Natural stones are somewhat porous by nature, meaning that they have the propensity to absorb liquids which may lead to staining or discoloration if not properly sealed and maintained. With granite and quartzite, you almost have no risk of staining, but marble surfaces will need caution. To avoid anything at the highest level, before we install your granite or marble countertop, the last step we take at our premises is to install a liquid sealant that is absorbed into your countertop to provide a barrier against liquid absorption.
Depending on how heavily your countertops are used and which products are used to maintain them, this sealant can either be washed out or enhanced. Frequent use of common household cleaners will tend to wash out the sealant. If you notice that liquids are being easily absorbed into your countertop, wipe them off immediately and and apply a new coat of sealant. It is a very easy process which you can easily do it yourself at home. We will be happy to assist you on that if you have questions.
Granites differ in their texture but they all have similar properties such as their resistance to the invasive action of most substances found in the house. Unlike marble and limestone, granite and quartzite are the least affected by acids or alcohol. It shouldn’t be damaged from standing hot utensils on it or by sharp knives.
All stones, due to their granular construction, are porous to a greater or lesser extent and most granites fall into the latter category. Beetroot, wine and cooking oil, particularly when hot may cause a stain on your marble or granite (very low chance) work top, and you should always clean this up immediately with kitchen roll.
To reduce the ability of any natural stone to absorb liquids, we treat the surface with a proprietary sealer that penetrates the surface and fills the microscopic voids between the crystals. This process is first done in the factory at the completion of manufacture and again before installation.
Marble and Limestone are susceptible to the aggressive action of acids and alcohol. Care should be taken to remove spillages of fruit juice, particularly lemon, wine and vinegar, beetroot etc. E.g. The residue of red wine on the base of wineglasses will leave its mark. Nail varnish and any other solvent or oil based products will stain if not wiped up immediately.
