Why You Should Seal Your Grout and How to Do It Right

Grout is the material that fills the gaps between tiles on floors, walls, countertops, and other surfaces. It's usually made of cement, sand, and water, and it comes in different colors to match your tiles. Grout is essential for keeping your tiles in place and preventing water damage, but it also has some drawbacks. Grout is porous, which means it can absorb dirt, stains, mold, mildew, bacteria, and other contaminants over time. This can make your grout look dirty and discolored, and it can also pose health risks for you and your family. That's why grout sealing is important.


Grout sealing is the process of applying a protective coating over your grout to make it more resistant to moisture, stains, and bacteria. Grout sealing can extend the life of your grout and keep it looking fresh and clean for longer. Grout sealing can also enhance the appearance of your tiles by making the grout color more uniform and consistent. In this blog post, we'll explain why grout sealing is important, how to do it right, and how to get professional help if you need it.

The Benefits of Grout Sealing

Grout sealing has many benefits for your home and your health. Here are some of the main reasons why you should seal your grout:


  • Grout sealing prevents water damage. Water can seep into your grout and cause cracks, mold, mildew, and rot. This can damage your tiles and the underlying surface, leading to costly repairs or replacements. Grout sealing creates a waterproof barrier that prevents water from penetrating your grout and causing problems.
  • Grout sealing prevents stains. Grout can absorb spills, dirt, grease, soap scum, and other substances that can stain it over time. This can make your grout look dull and dirty, and it can also affect the color of your tiles. Grout sealing prevents stains from setting in by making your grout less porous and easier to clean.
  • Grout sealing prevents bacteria growth. Grout can harbor bacteria, germs, fungi, and other microorganisms that can cause odors, allergies, infections, and diseases. These organisms can thrive in moist and dark environments like bathrooms and kitchens. Grout sealing inhibits bacteria growth by reducing moisture and creating a sanitary surface.
  • Grout sealing improves aesthetics. Grout can fade, crack, chip, or peel over time due to wear and tear, exposure to sunlight, or harsh cleaning products. This can make your grout look uneven, old, or ugly. Grout sealing restores the color and texture of your grout by filling in the cracks and gaps and creating a smooth and uniform finish.

How to Seal Your Grout

Grout sealing is not a difficult task, but it does require some time, patience, and attention to detail. Here are the basic steps on how to seal your grout:


  • Clean your grout. Before you apply any sealer, you need to make sure your grout is clean and free of any dirt, dust, grease, soap residue, or mold. You can use a mild detergent or a specialized grout cleaner to scrub your grout with a brush or a sponge. Rinse well with water and let it dry completely.
  • Choose your sealer. There are different types of grout sealers available on the market, such as penetrating sealers or topical sealers. Penetrating sealers soak into the grout and form a protective layer below the surface. Topical sealers coat the surface of the grout and create a shiny finish. Penetrating sealers are more durable and effective than topical sealers, but they are also more expensive and harder to apply. You should choose a sealer that suits your budget, preference, and type of grout.
  • Apply your sealer. You can use a brush, a roller, a sponge, or a spray bottle to apply your sealer on your grout. Follow the instructions on the product label for the best results. Make sure you cover all the grout lines evenly and avoid getting any sealer on the tiles. Wipe off any excess sealer with a cloth or a paper towel.
  • Let it dry. Depending on the type of sealer you use, you may need to wait for several hours or days before you can use your tiled surface again. Check the product label for the recommended drying time and follow it carefully. Avoid walking on or touching the sealed area until it is fully cured.

How to Get Professional Help

Grout sealing may seem like an easy DIY project, but it can also be time-consuming, messy, and tricky. If you don't have the right tools, skills, or experience, you may end up with poor results or even damage your tiles or grout.
