Frequency of tests
Tests to monitor the effectiveness of the TiO2 coating are conducted on a regular basis.
- Before the application
- After the application
- Every 3 months*
*more frequently for special cases ofapplication
Surface contamination negative tests
These tests are carried out with a professional ATP Monitoring System (bioluminometer). Adenosine Triphosphate, a.k.a. ATP, is the energy molecule found in all living and once-living organisms. With an ATP hygiene monitoring system, swab samples are taken from control surfaces and tested for ATP presence, measuring the level of organic contamination in seconds, allowing to verify that the TiO2 coating is effective and that organic contamination is below safe target values.
Surface contamination positive tests
Every client receives a white ceramic tile as a test sample, treated with the same product and at the same time of the other spaces. This sample is regularly contaminated with methylene blue (an organic stainer) or with a red organic ink and the effectiveness of the treatment can be visually verified, as the tile, covered in blue/red, will turn back to the original white color after exposure to direct sunlight if the coating is still effective.
Air contamination tests
These tests are carried out with a professional HCHO/VOCs air quality meter.Formaldehyde and volatile organic compounds (VOCs) are the most dangerous substance groups with regard to indoor air exposure. Both concentrations are read simultaneously in real time during tests to ensure that the room air pollution is harmless and remains within safe target values.
