Can You Caulk Over Grout?
To be precise, you can caulk over grout. But I’m saying you, this is not a good idea at all. Ask me why?
Caulk and grout are two similar kinds of products and their uses are also are of the same kind. But they are not the same. Grout is made out of compressed cement, sand, and water when caulk is made of different types of chemicals. Most of the caulks are made of silicone and other adhesive chemicals.
If you see a crack on a grout, you’ll see the crack on the grout is not similar kind of crack you see on the caulks. When the caulks are soft and smooth, the grout is harsh and sandy.
When you use caulk over grout, you’ll see the color difference between them which will look somewhat weird. The second drawback you’ll face is that the caulk won’t stick properly and will be separated after some days.
If you’re planning for a home improvement after some days and need a way to fill the crack for those days, you can use the caulk then. Using caulk over grout is not a permanent solution at all.
Can You Sand Over Caulk?
As I’ve discussed earlier that the caulk is not made out of any hard material like metal, sand, or cement, you can’t sand over caulk.
Sanding over caulk will ruin your hard earned good look of the home. As the caulk act like a rope when it is dried, you can see the whole line of caulk coming up when you touch an automatic electric sander.
If you’re thinking of a paper sand, this won’t work also. You’ll end up sticking sand on the caulk and roughing the smooth caulk surface.
If you see any extra caulk coming out of the surface or the caulk is moldy, use the caulk remover to remove the caulk. Thinking of removing mold? The hard work needed for removing the mold from the caulk don’t worth it.
Can You Grout Over Grout?
There can have some situations where you would feel that some new grout on older grout could be a better option than caulking over grout.
So, this common but less answered question must be on your mind also. Here is the answer-
Yes, you can grout over old dry grout. Before grouting over old grout you need to ensure that the old grout is sufficiently cleaned up for better bonding. If you use it on old dirty grout, the newly placed portion will not perfectly bond with the earlier portion.
The depth will also come into consideration if you want to put new on the old grout. Generally, anything higher than 1/8 inch is perfect for putting new grout on the older.
