What this article covers:

Do You Need to Seal Porcelain Patio Tiles?

The short answer is that you don’t have to. Porcelain tiles are known for their low porosity, a result of being fired at high temperatures in the kiln. This process makes them naturally resistant to moisture and staining, reducing the need for sealants in most cases.

However, it's not a one-size-fits-all situation. The specific type of porcelain tile you chose, along with its location and usage, can influence the decision to seal.

Some types of porcelain, especially those with certain finishes or used in high-traffic areas, may benefit from the added protection of a sealant. Let's delve into the details to understand when sealing might be a good idea for your porcelain patio tiles.

Types of Porcelain Patio Tiles

Glazed Porcelain Tiles

Glazed porcelain tiles are equipped with a protective layer that shields them from water and stains, making them highly resistant to the elements.

In our experience, this built-in barrier often eliminates the need for any additional sealing, allowing them to maintain their beauty with minimal effort.

Unglazed Porcelain Tiles

Unglazed porcelain tiles present a more natural and earthy aesthetic, showcasing their material in its purest form.

However, their surface contains microscopic pores that might require sealing, particularly in areas prone to frequent spills or if you desire a more polished appearance. This extra step can help preserve their innate charm while enhancing their durability.

Textured Porcelain Tiles

Textured porcelain tiles bring a unique dimension to outdoor spaces with their slip-resistant qualities, making them a practical choice for patios.

Despite their functional advantage, these tiles can attract and hold onto dirt and stains a bit more than their smoother counterparts. Applying a sealant can simplify maintenance, ensuring your outdoor area remains inviting and well-kept.

Types of Sealers for Porcelain Patio Tiles

Grout Sealers

Even if your porcelain tiles do not require sealing, it's wise to consider sealing the grout. Grout sealers help to protect this more vulnerable component from staining and moisture, ensuring the longevity and aesthetic appeal of your patio as a whole.

Impregnating Sealers

Impregnating sealers work by penetrating the surface of the tile, offering protection while maintaining the tile's original appearance.

After putting them to the test, we’ve found that they are ideal for those who wish to preserve the natural beauty of their porcelain tiles without altering their look.

Topical Sealers

Topical sealers act as a protective layer on top of the tiles, providing a slight gloss and potentially enhancing the colour of the porcelain. It's important to note that they may require more frequent application and could impact the slip resistance of the tiles.


While porcelain patio tiles are celebrated for their durability and low maintenance, the decision to seal them depends on the type of tile and its intended use.

Glazed tiles often require no additional sealing, while unglazed and textured varieties might benefit from the added protection to enhance their longevity and ease of maintenance. 

Impregnating sealers are great for maintaining the natural look, topical sealers add a protective gloss, and don't forget the grout sealers for those crucial finishing touches.
