What are Ceramic Tile Floors?

Before getting into the main gist, let’s examine what exactly are these types of floorings.

Funny enough, ceramic has been around for centuries, although not necessarily used as tile floors. Cultures all around the world valued ceramics for their delicate shine, smooth texture, and elegant look.

It was used in various decorations like for making dolls and fine China. In recent times, ceramics has transcended beyond its use for decorations, and it’s now a popular material for residential flooring all over America. 

Ceramic tiles are made from clay. When clay is exposed to searing hot temperatures (around 2,300 to 2,400 degrees Fahrenheit), the finished product is ceramic tiles.

Ceramic tile comes in a variety of colors, sizes, and designs. There are so many interesting designs that are created with ceramic tile that can easily suit any space.

Due to its durable nature, ceramic tile may be used in all types of spaces. However, it is often used in kitchens, bathrooms, foyers, mudrooms, and other high-traffic areas.

Does Ceramic Tile Need to Be Sealed?

Most often, the only floor types that need to be sealed are hardwood floors. Most ceramic tiles have a glass glaze on the top of the clay back, which provides a non-porous surface as the glass will not let anything penetrate it unless it is unglazed.

Most floors are sealed to protect them from excessive moisture, which can easily damage them. This does not apply to ceramic tiles, which have a protective barrier against moisture.

As mentioned earlier, only unglazed ceramic tiles need to be sealed as the protective barrier is absent in this type of ceramic tile. It is worthy to note that most home improvement stores have glazed ceramic tiles, which require no sealing.

Why you Shouldn’t Seal Ceramic Tiles

Are you bent on sealing your ceramic tiles? Then maybe it’s time for some reevaluation. Below, we will highlight reasons why you shouldn’t seal your ceramic tiles.

1. Sealing Your Ceramic Tiles Might Make Cleaning More Difficult.

There is a misconception that sealing your ceramic tiles will make cleaning easier; this is not true. Going by the nature of ceramic tiles, we know that it is easy to clean and maintain. The problem might be that you have not gotten the perfect cleanser for your floor.

3. Sealing Ceramic Tiles Will Make the Floor Surface Slippery

While this problem might be averted if you use a non-slip sealer, we do not recommend sealing ceramic floor tiles. Even when a non-slip floor sealer is used, you will need to reapply the sealers regularly, ultimately creating a new cleaning problem.

4. Sealing Ceramic Tiles Make Maintenance Difficult

A sealed ceramic floor tile is just too much work. Most floor sealers are softer and will be affected by traffic, spills, and day-to-day wear and tear. Invariably, this spells more work for you. You will have to spend more on repairing and replacing the tiles.
