Porcelanato is a type of ceramic covering characterised by its low levels of water absorption, which are close to zero per cent.
Such characteristic gives it to high mechanical resistance, making it the best product when it comes to ceramic covering.
Porcelanato is an Italian word that comes from “porcelain”: by definition, a white pasty-like ceramic which is completely glazed, commonly used in the manufacturing of plates, cups, bowls, and other objects referred as “table porcelains”.
Because this type of ceramic has very similar characteristics to the porcelains, it is known as Porcelanato.
There are basically two main groups of Porcelanato, which are:
“Glazed Porcelanato” and “Polished Porcelanato”.
“Glazed Porcelanato”, such as other conventional ceramic coverings, have a surface layer of enamel, applied according to the desired aesthetic effect of the manufacturer. Enamel is a material made by fusing and melting powdered glass, which is applied on the ceramic surface, creating a durable vitreous coating.
Besides enamel, such products may also receive other types of coating, leading to their enrichment when it comes to aesthetical features or resistance, by using different graphical solutions, dry applications, and others.
“Polished Porcelanato” is produced from grinding, pressing, and firing porcelain paste under very specific conditions that allow it to be polished in the same process used for natural stones (such as marbles and granites). This procedure allows the product to reach required low levels of water absorption (< 0.1%), high traffic resistance, and low porosity, preventing stains.
Every phase of the manufacturing of Porcelanato demands high energy consumption: grinding the paste as fine as possible, applying high pressure, firing at temperatures higher than the ones used for glazed products, and is slower conveyer speed inside the oven.
Polishing, as you can imagine, demands a lot of water and electric energy consumption.
All these characteristics are responsable for the higher price of Porcelanato when compared with other products.
Such terms refer to different manufacturing of ceramic paste.
“Dry Pressing” is the manufacturing of paste from one or two types of clay which are grind without using water, and then granulated, wet, and pressed together.
“Wet Pressing” is the manufacturing of paste normally composed of, at least, four or five types, of raw material, that are ground together with water. After grinding, the paste is dried out in a process similar to the one used for producing powdered milk or instant coffee, called Spray Dryer. The granulate resulting from the drying is finally pressed together.
Porcelanato (glazed and polished) is produced by using Wet Pressing. It demands high equipment investment and high energy consumption for grinding and drying the paste, what reflects in higher prices.
Every piece that comes from any of the manufacturing processes listed above is sent either to the glazing line (glazed tiles) or straight to the oven (polished tiles).
It is difficult to give an objective answer to this question. They are just different types of products, whose aesthetical and physical appearances are unlike and not directly comparable.
Each one of them has its positive aspects, though. We can mention that, generally, glazed products are cheaper and less resistant to stains. Manufacture and graphic solutions allow to have a final product with different appearances ( wood or stone-like tiles).
On the other hand, polished Porcelanato is generally more expensive and demands more maintenance, especially to avoid stains. Its finishing has a shiny elegance that brings sophistication.
Thus, the bottom line is: choosing glazed or polished Porcelanato is actually a personal matter.
Supergloss is the commercial name that describes the coating treatment after polishing.
It consists on applying a type of resin on the surface of each piece, sealing it and making it shiner and more resistant to stains.
We can also refer to Supergloss as Nano-technology.
Supergloss makes the products shinier and more resistant to stains.
The micropososity of polished Porcelanato and other polished natural stones may lead to staining for that accumulation of dirt and dust.
Supergloss treatment seals the pores, making them impermeable, stain resistant, and shiny.
Yes, especially the glossy ones. As every ceramic product, or even like any other type of coating –such as wood, stones, and vinyl covering – Porcelanato is subject to scratches, particularly when exposed to abrasive materials such as sand and building debris.
It is important to manipulate this product carefully and keep it as clean as possible, far from sand, debris, nails, wires and other abrasive materials that are usually used at a construction site.
Protecting the areas after laying the tiles helps avoiding scratches and other wearing sings. You can do it by using plaster, carton boards, plastics, and fabrics.
No. The low level of water absorption of these products requires special mortar with chemical additive in its formula for proper adhesion.
We always recommend using adequate mortar to AC II type tiles in indoor areas and AC III type for outdoor areas. We highly recommend using good quality mortar and following closely the manufacturer’s instructions.
A good final result comes from high quality products combined with skilled labor.
For no-rectified products, we strongly recommend a 4-mm laying joint. This is the minimum joint recommended under any circumstances.
For rectified products (the ones whose edges have been sawed after firing), we strongly recommend a 2-mm laying joint. This is the minimum joint recommended under any circumstances.
Porcelanato does not demand any especial procedure for cleaning and maintenance. Daily care by using water, house cleaning products, cloths, and brushes is enough.
Occasionally, you can also use abrasive liquid soaps, such as Cif, Radium, Vim, and others to clean impregnate dirt.
It is highly recommended to keep those areas clean and free from sand and other abrasive materials.
Besides legal warrant, DELTA ensures warrant for Porcelanato, at any moment, relating to visible defects (piece selecting problems; tonal, size, and geometrical variations) that are claimed before laying the tiles, or registered before finishing their laying.
Unseen problems must be claimed as soon as detected.
Warrant does not cover scratches and wearing signs or loss of shine due to daily use.
Every ceramic material is sensible to impacts, demanding storage, handling and transportation care.
Always follow the instructions of use, laying, and maintenance of the products.
