How to Re-Caulk a Bathroom


Whether around the bathtub, sink, or shower, caulking is never going to remain watertight forever. Yours will eventually start to show signs of wear, then begin to crack, shrink, or discolour. This means that it isn’t doing its job anymore, so you need to re-caulk in order to prevent water damage from occurring.

Firstly, you’ll need to assess the caulking to make sure it needs to be removed. Certain areas are more likely to fail than others, so check places which are frequently wet, those which bear pressure, and those which are hit directly by the stream of water from your shower. If there are any signs of damage, it’s time to get re-caulking.

You’ll need to get rid of the existing caulk first, and the difficulty will vary from case to case. You may be able to remove it using a putty knife, but a Stanley knife can be useful to scrape any remaining bits away from your tiles. There are also caulk softeners available to speed up the process. Trying to bond new caulk to old caulk won’t often work, so make sure you get rid of it all. Use the smallest nozzle on your vacuum to remove the debris, then prepare the tiles for a fresh application by moistening a paper towel with rubbing alcohol and cleaning away any remaining residue.

You’re now ready to apply the new caulk. Once you’re set up with the caulking gun drag the tip along in one swift motion which is consistent with the speed at which the caulk is coming out. Wipe the tip clean after each length, then continue along the perimeter until all edges are re-caulked.


If excess blobs emerge, just dip your finger in water and run it along the caulk line to smooth things out. Keep re-wetting your finger whenever you need to do so. If you find a gap where not enough was applied, you should be able to wipe excess caulk from another area to cover it. If not, add a small blob and then smooth it in using a damp paper towel to make it seamless.

Your bathroom is now re-caulked. All you need to do now is pack up the equipment, wait for everything to dry, and then get back to life as normal. Simple.
