Steps To Fix Hairline Crack In Shower Base
1. Inspect The Hairline Crack(s)
Before working on repairing a hairline crack in the shower base, you have to pinpoint how many you’re dealing with.
Sometimes, you spot one hairline crack and quickly realize there are more spread throughout the shower base.
The goal is to find all of them before creating a plan to fix everything.
If there is one hairline crack, this is ideal as that will be easier to fix. However, as long as you spot all of them, you will be good to go with the repair.
2. Wipe The Surface Dry
When putting together a shower pan repair kit, you have to begin with a dry cloth.
This cloth is going to be used to remove any moisture that is present on the surface. Since you are working with a shower base, there is likely moisture settled on top that has to be removed.
Look to wipe everything and ensure you don’t have wet spots around the base.
These need to be removed or the caulk is not going to take hold when you begin repairing the hairline crack.
3. Apply Rubbing Alcohol And Wipe The Surface Again
It is also important to think about the soap residue that sits on the surface.
This often gets ignored because you are solely focused on removing moisture from the shower base.
While the moisture is a problem, it is the soap residue that can become a real challenge to navigate around.
The best option is to apply rubbing alcohol to the area and wipe the surface using a clean cloth.
You don’t have to wipe the entire surface while doing this.
Just wipe the area that is going to be repaired. The rubbing alcohol will settle and allow you to wipe off any soap residue that is present.
4. Apply Caulk On Top Of The Crack
You are now going to apply caulk on top of the hairline crack.
The goal here is to make sure you are applying carefully and not damaging the surrounding surface.
You will want to use a caulking tool for this purpose.
Once done, make sure it is spread with your finger or a small tool that will ensure you don’t make a mess in the shower base.
How long do you have to wait once the caulk has been applied?
It is best to wait at least a few hours as that is going to let the caulk take hold. This is important as you don’t want moisture getting through the caulk as that will render it useless.
These steps are all you need when learning how to repair a hairline crack in the shower base.
