Caulk and grout. They seem pretty similar. So, if your grout is starting to crack, can you use caulk to repair it? Well, yes and no. This article will tell you what you need to know.
Grout vs. Caulk: What’s the Difference?
Grout is a masonry product that starts out as a dry powder. Water is added to allow it to fill in cracks between tiles. It becomes rock hard when it cures.
Caulk is a semi-liquid product that is packaged in tubes and squeezed directly onto the required site. It retains flexibility after it cures allowing it to adjust to its settings. It is commonly used on angled seams.
Can I use Caulk Instead of Grout?
If you see cracks in your grout, you can put caulk on top of it as a temporary fix, but it will not be a good long-term solution. In a few weeks, or months if you’re lucky, you will notice it starting to flake or crack.
But if caulk is your only solution, you should take steps to ensure it stays in place as long as possible. Here is a breakdown of the recommended process.
- Remove the cracked or crumbling grout. This can be done with a handheld vacuum. The surface should be as clean and dry as possible before the caulk is applied.
- Caulk over the area. Once you are done, run your finger over the caulk pressing it firmly into the surface to ensure a firm connection.
- Wipe the area around the caulk so it doesn’t dry on the surface of the tiles.
Removing Caulk from Tile Grout
Caulk can temporarily work to cover holes in grout, but it won’t last long. Eventually, you will need to regrout to permanently fix your problem. But before regrouting, you must remove any caulk residue by taking the following steps.
- Apply a caulk remover to the affected areas. There are 3M and gel-based removers and either will work. Lather them over the tiles and wait 2-3 hours to allow them to loosen the caulk.
- Use a caulk remover tool or utility blade to remove the caulk. It should be coming off in long strips. If it’s chipping off, apply more of the remover solution and try again.
- Take a putty knife and remove any residual caulk.
- After an initial dusting of the area, use a small towel soaked with alcohol to wipe it clean. This will prevent the growth of mold and mildew.
If you are noticing issues with your grout, caulk can be a good quick fix, but it won’t last forever, and you will eventually have to regrout. Grout Experts will assist you with your regrouting needs. Contact us to get your tiling in good shape.
