A specialized sealer coating, consisting of polyurethane applied over an epoxy sealer — a type of coating designed upon each case of fixation and texture — is used to preserve the surface appearance and enhance the long-term performance of the material. This coating provides UV resistance, colour retention and reduced water and vapour absorption, helping maintain MarmoFiber's original texture, finish and gloss over an extended period.
The coating can be applied at any stage following the initial installation and fixation, or during maintenance procedures, providing an additional layer of protection throughout the product's service life.
