First, I should plainly answer your question, Can you really put caulk over new caulk?
I would say, Yes, Why not?
But if you want to do so, you’ve to keep in mind some important points about your caulk.
Things You Should Keep in Mind
Before caulking over a new caulk, you should first ensure that the previously applied caulk is not dried. So, you need to put the caulk over a new caulk so fast that the caulk applied in two different layers can mix between them and bind them like they’re applied at a time.
But If you want to apply caulk on a surface where the previously applied caulk has been already dried, you should take some precaution before applying the caulk.
- The caulk surface must be clean and dust free. If you see any dust on the previously applied dry caulk, take a soft cleaning cloth and rub over the surface gently.
- If there is any water or liquid substance on the caulk surface, make sure the substance is soaked with a cleaning cloth or a tissue paper. If you turn your fan on after cleaning the liquid, that will have a much better effect.
- After cleaning the previous caulking, you now need to apply the new one.
- When you apply the caulk to another caulk, make sure both are made of exactly the same ingredients. Otherwise, the caulks can be separated over the time and open up a leak once again.
What is Good in Applying Subsequent Caulk in New Caulk
You’ll find both pros and cons in every aspect of your life and this is no different. Good things are-
- Applying caulk over new caulk can allow you to seal comparatively deep and wide leakages.
- When you use the same type of caulk again in the same leak, it evident that the seal will be a lot stronger.
Negatives of Caulking on New Caulk
- It is a common problem that when you caulk over another caulk, they can separate from each other after some time.
- If there is any dust or water remains on the previously applied caulk, the caulk you applied later can cause leakage.
