Factors that affect grout color
- Grout type: Cement-based grout is common and tends to turn gray over time.
- Mixing: Adding too much water or mixing partial bags can cause color variation.
- Cleaning: Cleaning grout too soon or with too much water can cause color variation.
- Substrate: The density and porosity of the tile or stone can affect the color.

- Manufacturer: Different batches of grout from the same manufacturer can have different colors.
Popular grout colors

Tips to reduce color variation
- Use grout sealers to reduce the effect of grout turning gray
