Instructions for use

The surfaces to be plastered must be clean, dry and free from dust. Indoors, dry porous surfaces should be wetted with water before plastering or treated with a mixture (1:4) of water and Kiilto Pro Start Primer or Kiilto PrimerOne. 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 LH 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. Bond strength, impact resistance and durability of the plaster can be improved by replacing 10 % of the mixing water with Kiilto Pro Start Primer or Kiilto Pro Primer 001. 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.
