Have you ever visited a friend’s house or toilet in the airport, train station and noticed how dirty and stained the grout is?
Grout is one of the most porous surfaces in our world. Tiles and grout get splattered with fat in the kitchen and also in the shower / bathroom up to about head height.
If you clean and then treat the grout…..sealer is available in almost any colour you can think of…..then that grout is now protected for between 8-10 years. Some will provide guarantees up to 15 years
