If you prefer, use the search field:
  • 1. Which ceramic tile has resistance to scratch?

  • Try to identify with the manufacturer a material with a satin or matte surface, with MOHS resistance equal to or greater than “7”.

    The higher the brightness of the products, the more evident the scratches on the surface of the parts.

  • 2. What is the resistance that a ceramic tile has to contact with chemicals?

  • For all ceramic tiles it should be avoided the direct contact with concentrated acids, both at work and in everyday life.

    For this, observe the resistance of the ceramic tile acquired indicated by the manufacturer (packaging/catalog/internet), following the guidance below.

    GA: Enameled product resistant to household chemicals and to swimming pool water treatment;

    GLA: Enameled product with high chemical resistance of low concentration (diluted at least 20% in water)

    UA: Non-enameled product resistant to household chemicals.

    *For specification, use and maintenance with chemicals contact the manufacturer.

    Test method for determination of resistance to chemical attack is described in Exhibit H in standard NBR 13818.

  • 3. Can any rectified material be seated with dry joint?

  • Try to identify if the manufacturer guarantees in writing, and has a settlement manual. Ceusa offers on their site and packages (each 3 boxes) a manual of full settlement.

  • 4. Can it be used a smaller joint than the specified in the packaging for non-rectified products?

  • Ceusa products present low thermal expansion mass, a feature that provides settlement with dry joint. However, in bold (non-rectified) products there is variation in size among the pieces, providing different sizes of joints in the settlement.

    The use of seating joints in sizes indicated provides satisfactory aesthetic aspect to the environment.

  • 5. Surfaces coated with paints or sealed may be coated with ceramic tile?

  • Any base to be coated with ceramic flooring (floor/wall), must be free of loose particles, dust, mudstone, paints, greases and oils, rubbers, and other. These types of finishes or dirt form a film preventing adherence and mortar anchoring on bedplate.

    Over time detachments also arise. So, for a settlement of quality finishing fully remove or create a new basis for settlement.

    In sealed environments such as slabs, a mechanical protection must be made (cement-sand layer of at least 2 cm).

    A good settlement is the total grip ceramic plate on the bedplate, so only scratch or punching the base will compromise adhesion.

  • 6. How to avoid chipped on the surface of ceramic tiles?

  • The surface of a ceramic plate is composed of glaze (glass). We suggest the protection with carpets near refrigerators, sinks and closets, for cushioning of possible downfalls of sharp objects. Remembering that the composition of the glaze on the surface is a type of glass, material of low elasticity.

    The quality of the settlement also will result in resistance to accidental impacts. Empty space in the mortar of settlement will compromise the resistance of ceramic tile.

    Any base to be coated with ceramic flooring (floor/wall), must be free of loose particles, dust, mudstone, paints, greases and oils, rubbers, and other. These types of finishes or dirt form a film preventing adherence and mortar anchoring on bedplate.

  • 7. Decorative borders with decoration in gold, platinum and luster need special care in the settlement and the day-to-day use?

  • These are products manufactured with special materials and noble furnished as: gold, platinum and luster. These noble products, since they are metallic materials, feature some characteristics:

    Effect on the decoration: dark spots featuring aged gold/platinum;

    Sensitivity to abrasion: we recommend caution in handling, settlement, grouting and cleaning on a daily basis. Alignment of the drawing: can present some imperfections to give greater artistic value.

    In the settlement, follow the guidance of Ceusa packaging, being careful not to apply the grout on the decoration of the gold, platinum or luster, protecting the decoration with the help of a masking tape or similar. On everyday cleaning do not use abrasive materials such as steel sponge. Only soft cloth and water.

  • 8. What are the main causes of ceramic detachment?

  • – Absence of the necessary joints for the system drive (dessolidarization, moving and structural);

    – Absence of roughcast not checking the grip required to grout anchoring of settlement;

    – Lack of adhesion of the mortar itself due to various settlement, as excess water in the dough, reuse of previously prepared mass, grout application in time open already exceeded, etc.;

    – Absence of joint compound (even in dry joint);

    – Existence of leakage or moisture;

    – Absence of double glue on plates above 30 × 30 cm;

    – Irregular Basis, with dirt, loose, uneven layers, etc.

  • 9. What is efflorescence and how to prevent it?

  • Efflorescence is the accumulation of soluble salts that are present in plaster mortar, roughcast and/or grout that along with water are brought out into the surface. Normally, the joints of spacing between pieces, but in more severe cases, the efflorescence reaches through the ceramic piece.

    It is important to note that efflorescence appears only if there is any leakage or moisture at the site, as it is the water that carries the salts to the surface forming a thick layer, usually hard and whitish color.

    The best way to avoid this pathology is to isolate the infiltration points (if any), respecting the times of healing in the execution of each stage of the work, not placing ceramic over wet basis (not cured), waterproofing masonry, prefer the Pozzolanic cement consumption, because it has lower salt content.

  • 10. How to increase the service life of ceramic tile?

  • – Always try to use doormats at the entrances of external doors;

    – Never use cleaning products that have acid in their formulation;

    -Pay close attention to the usage so as to choose the appropriate product for the location where it will be used;

    – Avoid contact of abrasives in shiny surfaces;

    – Protect the feet of the furniture with carpet or felt not to scratch the surface when dragged;

    -Avoid falling of heavy and sharp objects onto it.

    – The application of liquid wax is recommended for polished products to protect the surface.

  • 11. What is the warranty of the ceramic tiles and porcelain tiles produced with digital printing? Produced with nanotechnology, with Ceusa being the pioneer of the Americas in decoration with digital printing?

  • These are millimetrical particle composite coatings applied by the high quality enamel. Adding high performance products to the ceramic tiles and porcelain tiles for specification and use in: floors, walls and facades, according to their technical characteristics and properly specified.

    As the decor is cast on the surface of the ceramic plate, it does not suffer changes with time and exposure to weather.

  • 1. What are porcelain tiles?

    Productive Process Definitions
  • Porcelain is a type of ceramic tile manufactured with advanced technology. It differentiates itself from other coatings due to its burning process (high temperature), of the noble raw materials that make up its mass and also the water absorption is very low, being < 0.1% for technical porcelain tiles and < 0.5% for enameled porcelain tiles.

    This type of ceramic tile, which originated in Europe (Italy), began to gain prominence in Brazil in the early 90s. Porcelain tile has been designed for application of pavement, however, due to its high technical quality through its features it allows the most diverse usage possible, as for example: in front of buildings, etc. Its technology enables the reproduction of the beauty of natural stone, but with much higher technical characteristics.
