The 10 Best Sealers for Ceramic and Porcelain Tiles

One might think that ceramic and porcelain tiles are impervious to staining and water damage since they are such solid building materials. Some tiles are more porous than others, meaning that they have tiny channels through them which can allow liquids or small dirt particles to pass through below the surface.

Tiles and stone are so strong and durable that it might surprise you later down the line when a spill stains your expensive flooring, or you get a build-up of rust and hard water stains that becomes a nightmare to remove. And of course, you shouldn’t forget to look after the grouting between tiles which easily retains water and becomes a breeding ground for mold!

Before your grout becomes brittle and stone or tiled surfaces are stained and need replacing, consider using a sealant that is applied and dries fast to create a protective barrier against moisture and stains. This will save in future costs from replacing materials, and the labor and time which that involves.

Not only do these products prevent liquids from soaking into the tiles and grouting, but the protective coating for some sealants also enhances the natural color of stone or tiles in the process.

Should You Seal Ceramic and Porcelain Tile?

Ceramic and porcelain tiles come either glazed or unglazed, and unglazed tiles will easily soak in water or oil so they will need protection from a sealant. Glazed tiles are only somewhat porous and don’t always need to be sealed depending on the environment they’re used in, but in situations where they will be exposed to moisture regularly such as in your bathroom, kitchen, or patio, it’s a smart idea to seal them.

A sealant protects the tiled surface from dirt and staining over time – essentially futureproofing them.

Another important factor to keep in mind is that often the grout which holds the tiles tightly in place is unprotected. If that grout isn’t sealed then you can expect it to deteriorate much sooner, staining, breaking apart, and becoming a breeding ground for mold. Cleaning old dirty unsealed grout is difficult and requires a lot of elbow grease, the use of harsh chemicals, and abrasive cleaning supplies which could all damage the tiles in the process.

Compare that to cleaning sealed grout which will be relatively easy using soapy water and a sponge, and you’ll be thanking your past self for going through this process now!

What to Consider When Buying a Tile Sealer? 

Easy Application

You’ll see some products that come in spray bottles, some that need to be mixed before application, and most that arrive in a bottle ready for application after a good shake. In the description for each sealant you’ll find instructions for application, so do make sure that you have all the necessary tools to apply your tile sealer of choice when you purchase it.

How Well it Seals the Tile

What you want is a product that prevents liquids from easily penetrating the surface so you have time to clean spills before staining can happen, while adhering perfectly to the surface of the tiles and grout. A good sealant makes cleaning a breeze and extends the life of your tiles, stone, and grout.

How Long it Will Last (Durability)

The more time before reapplication is necessary, the better, since you’ll be saving money and effort if the sealant has a longer working life. Take note that most of these products aren’t formulated to endure the elements outdoors, and if it’s used outside most manufacturers will warn that the expected working life of the product will be reduced.

Anti-Slip Design

Especially for floor tiles in a bathroom or kitchen, be aware that if the sealant leaves the tiles slippery then they will become a safety hazard. Take caution and look for specifications that clarify if the sealant is designed to give grip to sealed tiles or leave the texture of the tiles as is – which is the case for penetrative sealers. Failing that, see what other users have to say about their experiences in the reviews.

Safety Precautions

Liquid tile sealants are not made for contact with skin or eyes and can harm you and your pets if you aren’t careful with it before it’s dry. Always comply with manufacturer’s instructions for safe application, use disposable gloves while handling these products, ensure that the area is well ventilated, and always keep out of reach of children and pets.

See on Amazon

Stone Grip non-slip floor treatment solves the problem of slippery surfaces differently from the other products on this list.

There are mixed reviews since some tiles haven’t reacted well to this product so as always, try it out on a test piece to see if you’re happy with the results before using it to improve grip on the entire bathroom floor. And remember, this product won’t help with sealing the tiles or grout against water damage or staining but can be used in conjunction with a penetrative sealer applied after the non-slip floor treatment.
