desired results to be found.
If the time is ripe to reuse the caulk, just remove the nail and tape and a channel will have been produced through the already dried caulk in the nozzle. This in return allows the fresh caulk to come out of the tube.
5. Use of a circular plastic material and a source of heat
Before you use these materials, you first have to ensure that the caulk’s nozzle is clean. Thereafter, use a lighter, for example, a candle to heat the circular material’s center. The source of heat needs to be moved in a circular motion until the material becomes transparent.
Make sure the transparent area is about 2.5 inches in diameter. Once the plastic material has become transparent due to the heat, push it quickly over the caulk’s tip. This soft material is going to stretch over the caulk forming some sought of a molded cap.
One area that needs close attention to is the type of material that has been used to make the material. If it is the same material as the tube’s nozzle, a bond might be formed between the materials at times. But if the materials aren’t the same, the resulting molded cap will be a tight-fitting one.
After the cap has cooled down, trim it. You can even add some tape around the new cap’s base. This technique isn’t meant to keep the caulk fresh forever but rather just extend its lifetime.
6. Leaving a blob of caulk on the tube’s tip
There are also some other less familiar ways of sealing caulk tubes that have been improvised to help in extending the period within which your caulk is fit to be used. You can leave a large blob of caulk on the tube’s tip for example.
After it has dried up, it seals the other parts of the tube. The blob should be large enough so that whenever you need to use the caulk, you only need to pull the blob off. I’ve tried using this technique in the past and it really works fine.
7. Use of electrical and packing tapes
There are also other caulk users who have resorted to the use of electrical tapes to seal caulk tubes. However, you need to make sure that it is first relieved of air and pressure. The product will thereafter stay in good condition even for a whole year.
The electrical tape eventually falls off but this only happens after a long time; actually, the caulk will be useless at the time of the tapes falling off. The tape is always easier to spot and is a perfect reminder to any user that the tube has been used before.
Packing tapes, on the other hand, can be of great use as well. Just fold a 6” piece of packing tape over the tip of the tube in a way that the usually sticky sides face one another. Press the tape down, then have it twisted to give a strong seal that is easy to remove on the other hand.
How to use a silicone gun or caulk gun
The above-mentioned ways of how to seal caulk tube are just but a few among the many other ways available out there. They aren’t 100% effective though and you need to choose whatever will work for you. Most of them will not keep the caulk fresh forever but just for a considerable amount of time.
This will save you the cost of buying caulk every time. You won’t even have to be wasteful knowing that the caulk will not last long after the first use. Take note that some of the ways of sealing caulk tubes discussed here can be combined for the best results to be achieved.
