When it comes to natural stone worktops and other products, there have been cases where marble was sold as granite. Misidentifying the type of stone means that the end user will have certain expectations that will not necessarily be fulfilled. These two stones might look somewhat similar at a glance but they are vastly different when it comes to their porosity and acid sensitivity.
Acid sensitivity and porosity
Acidic substances like lemon juice react with the calcium carbonate found in marble. This results in etch damage. There are varying degrees of etching that can occur. The more severe the damage, the rougher the affected surface will feel. Granite, however, is not as sensitive to acidic substance. While you should still always clean up spills right away, these worktops will not prove as prone to etching. As for porosity, marble is not usually as porous as granite. Granite, therefore, will absorb moisture more easily. Not to worry, however, for every potential problem, there is always a solution.
Stain and etching prevention
When it comes to stain prevention, the first rule is to wipe up spills immediately. Secondly, you should have your worktops sealed. Test your seal by spraying a small amount of water onto the surface. If water beads form, your seal is working well. If not, you should have your worktops resealed. To prevent etching, make sure that you always use a cutting board, clean up spills quickly and use a stone safe cleaner.
If your worktops become damaged despite your best efforts, don’t lose hope. Repairs are possible and, if the damage is minimal, you might even be able to perform the touch up yourself. Ask your natural stone expert for their recommendations regarding a suitable compound to help buff out etch marks. If the etching or damage is too extensive, you can always call a professional.
Knowing exactly what type of stone you have installed in your home is important when it comes to stone care. Make sure that you ask your supplier any and all questions you need to set your mind at ease before a new stone worktop installation.
