Even though to the naked eye, glass looks like a solid smooth surface, at the microscopic level, it's quite porous. This is what allows minerals to sit on the surface of the glass. The optional glass coating we apply to your shower seals the glass to create a surface barrier to keep those pesky water spots off the glass and make it easier to remove them from the coating. The coating is an ultra-thin layer that is permanently bonded to the glass and is completely invisible to the eye. It cannot chip or flake off, and has a VOC of zero.
Similar to a non-stick pan, it's important to continue to squeegee and clean your shower glass like you would normally. The coating is designed to help provide some stain resistance and also to make it far easier to clean any staining off.
The cost of glass coating is calculated per panel, and we're happy to add it to your quote. Coating is applied at the manufacturing stage, so needs to be ordered along with your shower glass.
The warranty on the glass coating is for ten years. Please see Care Instructions to assist in caring for your glass shower and its coating.
