The main argument for selecting an engineered stone as a countertop instead of a granite countertop is that the granite is more vulnerable to stains and have a high absorption. Is this really true?
Testing our materials
Lundhs´ granites have all been tested both with European Standards (EN) and International Standards (ASTM) to prove that the absorption is very low. This easily explained by weighing a piece of the stone you are testing, then lowering into a water-basin for a specified time and then weighing it after it has been soaked in the water. The change in weight will indicate how much the material absorbs. The outcome for Lundhs materials is in the range 0.04% to 0.26% as the highest.
A little experiment
Does this mean that Lundhs materials will get stains from food or liquids normally used on a countertop? To verify this, we made a practical test by putting the most common ‘stainers’ such as tea/coffee, red wine, olive oil and a slice of lemon, on our materials on a Friday afternoon. Then we wiped it clean 65 hours later when we came back to the office. As you can see from the photos, none of the materials actually showed any stains after this test. The samples were all just polished without any form for sealant or resin.
It means that you do not have to worry about stains if you choose one of Lundhs materials as your granite countertop.
