Instructions for use

Please refer to the instructions for use in the Kiilto Block Barrier product brochure.

Mix the Kiilto Block Hardener thoroughly with the Kiilto Block Sealant. Follow the recommended mixing ratio exactly. Too small or too big an amount of hardener will result in incomplete hardening and in most cases too soft a result. Avoid contact with moisture. This might cause gas formation and viscosity to increase. Ensure good ventilation and wear suitable protective clothing.
