Rustins Ceramic Glaze Clear 250ml
Rustins Ceramic Glaze is a water-based finish designed for ceramic tiles where a clear, non-yellowing glaze is desired. It dries quickly and is formulated to resist cracking or crazing over time. The glaze is noted to be suitable for stoving, offering an option where heat-curing is possible. Best for general purpose tile protection in kitchens, bathrooms, and accent areas where a clear, glossy layer is preferred. Limitations may include surface preparation requirements and re-coating intervals depending on traffic.
CoverTec GlazeGuard High-Gloss Tile & Grout Sealer
This two-component, water-based glaze/sealer forms a high-gloss “wet look” film across tile faces and grout joints. It bonds to glazed and unglazed, porous and non-porous surfaces including ceramic, porcelain, and stone tile. With a durable barrier designed for 3–5 years, it helps resist water, dirt, odors, and abrasions while maintaining color clarity. Choose this if you want a long-lasting glossy finish that’s relatively easy to wipe down. Caution: proper mixing and ventilation are important for best results.

It forms a transparent layer that resists cracking and scratching, preserving color and details on tiles crafted from air-dried clay or similar surfaces. Best for hobby projects, small craft tiles, and decorative pieces where a durable, glossy finish is desired without baking. Limitation: it requires 24 hours to fully dry for complete cure, which affects project timelines.

It uses nanotechnology to deliver long-lasting repairs with strong adhesion and a color-matching approach.

Limitation: the two-part mixing adds steps and requires precise follow-through to achieve optimal performance.
