Do large format porcelain tiles require sealing?
Does porcelain need to be sealed? This is often a key consideration for designers and architects who are putting together design schemes that include the installation of large slabs. After all, the right application will ensure longevity and increase the value of a home or even a business.
In this article, we’ll explore why materials like cement and terracotta require regular sealing, and how Atlas Plan slabs, in contrast, deliver maximum performance without this need.

Understanding the core need for sealing large format tiles
The sealing of tiles might seem like a natural choice when you are working on design projects. In some cases, you will certainly be correct. For instance, materials such as cement and high-use surfaces might need extra protection – something that sealing can certainly provide. However, for a material like porcelain stoneware, it’s not necessary to consider this step: in fact, its non-porous surface already makes it waterproof and stain-resistant.

Material porosity: the deciding factor in tile sealing
Some materials, such as natural stone, cement and terracotta are more susceptible to absorbing moisture, which could cause damage over time as well as bacterial growth. Highly porous materials should ideally be sealed, as this will provide better protection and limit water damage especially if these design elements are used in bathrooms and kitchens.
Why Atlas Plan porcelain slabs do not need to be sealed
Thanks to their almost zero porosity, Atlas Plan's large format porcelain tiles don't require sealing. They are waterproof and offer excellent stain resistance.
Do large format porcelain tiles need to be sealed?
