Can I use linseed oil or wax on terracotta tiles to change the color to a darker tone?
Our customer shares a DIY method for this on Organic Terracotta tiles.
How can I darken the color and tone of Organic Terracotta tiles?
You can darken Organic Terracotta tiles by sealing them three times with linseed oil and finishing with a brown wax polish such as Fiddes & Sons Supreme Wax in Rugger Brown. The following documents a customer-applied method for achieving this result.
Because these tiles are supplied without a factory seal, they readily absorb treatments that alter their color and tone.What steps are involved in darkening Organic Terracotta tiles with linseed oil and wax?
The full process takes approximately one week and involves the following steps, performed in order:
- Apply the first coat of linseed oil and allow it to soak in for one full day.
- Apply the second coat of linseed oil and allow it to soak in for one full day.
- Apply the third coat of linseed oil and allow it to soak in for one full day.
- Apply Fiddes & Sons Supreme Wax polish in Rugger Brown as a finishing treatment to deepen and enrich the final color.
- Grout the tiles and clean up the grout haze; repeat this clean-up step on three separate occasions until the desired outcome is achieved.
We are pleased to share the final result:


Is this darkening method officially supported by Clay Imports?
No. This method was applied independently and falls outside Clay Imports' standard installation and sealing recommendations. Results will vary depending on application technique, environmental conditions, and tile batch. We recommend consulting a professional installer before attempting a similar process and testing any treatment on a sample tile prior to full installation.
