Kiilto Pro Kerasafe Project

The Kerasafe Project waterproofing system is a waterproof and vapour tight foil for waterproofing wet rooms. An ultra-elastic and highly durable waterproofing membrane with a high crack bridging value. The waterproofing can be made ready for tiling in one single operation, and can be tiled as soon as 4 hours (walls) and 6 hours (floors) after application.

Instructions for use

Kiilto Pro Kerasafe Project is an elastic, watertight and vapour tight waterproofing membrane. The temperature of the material, room and substrate must be normal when installing Kerasafe Project membrane. The prevailing working conditions, including air humidity and temperature, have a significant impact on adhesion, drying time and possible dimensional changes of the waterproofing membrane. If carpet adhesive is used to apply the membrane, the surface must be tiled within 3 days of the membrane being applied. Read the procedure guide before starting the job.

Additional information

The information in this data sheet is based on our own research and practical knowledge. The technical values have been determined in standardised conditions. If the local conditions differ from these, they and the working methods will affect the values and the product’s functionality. The way the work is carried out also has a significant impact on the end result. Kiilto bears responsibility for ensuring that the product quality meets our quality system standards. However, the local conditions and working methods are beyond our control, and therefore we cannot be held responsible for the final result. To ensure proper product usage, the working instructions and procedure guide (if applicable) should be consulted.

Environment and safety

Wear protective gloves to avoid unnecessary skin contact with the product while applying it. Read the product safety data sheet. Please see our website for information on product and packaging disposal.
