Porto is famous for its quaint old town, which has been declared a World Heritage Site by UNESCO. Here you can admire the charming cobbled streets, the colorful facades of the buildings and the traditional restaurants that serve the famous Port wine.

In addition to its architectural heritage, Porto is also renowned for its beautiful bridges that cross the Douro River. The Dom Luís I Bridge, designed by Gustave Eiffel (famous for the Eiffel Tower in Paris), offers a breathtaking panoramic view of the city.

Visitors to Porto cannot miss the opportunity to explore the many wineries in the region. Here you can discover the process of producing Port wine and taste some of the best wines of the area.

Finally, Porto also offers beautiful beaches along the Atlantic coast. The beaches of Matosinhos and Foz do Douro are ideal for relaxing in the sun or taking a walk along the coast.


What is cotto

Cotto is a very ancient and versatile building material, also known as “terracotta” or simply “brick”. It is a type of tile made by firing clay in high temperature ovens. The firing process gives the cotto a remarkable hardness, resistance and durability, making it ideal for a wide range of applications and building uses.

One of the most distinctive features of cotto is its red or terracotta color, which derives from the presence of iron minerals in clay. This natural color is often appreciated for its warm and cozy aesthetic, and is used to cover walls, floors and roofs.

In addition to its beauty and resistance, cotto is also an environmentally friendly material, as is made from natural raw materials and can be recycled. It is known for its ability to maintain a constant temperature inside buildings, contributing to thermal and energy insulation. In addition, cotto is often used in restoration and conservation projects, as it allows to preserve the original appearance of historic buildings.

This type of flooring is very popular in Portugal and is used both indoors and outdoors. Thanks to its weather resistance, Portuguese cotto is ideal for use in external environments such as patios, terraces and gardens.


The Wet Effect Treatment: Sustainable Innovation

The wet effect cotto is a particular finish that is applied to the cotto floor to give it a shiny look similar to that of the just poured water. This treatment is used to enhance the natural beauty of the material, creating an elegant and modern aesthetic effect.

The wet effect treatment used by Jorge Almeida is carried out exclusively using water products, thus avoiding the use of dangerous solvents and the unpleasant smell often associated with similar work.The undisputed protagonist of this treatment is TON PLUS, a water-based product that is able to tone the cotto materials in a similar way to traditional oil-solvent-based impregnations, but with a much lower environmental impact.


How to treat spoiled cotto

Let’s see then what were the products to clean the Portuguese internal cotto.

The intervention began with a descaling cleaning phase.

To remove incrustations, cement grouts, paints and dirt from the surface of the cotto, a single brush is used with a brown disc together with the descaling product VIACEM, a strong buffered acid detergent specific for removing cement grouts, efflorescence and limestone encrustations on cotto and terracotta.

This step is essential to prepare the surface and ensure the adhesion of the subsequent treatment.

The heart of the process is the application of TON PLUS, an odourless water product that gives the wet effect to the cotto. This protective hydro-oleophobic product specific for stone materials with high absorption (cotto, stones, terrazzo…) offers a lasting protection against rising humidity and serves to remove stains on cotto, giving the material a luxurious and bright aspect.

After the application of two coats of TON PLUS and the drying, two more coats of the anti-wear and anti-dirt finishing IDROFIN MATT are applied, which protects over time the base treatment of the material and its initial aesthetic characteristics, as specified in the data sheet.

The art of craftsmanship in Porto, masterfully represented by Jorge Almeida and his company, shows us that tradition and innovation can coexist. The wet effect treatment, made with eco-friendly Marbec water-based products, represents a step forward in environmental sustainability without compromising the beauty and durability of Portuguese artisanal cotto. Thanks to professionals like Jorge Almeida, Porto continues to be a beacon of art and innovation in the world of craftsmanship.
