Seal Tile and Grout with Confidence
Whether a beautiful kitchen backsplash or a durable shower wall, the perfect tile will transform your project into a masterpiece. However, regardless of the project, you must learn about the basics of tile installation, such as how to seal tile and when to seal grout.
As your go-to tile supply store, the team of experts at St. Louis Tile Company provides you with luxury tiles at everyday prices, and essential tips so you can seal and tile your grout correctly and confidently.
When to Seal Grout
Before we teach you how to seal grout, you must learn when to seal grout as well.
After installing tile, you must wait at least 48 to 72 hours for the grout to dry and cure completely. If your grout lines are cracked or chipped, you will need to touch up the grout. You must also wait for an additional 48 to 72 hours before applying the sealer.
How to Seal Grout
Clean and Repair Grout
Before applying a sealer, you must ensure your grout is dry and free of any dirt or dust. Clean your grout thoroughly with a sponge, scrubbing brush or toothbrush.
You must also repair any cracks or fractures in the grout lines. Otherwise, you will seal in the dirt and damaged seams, which will be impossible to remove.
Tackle one grout line at a time. You should only move onto the next area when there is a noticeable improvement in the color of the grout. When you are finished, allow the area to dry for at least 45 minutes before applying the sealer.
Choose Your Sealer
When choosing a sealer, you must consider the type of tile you are using and where you intend to install it, whether a kitchen, bathroom or elsewhere.
All sealers are different. Some sealers work best with marble and ceramic tiles, while other sealers handle more moisture better than others.
Typically, you can use either a penetrating sealer or a membrane-forming seal for your project. A penetrating sealer is ideal for damp areas such as bathrooms and showers, while a membrane-forming sealer works well in the kitchen.
Choose Your Sealer Applicator
It is crucial to choose the appropriate applicator for your project. You can use a variety of applicator tools, such as a foam paintbrush, a small roller, or a paint pad. However, not all applicators are the same - they have different purposes and the applicator you choose should depend on your specific project.
For example, if your grout lines are thin, you can seal larger sections of your walls or floors with a sponge by wiping over both surfaces at once.
If you have glazed tiles, you can seal the grout lines with an applicator brush or a specialty applicator bottle.
Apply the Sealer
To apply the sealer, it is ideal to work slowly and deliberately.
With your applicator of choice, start in one corner and apply the sealer in small areas at a time, working left to right. You need to cover every corner and apply the sealant in smooth, even coats.
By working systematically, your sealer will provide better protection and your grout lines will appear more consistent.
It is also important to remove the sealer from the tile before it dries completely. To avoid this issue, keep a dry cloth nearby to wipe off the excess sealer when necessary.
Apply the Second Coat of Sealer
Let the first coat dry for an hour before applying a second coat. Depending on the grout sealer you choose, allow 24 to 48 hours for the second coat of sealer to cure.
After the second coat completely dries, test the surface with a few drops of water. If the liquid beads up into droplets, you do not need another coat. However, if your grout does not absorb water at all, apply a third coat to ensure quality results.
What to Buy to Seal Grout
Before you begin, you must have the following materials on hand:
- Grout sealer
- Cleaning solution
- Grout sealer applicator (paintbrushes, foam rollers, sponge)
- Clean lint-free rag
