Do I need to Seal Terracotta Tiles?
Yes — unsealed terracotta tiles must be sealed.
Terracotta is a natural clay product and is porous by nature. Without sealing, the tiles can absorb moisture, oils and everyday spills, which may lead to staining. Correct sealing protects the surface, improves durability and enhances the overall finish.
Choosing the Right Finish
Traditional Rustic / Antique Look
For a deeper, richer tone with a classic rustic feel, apply 2–3 coats of boiled linseed oil followed by 1–2 coats of antique wax.
This method darkens the tiles and grout and creates a warm, matt finish.
Natural Matt Finish (No Colour Change)
If you prefer to keep the original pale tone of the clay, apply 2–3 coats of C-10 Ultimate Sealer.
This is a breathable impregnating sealer that protects against staining while maintaining the natural appearance of the tile.

For kitchens, utility rooms or higher traffic areas, additional protection can be achieved by applying 1–3 coats of a satin stain-stop sealer after the initial impregnating coat. This increases resistance to spills and makes day-to-day cleaning easier.

Installation & Sealing Guidance
- Ensure tiles, adhesive and grout are completely dry before sealing.
- Apply one coat before grouting and two further coats after installation.
- Always test the sealer on a spare tile first, as absorption may vary.
- Avoid foot traffic for up to one week after final sealing to allow full curing.
- Follow the manufacturer’s instructions and your installer’s advice.
