I'm Terry with Towers Murray Plumbing, here to show you how to repair shower caulk. Now when repairing shower caulk, there's really not a repair. What you need to do is replace it if you're getting a leak behind the shower. So, the first thing you want to do is take a pocket knife, better off if you can get a razor knife. There are tools these days to make repairing replacing caulk easier. It helps you pull it out. What you'll want to do is take and cut that and then you'll scrape it out. Now sometimes you can take a putty knife and pull that as much of that old caulk out as you can. Now once you get that out you'll want to take, the best thing is a little bit of rubbing alcohol and clean that up. Now we're just doing a short section here but if you're doing a whole tub you'll want to have some time. Once you get this all cleaned up, cleaned out, you'll want to take the rubbing alcohol, clean it up. You'll need to let that dry. You want it as dry as possible. So if you can let it sit 24 hours, now some of the tools that you'll need when you're doing this is you'll need a sponge, a damp sponge or a damp rag. You'll put the caulk on, take your finger and smooth it out. Once you get that new caulk put in there, that new caulk will also need at least 24 hours to dry. Now other tools, other products that can make life a little bit easier, there are some caulk softeners or silicone softeners on the market these days. These if you put these on it will soften that caulk, make it a lot easier to remove it. And again, I'm Terry with Towers Murray Plumbing and we've showed you how to repair shower caulk.
