Does Coloured Epoxy Grout Fade Over Time?

← Back to How do you colour epoxy grout?

Coloured epoxy grout is prized for its vibrant, lasting appearance, but many wonder whether those colours can fade with time. Here’s what you need to know to keep your grout looking its best.

Epoxy Grout and Colour Longevity

Epoxy grout is generally far more resistant to fading compared to standard cement-based grouts. This resilience is largely due to the use of high-quality pigments blended evenly into the resin system. However, no coloured surface is completely immune to change. Prolonged exposure to intense sunlight and UV can lead to gradual shifts in colour, particularly with vibrant hues and in outdoor or sunlit environments.

Choosing the Right Colourants

For grout that stays vivid, always opt for colourants specifically designed for use with epoxy resin. Products like Colourfun Liquid Epoxy Resin Colourant offer strong, stable hues with only small amounts needed. Paste sets and transparent dyes, such as those in the Colourfun or Magic Crystal ranges, allow further customisation of colour while reducing the risk of uneven fading and discolouration.

Care and Maintenance Tips

Whenever possible, avoid placing coloured epoxy grout in areas exposed to harsh, direct sunlight for prolonged periods.
Clean grout surfaces gently, as abrasive cleaners or harsh chemicals may dull colour over time.
Consider using translucent or lighter shades in outdoor settings, as subtle shifts are less noticeable than with bold or dark colours.
