Choosing the correct sealer is an essential part of using terracotta tiles properly. The right product will protect the surface, control staining and help you achieve the finish you’re looking for — whether that’s a light, natural appearance or a richer, more traditional look.
The best sealer for your project depends on where the tiles are being used, the finish you prefer, and how much protection is required.
Step 1: Where are the tiles being used?
Interior floors
Most interior terracotta floors require a penetrating or surface sealer to protect against everyday spills and dirt. Kitchens and high-traffic areas benefit from higher protection.
Sheltered external areas
External terracotta tiles require sealers designed to cope with moisture and temperature changes. These are typically breathable and offer enhanced protection.
Step 2: What finish do you want?
Natural / Matt finish
If you prefer the most authentic, light appearance with minimal colour change, a natural or matt sealer is usually the best choice.
Enhanced / Antique finish
If you’d like to deepen the colour of the terracotta and create a warmer or more traditional look, colour-enhancing sealers, oils or antique finishes can be used before final sealing.
Step 3: How much protection is needed?
-
Light-use areas may only require basic protection
-
Kitchens, entrances and busy spaces benefit from stronger sealers
-
External areas require products suited to moisture exposure
The correct system often involves more than one stage, particularly for interior floors.
