Increase Ceramic Floor Tile PEI Rating with Kastus

Kastus Ceramics is a glaze that can achieve a PEI (Porcelain Enamel Institute) rating of 4 or greater for your floor tile surface, regardless of tile color. Ceramic tile manufacturers are challenged to create products that are safe and superior to competitors. The aim is to produce a technically sound tile with high scratch and stain resistance, while also being aesthetically pleasing, durable and cost-effective.

The Solution

We’ve developed a multi-purpose glaze that adds value to ceramic tiles through enhanced physical, chemical, and biological functionalities. Kastus Ceramics is an ISO-certified solution that creates life-long stain and scratch-resistance on the tile surface. Check out our Kastus Ceramics technical document to know more about Kastus Ceramics' ISO testing and PEI ratings.

Floor tiles featuring Kastus Ceramics are more durable than the average ceramic tile. However, that’s only useful if consumers can still benefit from elegant, beautifully-designed tiles. Well, they can.


Does Kastus Ceramics affect the appearance of tiles?

Kastus Ceramics spray does not affect the tile appearance in any way, regardless of the tile color. The glaze is sprayed onto the ceramic surface prior to firing and sinters onto the surface. This leaves a clear, invisible finish so that your beautifully-designed ceramic tiles keep their uniqueness while gaining all the benefits of Kastus technologies.

Do I need a second firing on ceramic tiles when using Kastus Ceramics?

No, a second firing is not needed. Kastus Ceramics allows you to increase your ceramic floor tile PEI rating with just one firing. Kastus Ceramics is sprayed onto the surface directly before firing with no extra production steps required.


To summarize, Kastus Ceramics glaze is a value-adding technology. It allows ceramic floor tiles of all colors to achieve a PEI rating of 4 or greater, with no extra firing during the manufacturing process.
