Marble, limestone and travertine belongs to the family of calcite minerals and appears in its most stable form Calcium Carbonate.So this why these surfaces etch easily when it gets in contact with acidity. Look at the chemical reaction below.
When in contact with acidity, your stone surface gets reduced to water and carbon dioxide and you will find etch marks often feel rough as it has lost some parts of its composition to the reaction.
The golden question now arises, will sealing my stone kitchen benches and vanities with a stone penetrating sealer help prevent acid etching? We say NO
Stone penetrating sealers cannot prevent etch marks from happening. Kindly establish this as a fact. Then the next question is why do we need a good sealer to seal marble, limestone, granite and all stone types. Here are some of the reasons why it is crucial to seal. They are:
Nano sized molecules of the stone penetrating sealer penetrates and fill micropores and capillaries of the substrate being sealed. It remains there for a substantial amount of time leaving the surface impervious to absorption hence stain-proofing it.
2. Protects Against Absorbing Water And Oil Based Contaminants
In regards to making the surface impervious as described above, the choice of the penetrating sealer used is essential to ensure that a more complete protection is offered. Some products just protects against water based staining. A good penetrating sealer will protect from all staining liquids yet allows breathability keeping the substrate healthy at all times.
3. Eases Maintenance
When a surface is sealed well, dirt and grime will not get buried deep and will be hovering over the surface. This makes cleaning and caring for the surface so much easier as less laborious activity is required. This is also applicable to porous cementitious grout which is an integral part of stone floor and wall tiling.
Back to the topic at hand. This is what you will need to seal and protect beautiful carrara, calacatta, statuario, volakas, arabescato, turko argento, stella ivory and many many more natural stone surfaces. Below are the list of products you will need for either honed or polished surfaces.
It is important to go through this whole process every 18 - 24 months. Resealing will ensure continuous stain protection against these highly delicate surfaces. Often the surface will need to professionally re-honed or re-polished as surface wear, etch marks and minor scratches does become visible after months of usage. It might be a great idea to resurface and have it sealed by a professional just about the suggested time of 18 - 24 months.
