In a villa located in the Tuscan countryside, a restoration was carried out on an outdoor terracotta floor, which had deteriorated due to mould, lichens, moss, and black stains caused by moisture. The main goal was to effectively remove mould and lichens and protect the material over time.

During the cleaning phase, the team used ALGANET®—a professional stain remover specifically formulated to eliminate biological colonies from terracotta and stone surfaces. The treatment successfully removed even the most stubborn encrustations without damaging the material.

Afterwards, they applied TIM®—a transparent and breathable protective product designed to prevent the future formation of mould, stains, and new lichens. This product has the advantage of preserving the aesthetic appearance of terracotta while maintaining its breathability.
The final result is a fully restored terracotta surface: clean, protected, easy to maintain, and resistant to atmospheric agents. This intervention stands as a concrete example of how to remove mould and lichens in a long-lasting and professional way, thanks to Marbec products.

If you’re wondering how to clean blackened outdoor walls or how to remove green stains from outdoor walls, you’re not alone. Garden walls, coping stones and handrails affected by algae and lichens can quickly spoil the appearance of your property, making it look less cared for even when everything else is in perfect condition.

Mold on outdoor floors, green algae, moss and lichen can quickly make patios, walkways, terraces and driveways look neglected. In addition, these biological deposits often create slippery surfaces and dark stains that are difficult to remove with ordinary cleaning. In this practical guide, you will discover how to remove mold from outdoor floors, eliminate algae and lichen effectively, and restore the original appearance of stone, terracotta and concrete surfaces with long-lasting results.
