Why Is Silicone Caulk Not Curing? (Solved)

Silicone caulk is supposed to cure over time, which means it stops being sticky and begins to dry as required.

In most cases, this is a seamless process that does not take a long time to complete.

If silicone caulk is not curing as intended, it’s important to figure out what is going on and how to speed up the process as soon as possible.

If silicone caulk is not curing, start by setting up a humidifier in the space. Once done, let it run for a few days, monitor the caulk, and ensure the door is closed as the humidifier runs.

These steps will help with curing silicone caulk and make sure it does not have the same moist texture that you are hoping to get rid of.

Here is what you have to do to dry silicone caulk that’s not curing.

How To Dry Silicone Caulk That’s Not Curing

1. Set Up A Humidifier

You will want to begin by understanding the humidity levels in the room.

This can be a real issue as it will slow how fast the silicone caulk dries. You will want to take the time to think about this to make sure you are on top of things.

If you don’t set up a humidifier, you will not see appropriate results.

A humidifier is a great way to regulate how much humidity is in the space. If you take the time to enclose the space (i.e. close the door), you are going to see better results too.

This is something you are going to want to test.

You will also want to continue to monitor how well the humidifier works when it is set up. You will start to notice the silicone caulk change as the humidifier runs and that is a good sign.

2. Increase The Waiting Period

How long have you been waiting for the silicone caulk to dry?

This is an important detail to go over as you will want to keep track of the time spent on this part of the process.

For the most part, you will need to increase the waiting period by at least a day or two. You can go beyond this point if you start to notice positive changes when the humidifier is set up.

As long as there is some form of curing taking place, you will know it will work out as long as you wait.

Being patient during this part of the process is beneficial as each environment is different. This includes the humidity in the space.

3. Close The Door And Windows

You will also want to help the humidifier when it is time to run it in the room.

To do this, you are going to want to enclose the space.

This can be done by closing any door or window that is open in the room. This is going to help let the humidifier run within a controlled space.

Otherwise, it’s possible the airflow is not going to help with the curing process or it will slow it down further.

The best approach is to close the door and then let the humidifier do its job as it should.

4. Monitor The Caulk

The last tip is to make sure you are monitoring the silicone caulk for results.

Do not assume it will start producing results and dry effectively.

You might have to make additional changes including where the humidifier is set up. However, monitoring the silicone caulk will let you remain on top of this and see any changes that have been made during the curing process.

What you are on the lookout for is to make sure there is a change as each day goes by.

If you notice it is curing, let the process unfold.

If you don’t notice a change after 2-3 days, it’s time to look at re-applying the silicone caulk.

Final Thoughts

These are the steps that matter if silicone caulk is not curing properly.

If silicone caulk is not curing properly, start by setting up a humidifier in the space. To do this well, close the door/window, let the humidifier run, and make sure to monitor the results in the coming days.

This will likely take at least a day or two for results to come. In some cases, you will need to wait at least ten days and that is a possibility you will want to be prepared for.

As long as you are noticing results with the humidifier, let it run in the background. This is how you are going to speed up the process as soon as you want.
