“Should we seal a porcelain tile after installation?” is a question that is currently flooding the tiles industry. There are a lot of conflicting views on this topic; some say yes, some say no. But, what is the accurate answer?

To fully understand the answer, we will have to dig in a bit about the history of porcelain tiles. In this post, we are going to explain how a porcelain tile differs from others, and should you seal it or not. Keep Reading!

What Is a Porcelain Tile?

Porcelain tiles are one of the most versatile and durable tiles with incredible stain-resistant properties. They originally came from Italy, and slowly started rocking in the whole world due to their high quality.

Moreover, these tiles contain high silica content, chemical and wear-resistant properties, and maximum thickness. Also, the most notable feature of these tiles is their wonderful water absorption capability. No matter how much water, they can bear and absorb it all.

Types of Porcelain Tiles

Nowadays, porcelain tiles come in various and different forms; each with different prices, performance, and functionality. Some have a lower water absorption rate, and some have a higher. So, whether you should seal them with a sealer or not depends on the quality of your tiles.

Additionally, porcelain tiles have further two types:

  1. Polished Porcelain Tiles – The ones with a glazed finish.
  2. Unpolished Porcelain Tiles – The ones with a matte finish.

Both are almost the same, with near to zero differences between them. The only dissimilarity between them is their finish, nothing else!

So, Should You Seal Your Porcelain Tiles?

Now moving on to the main question – The answer totally depends on what types of porcelain tile you are opting for. Also, most tiles are already sealed during the manufacturing process, so you need to look out for that too!

  • For example, if you have polished porcelain tiles, they will require some sealing. This is because they have a glazed finish on the top surface that can get ruined after rough use or intense wear and tear.

Still, if you are unsure, you can always perform a simple test. Take a spare tile and put a line on it with a black pen or permanent marker. Then, take some spirit and try to wipe off the mark. If the mark disappears, your tiles are already sealed. If not, then it would be best to seal them with a good quality sealer!

  • Similarly, if you are opting for unpolished porcelain tiles, there are chances you might never have to seal them. However, they usually have rough textures. So, there are high chances they will trap residue and dirt particles inside.

For this, we would recommend sealing or cover your unpolished porcelain tiles with a porcelain protector. A protector will act as a barrier between the tile and dust particles while protecting from stains and tear. The best part, you won’t notice any difference in the appearance of your tile after using a protector.

What Sealers Should You Use?

The composition of porcelain is very unique. Therefore, just “any” product won’t work. We would recommend you use these two types of sealers only for your porcelain tiles:


Impregnators or penetrating type products are applied below the surface of the tiles. These products are entirely safe, give a natural look to your tiles, and work best for porcelain!

Floor Finishes

Floor finishes also act as an active and efficient porcelain tiles sealer. Apart from protecting your tiles, floor finishes also give your tiles a shiny and glossy look.

Wrapping Up

The answer to “should I seal my porcelain tiles?” is no longer a NO! Yes, we know that porcelain tiles are one of the most durable and strongest of them. But, what is wrong with being extra cautious? With a little extra effort, you will be able to preserve the beauty and durability of your tiles for years.
