Now that you’ve seen some of the most recommended choices available on the market, it is time to make your pick. But this can be difficult, especially when you don’t know much about these products. That’s why we’ve organized an incredibly effective guide that will help anyone in need of some guidance when buying, and if you’re one of them, you may find the most helpful advice in the following lines…


There are three main types of sealers for grout, the penetrating sealers, the enhancing sealers, and the topical coating sealers. The penetrating types are often the ones used for fixing and maintenance of damaged surfaces. These are really effective and work practically on any surface. On the other hand, you have the enhancing sealers, which are great for maintaining the surfaces a lot shinier and much easier to clean. And the topical coatings, are mainly used to provide more gloss and transparent result to the surfaces, while providing sort of a protection as well. When you go buying one of these, just remember to consider and find out the type of sealer it is.


There are hundreds of formulas for grout sealers, always designed differently so they can provide variable results. Most formulas are water-based, while others are acrylic, yet no matter how they are initially made, they need to be non-toxic for a much safer use, and non-acidic, so they don’t harm the surfaces. In addition, the formula also tells the user how fast it can dry up, and how long it will last. The most natural products are often less durable but can dry a lot faster, yet the acrylic ones provide outstanding performances but may last a little longer to dry up. Try always to go for options that can be used on kitchens with a non-toxic formula, and that can be totally reliable nonetheless.

Ease of Use

Most grout sealers are used with a simple spraying or dripping on the surface, adding soft movements with a brush or a roller. This is always according to the rules of use of the sealer. However, some products may be so dense they don’t work for brush or roller use, while others are so liquid and smooth they don’t need any type of brushing. Whatever you choose, make sure it comes with the perfect density to be used efficiently, according to your needs.

The additional advice will also help you make the right decision:

- Consider choosing the right sealer according to your needs. If you have a granite surface and not grout, you may eventually need to choose a granite sealer and not a grout one. However, it is important to note that most sealers work in almost every type of natural stone.

- Smell is sometimes pretty important for a product, so you must choose carefully or you may even end up hating your for simply being really Make sure the product doesn’t smell bad or too strong, especially if you are allergic.

- All of these options come in different presentations, from quarks to pins, or even in little tubes, and much more. This is important because not all of them provide the same type of use and efficiency. The biggest presentations are often more durable, so choose accordingly.
