12 Sep Can You Put Grout on Top of Old Grout?
You have been meaning to re-grout your tile for months now, but the idea of removing all of that old grout is just too daunting. Surely there must be an easier way? Can you just put new grout on top of old grout?
The short answer is yes, you can put new grout on top of old grout. However, there are a few things you should know before taking this approach.
1. You Need a Grout Removal Tool
Use the grout removal tool to strike out old grout, making sure the depth is at least 2 millimeters. This is about the thickness of two dimes stacked one on top of the other. Once you have removed all of the old grout, make sure to cleanse thoroughly so there will be no dust or debris that interferes with new grout application.
2. The New Grout Will Not Adhere As Well To The Old Grout
This means that it is more likely to crack or chip over time. If your old grout is in decent shape, this may not be a big deal. However, if it is already cracked or crumbling, you are better off starting from scratch.
3. You Will Need To Use A Different Type Of Grout Than What Was Originally Used
For example, if your old grout was sanded, you will need to use an unsanded grout for the new layer.
4. You May Need To Use A Bonding Agent
A bonding agent helps the new grout adhere to the old grout. This is particularly important if your old grout is in bad shape.
5. You Will Need To Take Extra Care When Applying The New Grout
When applying the new grout, be sure to spread it evenly and press it into the cracks between the tiles. You may need to use a putty knife or other tool to help get the grout into all of the nooks and crannies.
6. The New Grout Will Be Thicker Than The Old Grout
This can be a problem if your tiles are not level. Be sure to check the level of your tiles before applying the new grout. You may need to use a thinner layer of grout in order to avoid problems with uneven tiles.
7. You Will Need To Cure The New Grout
After you have applied the new grout, you will need to cure it. This means that you will need to let it dry for a period of time before using the area. Curing times will vary depending on the type of grout that you use, so be sure to read the instructions on the package.
8. Be Careful When Cleaning Up
Grout can be difficult to clean up if you let it dry. Be sure to clean up any grout that gets on your tiles or floors before it dries. You may need to use a putty knife or other tool to scrape up the dried grout.
Consider Epoxy Grout
Epoxy grout is a newer type of grout that has many advantages over traditional grout. Epoxy grout is much stronger than many other types of grout.
It is also easier to clean than traditional grout.
