Understanding porosity: How to select the right stone for your needs
While shopping around for the perfect natural stone for your home, you will come across a variety of colorful jargon. However, unless you have a background in stone care or maintenance, some of the terms are bound to be foreign.
For example, one of the most regular terms that you will discover is the term porosity, and it is important to understand how this could affect your choice of natural stone.
When discussing materials like stone, porosity is the ratio of pore volumes within a mineral compared to the volume as a whole. The pores are tiny holes on the surface of a membrane that allow moisture to enter and exit the object.
These pores act in a similar way to a sponge which, if left unattended and undisturbed, will slowly absorb liquids over time, including any dissolved salts or other soluble materials.
This can lead to a wide range of afflictions that could affect the integrity of your stone, compromising its aesthetics and becoming costly through repairs or replacement. Depending on your stone needs and where you hope to lay them, you will need to investigate sealing options.
By choosing an impregnating sealer like STAIN-PROOF Original, you can protect the integrity of your stones. The sealer coats the pores and makes them hydrophobic, essentially repelling water away from them.
Porosity changes depending on the type of stone you select. For example, igneous stones are volcanic materials created under extreme conditions of heat and pressure, giving them a tighter, less porous surface.
Likewise, metamorphic and sedimentary stones tend to have a higher porosity, as their creation isn’t as violent. This is why marble, limestone and travertine are more porous and require extra attention.
Taking this into consideration when selecting your stone options can help you plan ahead and ensure you undertake all the necessary steps to keep your stone looking great well into the future.
