Guaranteeof ALTA^KEEM’s effectiveness and duration related to the following fields of application

SPECIAL Applications
6 months (or less)

Treatments conducted in non-standard application conditions, such as - but not limited to - areas subjected to high superficial wearing due to physical friction or due to rotary cleaning with rotary brushing systems or due to the natural wearing & tearing of the surface in high passage areas, will be warranted for 6 months or less, with a specific assessment done on a case by case basis.

STANDARD Applications
12 months

Treatments conducted in standard application conditions are warranted for 12 months from application. Such duration under standard conditions of application has been certified based on an accelerated weathering/ageing test according to ASTM G154/12a standard and subsequent testing according to BS ISO 27447:2019 standard.Our service will be also proven, for the client’s future reference, by a QR Code, which will provide all the useful information and images related to the application of our sanitizing procedure of that specific location.


ALTA^KEEM’s effectiveness is monitored periodically for the entire duration of the    warranty period

Frequency of tests

Tests to monitor the effectiveness of the TiO2 coating are conducted on a regular basis.

- Rapid test before the application
- Rapid test after application(with bioluminometer)
- Every 3 months*

Surface contamination negative tests

These tests are carried out with a professional ATP Monitoring System (bioluminometer before and after Treatment). 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. An optional post treatment Monitoring Service is also available.

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 before & after Treatment.
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.

*costumer may elect to receive monitoring services every 3 months or more frequently for special cases of application,with the conduction of Total Plate Count (TPC) test by a 3rd party independent & accredited microbiologi lab.
