Amtico flooring is hard wearing and comes with a factory UV cured PU finish, however it is recognised that it will benefit from being topically sealed to prevent excess wear and scratching to the tile surface.
Amtico dressing is the recognised product to regularly apply to the surface, it will maintain the correct sheen level and prevent surface scratches appearing on the tile surface from general use. Once the Amtico dressing has started to wear after generally 6 months, it is common practice to strip and reseal the floor.
If you want a more long term sealing solution for your Amtico floor, a permanent PU sealant can be applied that will last in excess of 3 years. These won’t alter the appearance of the floor but will give greater longevity.
