He polished is a mechanical process that uses abrasive discs (such as diamond discs) to grind, refine and level the surface, eliminating deep scratches, eyebrows, open pores and the damaged surface layer. On the other hand, the crystallized or polished It is a chemical treatment that densifies and seals the surface (commonly in marble or terrazzo), providing a luminous shine and surface protection, but without the ability to correct a base that is already irregular or very deteriorated.

No, it is essential to first identify the material. He Nolla mosaic It is composed of vitrified ceramic tiles, very resistant and low absorption, while the hydraulic mosaic It is cement-based and is much more porous. Although both modernist floors can be polished, the cleaning processes, pressure, type of abrasive and final protection products must be adapted to the nature of each material.

It is necessary to act quickly to avoid leaks or irreversible stains. The correct steps include: assess the damage and do not step on the area, remove the broken piece with a fine chisel and a rubber hammer so as not to affect adjacent pieces, vacuum up the dust and clean the old mortar. Finally, it should preferably be replaced with an original piece that matches in tone and format, level it with fine mortar, apply sealant after drying and finish with polishing and polishing.

The polishing process closes the pores of the floated concrete, creating a surface that is more resistant to abrasion and heavy traffic. In addition, it drastically reduces the accumulation of dust, makes cleaning much easier and, thanks to its ability to reflect light, it can save on lighting in the room. At the safety level, and despite its shiny finish, it offers good slip resistance.

• Use inappropriate machinery or discs for the specific material (e.g. aggressive diamonds in Nolla).
• Start polishing without having previously cleaned and prepared the floor, embedding the dirt.
• Use inappropriate chemical products (acids in limestone or cementitious materials) that may react negatively.
• Failure to carry out adequate maintenance after polishing, causing the rapid loss of the work done.

Sanding and polishing pavements, especially those made of concrete, aggregates or materials with quartz, generates fine dust that contains Respirable Crystalline Silica (RCS), a serious health risk. At Labaietador we prevent this by using machinery equipped with powerful dust collection systems (HEPA aspiration) and working with water polished. In addition, our operators strictly use appropriate Respiratory Protective Equipment (RPE).

The budget and duration vary depending on the square meters of the space, the number of rooms, and the level of wear or deterioration of the floor. Factors such as the presence of deep stains, broken pieces that require replacement, open joints, remains of old waxes and the type of finish desired (satin, high gloss) directly influence the execution times. In an average home, the process can take between 1 and 3 days.
