At Ovaeda, we frequently encounter the question: is marble more porous than porcelain? The answer is yes, and this distinction significantly impacts the choice of materials for outdoor decking and accessories.

Marble's natural porosity makes it more susceptible to staining and requires more maintenance, whereas porcelain's dense, non-porous nature offers durability and ease of care.

In this article, we will explore these differences in detail, providing the information you need to make an informed decision for your outdoor spaces.

Is Marble More Porous Than Porcelain?

Yes, marble is more porous than porcelain. This is the case when comparing any natural stone and porcelain. But let's unpack that a bit. Marble, a natural stone, has tiny pores and capillaries throughout its structure.

These pores can absorb liquids, making marble susceptible to staining and etching, especially from acidic substances like lemon juice or wine.

Porcelain, on the other hand, is a man-made material that is fired at extremely high temperatures, resulting in a very dense and non-porous surface.

Understanding Marble's Porosity

Marble is a stone that has been used for centuries. Its natural veining and unique patterns make it a favourite for high-end projects. However, its porosity means it requires regular sealing to prevent stains and damage.

According to our research, unsealed marble can easily absorb water and other liquids, leading to potential issues in outdoor environments where it's exposed to rain and humidity.

Porcelain's Superior Density

Porcelain is engineered to be non-porous and highly durable. This makes it an excellent choice for both indoor and outdoor use, and its longevity makes porcelain sustainability high.

After putting them to the test, we've found that porcelain tiles do not require sealing and are resistant to stains, making them incredibly low-maintenance. This is to do with what is porcelain tile made of, as well as the high firing temperature during the manufacturing process ensures that porcelain is much harder and denser than marble.

Maintenance Matters

One of the biggest advantages of porcelain over marble is maintenance. From our experience, marble surfaces need to be sealed at least once a year, and you must be cautious with cleaning products to avoid damaging the stone.

Porcelain, being non-porous, only needs regular cleaning with a mild detergent. This makes it a more practical choice for busy homeowners who want a beautiful space without the hassle of constant upkeep.

Cost Considerations

Cost is always a factor in any home improvement project. Marble can be significantly more expensive than porcelain, not only in terms of initial purchase but also in maintenance costs.

From our years of experience in the field, we've found that porcelain provides a cost-effective alternative that doesn't sacrifice aesthetics.

Why We Recommend Porcelain

At Ovaeda, we've worked with countless homeowners to create stunning outdoor spaces. Based on our extensive experience, we highly recommend porcelain over marble for outdoor applications.

Its non-porous nature, ease of maintenance, and cost-effectiveness make it the superior choice. Plus, the advancements in design mean you can achieve virtually any look you desire, including that of natural marble.

And, if you're wondering is porcelain paving slippery, then you don't need to worry - outdoor porcelain has an R11 slip resistance rating, making it optimal for outdoor use.


Marble is indeed more porous than porcelain, which affects their suitability for different applications. While marble offers a luxurious and timeless aesthetic, its porosity means it requires regular maintenance and care, making it less practical for outdoor use.

Porcelain, with its non-porous, durable, and low-maintenance properties, emerges as the superior choice for outdoor spaces. It not only mimics the elegant look of marble but also provides better value and ease of care.

For these reasons, we recommend choosing porcelain for your outdoor projects. Explore our range of high-quality porcelain products at Ovaeda to create your perfect outdoor space today.
