New cement coating turns walls into magnetic surfaces

The construction industry has been quite reluctant to introduce truly innovative materials in the last few decades. Traditional concrete continues to be the undisputed king of construction sites, with humanity using as much as 30 billion tons of it annually. Despite its undeniable strength and affordable price, working with it often brings with it a lot of problems. Each time you install shelves, hangers or pictures, you often need to use drilling machines, and the resulting holes need to be patched and repaired when moving or reorganizing a space.

In response to these everyday "confusions", twenty-nine-year-old Argentine Marco Agustín Secchi has developed a solution called Ironplac. It is a special formula of cement mixture to which selected mineral and iron fillers have been added. This specific composition allows the coated walls to easily attract magnetic objects, and the final product looks completely indistinguishable from a completely normal, classic concrete surface.

The theoretical utility of such a concept is extremely attractive, as walls in homes, offices, workshops and classrooms could be redecorated in an instant and without permanent damage. However, it is crucial to note an important detail. The surface treated with Ironplac material does not emit a magnetic field by itself and will not attract random metal objects. The wall only becomes active when in contact with objects that already have their own magnets built in.

Despite the great enthusiasm on social media, the product is still only in the prototype phase. Before the material can even seriously enter the demanding construction market, experts will have to answer a number of open practical questions. It is currently not known how much weight such a wall can withstand in the long term. It also remains unknown how the coating behaves in a humid environment, how it is affected by repeated application of new layers of wall paint, and how durable it is when heavy objects are constantly moved. Only the answers to these dilemmas will show whether this is a practical revolution or just a fleeting technological peculiarity.
