We consider concrete to be a living matter and expect it to change over time with normal wear and tear, just like leather or oiled wood.
Efflorescence, non-homogeneous surfaces, porousness, micro-fissures and mould markings are all par for the course. They are, in fact, what differentiate our products from their manufactured and synthetic counterparts. These characteristics do not affect quality or functionality.
We use a penetrating sealant for all our concrete elements, except for special projects. It offers good resistance to scratches, heat and oils. However, this type of sealant offers little protection to acidic liquids, such as lemon juice, vinegar, etc. The surfaces solicited and marked by discoloration will then be enhanced by the application of sealant and will generate a natural patina.
His touch and natural finish harmoniously complement the pieces we make with care and passion in the workshop. The natural patina that settles corresponds with the vision we have of concrete: a piece resulting from the laws of gravity and chemistry carrying in it its own confection marks that will continue its life and its transformation in your environment.
For more maintenance information about your concrete piece, please consult the maintenance sheet you received with your purchase.
Here is a little video demonstrating how to remove a discoloration by using a penetrating enhancer sealer recommended by Pur Béton. If discoloration persists, repeat the operation.
For demonstration purposes in the video, we intentionally created a discoloration by leaving vinegar under a glass for a while. Acidic liquids are what can generate the most rings or discolorations on a concrete surface sealed with a penetrating type sealant.
CAUTION, make sure that your concrete piece has been previously sealed with a penetrating enhancer sealer. Other sealer technologies may be incompatible with this method.
