MARBLES AND GRANITES: Natural marbles and granites may differ in colour to the samples, with slightly or quite pronounced small holes and grains. Marbles and granites tend to absorb liquids due to their microscopic porosity and then release them through evaporation. This feature exposes them to the risk of absorbing substances that might stain them irreparably (varnishes, cosmetics, perfumes and other substances). Adequate and continuous maintenance, without excessive use of unsuitable soaps or detergents, retains the brightness of marble. MARBLE/RESIN: Marble mainly comprises calcium carbonate, therefore it is subject to chemical attack from acids: the products indicated do not contain aggressive substances. Not only do they ensure excellent protection for tops, but they also allow maintenance that retains the shine of colours and the natural beauty of this stone. Products based on fine-grained marble and homogenous colours are particularly delicate. QUARTZ/RESIN: In this case, the mineral content is not subject to chemical attack from acids. Consequently, the products indicated must only include ones that do not have a high alkaline content (basic pH), which might alter the bonding resin, particularly in terms of aesthetic appeal. Use and maintenance: The best way to prevent stains is to remove soiling promptly with a damp cloth or mild detergents, before hardening of the same. This is especially important for fine grained marble, particularly sensitive. The damp cloth is a simple solution of daily use and can be used in every case, where the action of the agent has not damaged the surface of the material. We recommend the use of neutral detergent.
