But before I tell you what treatment was done, let’s see why it forms the patina of algae on tuscan terracotta floor.

Perch on terracotta form the mosses and lichens?

Terracotta or Florentine cotto, a material of natural origin. Its use dates back to Etruscan times. Then as now, it originates from the clays senesi which, when cooked, they turn into tiles, bricks and tiles. For a porous material, terracotta tends to absorb and retain moisture. In this way, it becomes an ideal substrate for plant: these are microorganisms that attach themselves to the surface and form the ugly dark patina we saw. The phenomenon so severe as pi pi the area in shadow, as in this deck. How to get rid of these stains on terracotta plant outdoors? There are two methods: one short-term and one long-term. Let’s go through them one by.

Clean floors terracotta exterior: the quick method

The fast method for cleaning of cotto fiorentino (or Tan) outer washer. But, as we have already shown in a different article, this mechanical method not effective. true that the cleaner removes the layer of algae and mosses. However it does not eliminate the problem: after some time the patina is riformer. There is an effective method to clean the external pi cooked. A method used by professionals. This is a non-invasive solution and, above all, in the long term. You have to run an anti-fouling treatment and for cooked outside. A solution by professionals: we see the treatment performed by Wilson.

Treatment for terracotta exterior: and the tiled floor as good as new!

A long-term solution to the problem of the MOSS exist. The firm Wilson was called to perform a double treat. First it was necessary to remove the patina of organic material that covered the surface. Secondly you are fought water infiltration. The cooked, especially if external, must be protected from moisture to prevent holding the moisture. Finally it was necessary to apply a protective for cotto. The preservative has the function of sealing the pores of the material. In this way we obtain 3 results: mosses will not grow, it will be easy to clean and stain resister.
