One of the main actions taken and recommended by the authorities to minimize the spread of Covid-19 is the disinfection of spaces. This is often done with aggressive chemicals that, given their toxicity, impact the treated coating materials, human health and ecosystems. But do all cladding materials equally resist intensive disinfection?

Faced with this question, Keraben Grupo, together with ITC-AICE, has carried out an exhaustive comparative study of the response of cladding materials to the use of disinfectant products, from which it can be inferred that ceramic products rank as one of the the most hygienic solutions and whose qualities last better over time when they suffer the chemical attack of these products. Compatibility with the disinfectants of the different types of materials used in the coating of the surfaces can become key in case of microbiological threats future, helping to reduce the number of infections.

After this study, it is confirmed that Ceramic remains unaltered against the attack of these chemicals and is positioned as a safe and sustainable solutionfor both indoor and outdoor use. In addition, it allows a more rational use of disinfectant products, identified in many cases as dangerous to human health and the environment. Do not forget that abuse of these products has environmental implications clear, since they end up in the public stormwater sewerage system (exterior disinfection) or affecting wastewater treatment (interior disinfection), due to the increased toxicity of said waters.


Some of these substances are considered toxic to aquatic life and are corrosive to the skin, and can cause serious burns and damage to the eyes. It is therefore necessary make the use of these products compatible with respect for the environment, without compromising the quality of life of future generations.

The study has covered 21 types of materials: 5 different types of ceramics in use for paving; 3 different types of PVC-based products and 3 types of laminated products; 3 types of wood in dark, light and multilayer tones; 2 types of carpets with natural fibers and 2 types of carpets with synthetic fibers; and 3 different types of stones and marbles.

All materials have been subjected to the effect of the following chemical products for cleaning and / or disinfection: bleach, ammonia, caustic soda, citric acid, salfumán, lactic acid, hydrogen peroxide, acetone, sanitizer (based on didecyldimethyl ammonium chloride) and disinfectant (based on Biphenyl-2-ol + ethanol).


The tests have reproduced in the first place a conventional cleaning with the dilution recommended by the manufacturers of the chemical products, with a subsequent rinsing and without it, and secondly an accidental spill of said products in the direct concentration of their container, considering its rapid detection and removal, or leaving it a day without removal.

From the results of the study it can be deduced that, in the materials with the greatest degradation, a possible cause derived from the increase in surface texture / roughness is that the intensive use of disinfectants could not only affect the loss of their aesthetic qualities and technical performance, but also could favor the fixation of certain microorganisms, fungi, bacteria and viruses, which would require more use of disinfectants over time.

The ceramics stands out as one of the materials most resistant to disinfectants becoming one of the most hygienic and durable materials.
