Grout Colouring
When deep seated grout stains become impossible to remove, regrouting is often the most discussed solution. However, this is a messy and time-consuming process with no guarantee the grout will not become stained again in future. A quicker and more effective solution is to apply an epoxy grout colourant which as well as transforming the appearance of the grout also adds a barrier over the surface that protects it and makes it much easier to clean.
