Replace Grout Along Your Kitchen Counter With Caulk

3 Materials
1 Hour

After 3 years of watching the grout along my kitchen counter top crumble, I finally made time to fix that problem. The general rule is that caulk should be used whenever tile meets a solid surface, like a tub or a counter. Caulk sealant has more flex and holds up longer than grout during little shifts in that area, from heat, cold, water, etc. BUT, luckily, it's a pretty quick fix, most of the time. Watch the video to see how easy it actually is.

You can see that the grout between the tile and counter was crumbling away and starting to discolor.

I used a utility knife to carefully scrape away all the old grout. Be extra careful to avoid scratching the tile or counter. You can see how I do this in the video.

Grout will generally pop out pretty quickly, as long as it isn't an unusually thick or deep grout line. Old caulking can be removed the same way, BUT it will take more time and effort to remove.

I used Kwik Seal Plus Sealant because it's easy to use and every plumber that's been to my house lately has been using it. That's a pretty good recommendation in my book.

Use the caulk that matches your counter best. Sometimes clear caulk sealant is the best matching option, especially on dark counters.

You can apply a thin bead of caulk and push it into the joint with a wet finger. Be sure to wipe away any excess caulk before it can dry.

Sometimes you'll need to apply a second coat, after 24 hours. Apply that second coat whenever it looks like you didn't completely fill the joint. You want to make it nice and watertight. Again, you can see how I do this in the video.

I removed the old grout and finished the new caulk for the whole kicthen in less than an hour. Stop by my blog post to see more of my favorite easy DIY home maintenance tips and videos.

    Do you think it would also be possible to use on the kitchen floor?

    I keep caulking my bathtub and it peels away in certain areas. What am I doing wrong.

      I would think the area was not totally dry when you caulked. When I do something like this I tend to be overly cautious and set a fan up to blow on the area for a bit before I start to really ensure it is dry.

    Can I do this to the grout on my bathroom floor?

      I think you can do it, I would just be careful to only snip a tiny bit off to ensure a very thin bead to ensure no smear over the tiles. If you go to Home Depot or Lowes and look where they sell caulk and the like you will see that they sell all kinds of gadgets to make the job easier so look around and you may find a spreader designed for spreading caulk in tight spaces. If you do get it on the tile don't worry because you can get it off the tiles it is just a pain.

    I did it even before I saw this and it looks so nice and clean and new!!!! Kwik Seal is very easy to use too, once I open a tube I go around the house to see what else I can fix up (you can squeeze a little thru the opening and recap it to save, you do not have to use the entire tube in one sitting). I would start out with cutting a little bit off the tip until you see how to manage the flow and you can always cut off more for a wider bead. When you are using it plan to do your area, run your finger thru it with out interruption so it doesn't have time to set before you are done - move obstacles out of the way ahead of time to ensure a clear path, put on a rubber glove to be ready to run your finger thru it - just think ahead before you start so it ends up looking great when you are finished.
