Cleaning and treatment for outdoor cotto from installation to maintenance: 5 things to know

It's easy to talk about cotto cleaning and treatment, but this material requires specific care depending on its "life cycle", let's discover them all!

Cotto is one of the most popular and chosen outdoor materials for setting up and decorating both external and internal areas of the home.
But not everyone knows that cotto, despite its resistance, is a very delicate material and needs special attention during all its “life” phases.
Don’t forget, in fact, that cotto is a compound made of clay and water and that, if on the one hand gives it resistance, on the other it makes it a vulnerable material that holds liquids and dirt much more easily than ceramic surfaces.
If we imagined an illustrative table on the strengths and weaknesses of cotto, porosity would gain the first position among the weak points.
From the moment of laying, passing from that of cleaning, to arriving at extraordinary maintenance, cotto requires specific treatments that today we have decided to summarize and illustrate in 5 useful tips, let’s start.

1. OMG, post-laying cleaning!

Everyone, sooner or later in life have to face with the cleaning of the house after construction work and, only after, it’s possible to find out how hard it is.
Cotto floors are certainly not exempt from this type of intervention. The cleaning of outdoor cotto floors after works requires particular attention and, to remove efflorescence and cement residues, certainly a lot of energy.
But in order not to make mistakes and try to do as little effort as possible we can follow simple steps. Let’s find out together.

After a construction site, the first thing to do is: wait.
Yes, you got it right, after laying it is absolutely essential to spend time, let the material breathe and make sure that the surface “dries very well”.

Once perfectly dry, to effectively eliminate all the residues, we recommend a cotto treatment consisting of: VIACEM a detergent for descaling washing of cotto, terracotta, klinker, antique pebbles and all materials resistant to strong acids.
We recommend, before applying it over the entire surface, to make a small test on material to check the resistance of the product. Once the resistance has been verified, spread it on the floor, either pure or diluted according to the type of dirt to be removed, and rub vigorously with BROWN PADS. In the end, it is necessary to rinse with plenty of water.


2. Is it important to clean the outdoor cotto every day?

To maintain the beautiful and bright cotto over time, “daily” cleaning is certainly essential!
And if we talk about outdoor cotto, we certainly need more care.
The outdoor cotto is in fact subject to a more obstinate and difficult to eliminate dirt than the indoor one.
To face this type of dirt we recommend first of all to sweep the surface with a broom every day, doing so we will avoid the fouling of vegetable substances such as leaves and natural residues which, if left to macerate, will tend to create resistant patinas.
In addition to sweeping the flooring, remember that cleaning external cotto floors must be carried out regularly, always taking care to use dedicated products.

To wash the cotto we can try to make a DIY detergent by mixing 2 liters of water, half a glass of white vinegar and flakes of neutral vegetable soap.
Or, to have beautiful cotto floors, we can more easily use a very delicate specific product such as UNIPUL: a concentrated detergent for multi-purpose use, suitable for intensive degreasing cleaning on all hard surfaces. Characterized by a low foaming, it does not leave halos and guarantees a pleasant fragrance in the rooms.


3. External cotto: how can we fight humidity?

Moisture is one of the main enemies of outdoor cotto!
If you often look at your terrace wondering what is the cause of those annoying white spots on the cotto, you are in the right place to find out the answer. The white spots are generated precisely by humidity.
Winning the battle against humidity, however, is not at all simple, so starting early and speeding up with an anti-humidity treatment on cotto seems to be the ideal solution to counteract its appearance.

To perform a treatment on anti-humidity and anti-stain cotto we recommend a truly effective product such as: TIM, an impregnator that forms a water-repellent barrier avoiding and strongly counteracting the rising damp and the penetration of liquids on all porous materials. Easy to apply, to perform this treatment on cotto just follow simple steps and have:
– one sponge;
– a fleece spreader;
– a microfiber cloth.
Once the surface has been wetted evenly and completely with the product, it will be enough to wait for the perfect absorption of the material (usually from 4 to 8 hours) and you’re done!


4. Maintain cotto over the long term

Like all surfaces, objects, materials, more care you give to them and more they will enjoy a long and brilliant life. So, in addition to ordinary cleaning, let’s remember to periodically perform specific types of treatment on these types of materials, such as an anti-fouling treatment with PAV05: a product in resinous-wax emulsion resistant to atmospheric agents for the finishing of cotto. A treatment for cotto, that prevents and fights the appearance of all types of harmful plants such as algae and mosses. Over time, they tend to spoil and above all to stain the cotto.

5. Cleaning is ok, but how to make a cotto floor shine?

It’s easy that over time our outdoor cotto floor will lose its original brilliance.
But don’t worry because there are natural methods that will help us make our floors shine again.
First of all, to make our cotto shine, it will be necessary to spread linseed oil over the entire surface and let it absorb completely. Once dry, the next day, repeat the same action. After another 24 hours, wet the surface with beeswax, let it dry and repeat the operation at least a couple of times a year.

Following these 5 cleaning and maintenance tips, our terracotta floors will remain fascinating and shine for a long, long time!
