Instructions for use

The surfaces to be plastered must be clean, dry and free from dust. A new coat should not be applied until the previous one is dry. If needed, the surface should be carefully sanded and cleaned before applying a new plaster coat.

Strew Kiilto LK powder slowly in cool (+18 °C), clean water constantly stirring until a smooth, even mass is formed. Let the mix mature for approx. 15 min and then remix once again. Apply the plaster by hand with a steel trowel or spray with a spraying gun for plasters. Also, the sprayed coat should be levelled by hand with a steel trowel. If left over plaster is saved for the next day, the container should be covered carefully to avoid drying.
