Say Hello to Intelligent Ceramics

Lifeker Plus+ is an antimicrobial-treated finish that can be added to the glaze of any ceramic tile. The Microban® technology featured in Lifeker Plus+ disrupts the metabolism of bacteria by preventing conversion of nutrients into energy, helping to inhibit bacteria survival on a ceramic surface.

Embrace Cleaner, Fresher Surfaces

Staining and bad odours can be caused by excess bacteria proliferating on a surface. Through its antimicrobial properties, Lifeker Plus+ works to minimise the presence of damaging bacteria, helping to preserve the aesthetic properties of a ceramic surface.

Benefit from Around-the-Clock Protection

Lifeker Plus+ features a protective shield that keeps working day and night, without the need for sunlight or activation via ultra-violet rays. The finish is functional in both indoor and outdoor spaces and even under LED light.

Relax. It’s Safe to Use!

Silver (Ag+) is a key ingredient of Microban® SilverShield® technology, used in the development of Lifeker Plus+. SilverShield® has undergone extensive independent laboratory testing and has a long history of safe use.

The biocidal active components of SilverShield® are registered with the US Environmental Protection Agency (EPA) and included in Article 95 of the EU Biocidal Products Regulation (BPR).

The Superwhite Collection: An All-Round Sensory Experience

Keraben's desire for continuous innovation has resulted in the development of Superwhite. This collection of ceramic walls tiles has been independently certified as the whitest tile collection on the market*.

In addition to having no perceptible roughness at all, Superwhite ceramic tiles are also protected with Lifeker Plus+. These additional features ensure the tiles are easier to clean and remain cleaner in-between cleanings.
