What makes the white grout dark?

Grout is a composite material consisting of water, cement, and sand. It is typically used for filling voids under machines or other structural elements, sealing joints and openings in surfaces and reinforcing existing structures. 

Grout materials are divided into 3 main types: cementitious grouts composed of a Portland cement base; epoxy grouts, and furan grout. Epoxy grouts, which are white color, are the most preferred material used for ceramic tiles. 

However, the biggest problem of grout lines is that once the grouting material becomes hard, the surface is not sleek like ceramic tiles and it is not glazed. As a result, even if you wipe the floor on a daily basis, dust and debris will still cling to the lines again causing the color changing.

Temporary whitening of the grout: There is a tool called grout pen which is designed specially for treating stained grout. A grout pen applies a layer of waterproof paint on top, which can be tinted to match the colour of your tile grout, covering any stains. Many grout pens also contain ingredients to combat mould and mildew, and are available at supermarkets and most hardware stores. However, the layer can not resolve the main root of the stain and the paint won’t stay permanently. Therefore, this solution is not a thorough solution, you still need further cleaning processes to get a long-lasting result.

How to keep white grout clean

Staining and damage resistance must be an outstanding feature of many types of tiles. Grout, on the other hand, wasn’t born with the same self-protecting ability as tiles. Without sealing, the grout can easily be stained, or absorb liquid causing darkening. However, white maintainaning is not a complex task. 

Obviously, regular cleaning is the best way to prevent your white grout lines from darkening. For high travel density or humid areas, such as the bathroom, you should at least swipe the floor of your toilet once a day after showering. Aegle and mildew won’t have a chance to settle in the grout once it is removed immediately.

Not only that, using a high quality sealant to seal the grout is an effective way to protect the grout from dirt and germ.
