In areas subject to agents such as oil, grease, fat and excessive humidity, we recommend the use of sealants on the Arquitetura Natural Line ceramic tiles (class 1 stains). There are two basic types of sealant: those that form a film, such as acrylic resins, which make the floor darker, smoother, and shinier and alter the original characteristics of the tiles; and those that do not form film, such as water and grease repellents, which do not change the initial characteristics of the tiles such as the color, texture and brightness. Both should be applied by skilled labor and according to supplier recommendations.
There are three types of cleaning and each requires specific care: - post-work cleaning: done before the work is delivered to remove grout remains. Made from hydrochloric acid (HCl)-based detergent, it should be done only once to avoid chemical corrosion of the grout. Follow specific Gail Manual guidelines available on our web page. Never use products containing hydrofluoric acid (HF) and/or its derivatives, such as stone cleaners, and/or products of doubtful origin. Always contact the supplier for clarification; - daily cleaning: done with neutral, phosphoric or citric-based acid or an alkaline; - maintenance or periodic cleaning: the frequency of this type of cleaning will depend on tile use. It can be weekly, twice weekly, monthly, yearly or even less frequently (facades, for example, are cleaned every 5 years at most). This type of cleaning requires more concentrated, professional products. We recommended this service be performed by truly skilled labor to avoid damage. Never use products containing hydrofluoric acid (HF) and/or its derivatives, such as “stone cleaners”, and /or products of doubtful origin. Always contact the supplier for clarification. Contact the Gail Technical Department for further clarification.
Floors: correctly follow the specifications of the person responsible for the work regarding the sloping; preparation, thickness and curing of the sub-floor; preparation, application and curing of the laying mortar; layout planning, execution and caulking of movement joints; preparation, application and curing of grout (mainly on external floor) and layout of the tiling. Additional information and care instructions can be found in standard NBR 13753/96; Industrial floors: follow recommendations specific to each type of work according to the executive project; Walls and facades: correctly follow the specifications of the person responsible for the work reagarding the thickness and curing of the plaster; preparation, application and curing of the laying mortar; the tile layout planning, execution and caulking of the movement joints; preparation, application, curing and cleaning of grout and layout of the tiling. For further information and care instructions, see standard NBR 13755/96.
Facades: for facades the choice of product depends on the esthetics desired as well as on the technical conditions necessary for good performance. These technical conditions bascally concern weather protection, protection against fading due to UV radiation, easy maintainance and resistance to aggressive agents such as salt spray, acid rain and pollution. Water absorption of facade cladding must be under 6%; in regions subject to temperatures below 0°C, recommended absorption is under 3% (higher freeze resistance); Pools: In swimming pools, the tiling must basically be resistant to UV radiation and chemical agents present in the water. In sports pools, such as those for acquaerobics, and on steps, we recommend the floor be covered with non-slip ceramic tiles. For the outer corners of the walls, L-shaped pools, and the edges of the steps and the pool, the use of rounded parts offers greater comfort to users, thus preventing accidents; Flooring: - external areas: we recommend using non-slip tiles, whose friction coefficient is greater than 0.4, preventing accidents from happening; - internal areas: there is no specific recommendation on the friction coefficient of the tiling; - high traffic (internal and external): We recommend use of PEI 5 (Minerale Rústico Line) and Unglazed (Arquitetura Natural Line) plates; Industrial: the ceramic tiling used in industry must meet the mechanical and chemical requirements for each specific case. The Gail Industrial Line has ceramic plates and finishing pieces to suit all industrial needs. Plate thickness can be 9, 14 or 17 mm, depending on the local mechanical overload, type of load carrier (forklift, pallet truck, trolley, assorted trucks, etc.) and wheel type (metallic, pneumatic, solid rubber, polyurethane, etc). The chemical resistance of the Gail Industrial Line plates is very broad, covering almost all products used in industry, and particularly facilitate asepsis in food preparation areas.
PEI stands for Porcelain Enamel Institute, which is the name of the institution that developed the Surface Abrasion test method for glazed (enameled) ceramic tiles. This test measures the surface wear of the enamel layer of the plates and ranges from 0 to 5, in line with Brazilian technical standard NBR 13818. Deep Abrasion is the test that measures the physical and mechanical wear and tear suffered by the body of a non-enameled ceramic plate. It is a more severe test than the PEI, but they cannot be compared. In practical terms, in a high traffic area non-glazed ceramic tiling has longer durability than PEI 5.
