Are you looking for the best grout sealer that would be ideal for your brand new tiles in the bathroom? Or are you just interested in the perfect moisture and dirt protection for the plaster on your ceramic kitchen floor?
It doesn’t matter what type of tiles we are talking about. The dilemma is always the same. Which grout sealer would be the best choice? Well, answering this question isn’t an easy task. I know from personal experience how tricky that can be. The biggest problem is that we don’t have any objective and established standards that we could use as a metric. And you can forget about the manufacturers and their claims – they are really not the source you should rely on. Of course they’ll claim they make the best product ever, but that doesn’t mean it’s a perfect option for you.
In case you don’t have the time to read through all this, then jump here to see the best options available! You can thank me later 🙂
Basically, when sealing grout, this is the final result you want to get:
And there is only one way to find the best grout sealer. It’s personal testing! I know, I know. You probably think it is impossible for you to check every applicator and every spray on the market. I understand you. You’re not so crazy about grout sealing to do something like that. But I am. Yes, I tested almost all products I could find around during my contractor career. This article is the result of this research.
However, before I jump on with the list, I just want to say a couple of things. If you are looking for a product that would be ideal for all kinds of tiles and grouts, that would be ideal for all joint sizes, durable and easily removable in the same time, both chemical-free and penetrating, you wouldn’t find such a product. This is the reason why you should ask yourself what would be the perfect sealer for the certain job, not the perfect in general.
For instance, if you already sealed your tiles, you wouldn’t need the sealer again. It is the same with the epoxy grout. What about non-glazed tiles? Just don’t dare to apply it on these tiles. If you do, your piece of work will be ruined for good. In addition, for long- lasting protection, so – called surface sealants or coatings would not be enough. Bathroom tiles need silicone, not water based products. You see? The decision what sealant would be the best depends on several different factors, such as the type of the tiles, location, your intention, applying method, budget…
Ok, now after we have discussed all that, I also want to say something about different grout sealers. These products are divided into three major groups, which all have their own subcategories. I will list only the products from the two groups – surface and penetrating sealants, because the third category, color tile protectors, is something that nobody can rank. It is all about personal preferences.
Surface sealers are also known as membrane forming or just coatings, simply because these products stay on the surface of the tiles or grout and make the protection barrier from the water, moisture, oil and other dirt. As we already said, we have more subcategories here, and the main difference between them is in the substance of which they are made. In that way, you can choose between water, silicone or even acrylic sealants. They all have their pros and cons, of course. However, you should know that these products are not very durable as the products from the second group. According to my experience, water and silicone based products can withstand from three to five years. On the other hand, acrylic can be intact for about 10 years.
Regarding penetrating sealers – this group also has several subcategories. In general, we can divide them into two types: oleophobic and hydrophobic. These types are more durable than coatings, but they are a little bit harder for applying at the same time. If you want long-lasting results, you should definitely use this kind of sealers.
Few Grout Sealant Options
Miracle Sealants 511 is a premium penetrating sealer that you can use both for interior and exterior tiles. This product penetrates deep in the tiles, making the invisible barrier for the water and oil stains. At the same time, it allows the vapor to escape. You don’t have to be worried about your ceramics, because this protector wouldn’t change its natural look. This product is well- known because of its special molecular structure, which makes this sealer more water resistant than similar products. I would definitely recommend any other product from the line of Miracle Sealants as these are quality made products.
Aqua Mix Sealers Choice Gold is another supreme water based impregnator sealer that is very durable. I used it many times and I must admit that all grouts and tiles look great even after a couple years. The optimal protection is reached only after four hours. The great thing about Aqua Mix is that you can use is it in the kitchen or food preparation rooms without any fear of intoxication. It is effective as both grout sealing and pre-grouting sealer.
DuPont StoneTech BulletProof is another water based penetrating sealant that showed very good any time I tried it. It is especially great for natural stones and porous tiles. You can use it equally outside an inside. Although it lasts shorter than other products from the list, you can be sure that your tiles or stones would be perfectly safe at least five years.
Scotchgard Tile and Grout Multi-Surface Sealer is definitely one of the best water based surface sealers on the market. It is very durable and you will be pleased with the condition of your tiles for a long time. It is very important that you can apply it even on the extremely porous tiles, same as on the natural stones, concrete and grouts. This product provides great protection from a wide range of strains. This grout sealer is applied in one coat with brush, roller or spray.
