Kiilto Kerafiber system

An efficient waterproofing system for building bathrooms and other indoor wet rooms.

Versatile and durable system for wet room construction

Kiilto Kerafiber was developed in response to builders’ need for an efficient and user-friendly waterproofing solution for various applications. A comprehensive system has been designed around the microfiber-reinforced waterproofing membrane, enabling the efficient construction of wet rooms from base to finish.

The Kiilto Kerafiber system is suitable for floor and wall surfaces where ceramic tiles are used. In addition to bathrooms and other wet rooms in residential buildings, the system is also ideal for public buildings, schools, and sports halls. Kiilto Kerafiber is not recommended for areas with constant water exposure (e.g., swimming pools). In addition to roller and brush application, the membrane can also be sprayed, offering significant time savings.

Durable wet room

At the core of the system is a microfiber-reinforced waterproofing membrane. Effective structural protection keeps spaces healthy and safe.

Professionals’ choice

Kerafiber is designed to meet the demands of professional wet room builders. It has already been chosen for hundreds of thousands of wet rooms.

Nordic expertise

Kiilto Kerafiber waterproofing membrane is developed and manufactured at Kiilto’s factory in Finland.
