Buying guide for BEST GROUT COATINGS

Robin Allday
Written by Robin Allday

Updated June 2023

Whether you’re renovating your bathroom, updating your kitchen or simply working on a home DIY project, a high-quality grout coating is a must-have item. The right grout coating can rejuvenate old tiles, restore their original color and protect them from further damage.

Grout coatings come in various colors, finishes and formulas, and they can be either pre-mixed or mixable. Some are squeezed directly onto the grout, while others need to be applied with a brush or a sponge. It's crucial to choose a product that is durable, easy to apply and resistant to mold and mildew.

Consider the color of your tiles and the look you want to achieve. Some people prefer a contrasting grout color for a more dramatic effect, while others like a coordinating color for a seamless look. Make sure to choose a grout coating that is water-resistant if you're working in a kitchen or bathroom.

WHAT TO KNOW BEFORE YOU BUY A GROUT COATING

Types of grout coatings
Grout coatings are used to revitalize old grout, restore its original color and protect it from further damage. There are several types of grout coatings you might encounter while shopping, including colorants, sealers and restorers. Understanding the difference is the first step to making the right choice for your tile project.

  • Grout colorant: This type of grout coating is primarily designed to change the color of your grout. It can be a great way to dramatically change the look of your tiles without having to replace the grout itself. Grout colorants usually come in a variety of colors to match or contrast with your tiles.
  • Grout sealer: Grout sealers are clear and designed to protect your grout from staining and damage. They can be applied over new grout to prolong its life or on older grout to prevent further damage. If you're happy with the color of your grout but want to protect it, a sealer is a good option.
  • Grout restorer: This type of grout coating is designed to both change the color of your grout and seal it. If your grout is discolored and damaged, a restorer can be a great way to give it new life.

Selecting the right grout coating

Consider the condition of your grout: If your grout is new and you simply want to protect it, a clear sealer is a great choice. If it's older and discolored, a colorant or restorer can give it a fresh, clean look.

  • Check the color match: If you're using a colorant or restorer, ensure that it matches or complements the color of your tiles. The wrong color can make your tiles look dated or out of place.
  • Consider the application process: Some grout coatings come in squeeze bottles or tubes for easy application, while others need to be applied with a brush or sponge. Make sure you're comfortable with the application process before you buy.

WHAT TO LOOK FOR WHEN BUYING A GROUT COATING

Resistance to mold and mildew
Look for a grout coating that is resistant to mold and mildew, especially if you're using it in a bathroom or kitchen. This will help your grout stay cleaner for longer and reduce the amount of maintenance required.

Easy to Apply
The easier a grout coating is to apply, the less time you'll spend on your tile project. Look for a product that comes with clear instructions and doesn't require any special tools or techniques.

Durability
A durable grout coating will protect your grout for a long time, reducing the need for frequent reapplications. Look for a product that is water-resistant and designed to last.

Good Coverage
A grout coating should provide good coverage, meaning it should easily cover the entire surface of the grout. This will give your tiles a uniform, clean look.

The right grout coating can make a big difference in the overall look and longevity of your tiles. Whether you're renovating a bathroom, updating a kitchen, or working on a home DIY project, investing in a high-quality grout coating is a smart choice.
