At Nordic Chem we stand by our protection time and go the extra step in ensuring our customers an active antimicrobial coating for that time period.
At the point of application the installers place test stickers on discrete parts of the surfaces being coated. Half of the testing sticker is coated and the other half is left untreated. The installer will return to your premises every 30 days with a solution that tests for the activity of the presence of a biocide (antimicrobial activity) on the surfaces.
This is done in the presence of your business representative. The testing solution will be applied to both sides of the sticker and on the side of the testing sticker that has been coated, the solution should change colour. On the untreated side, the solution should remain unchanged.
