Instructions for use

The surfaces to be plastered must be sufficiently solid, clean and free from dust. Dry surfaces must be lightly moistened prior to plastering. A new coat should not be applied until the previous one has sufficiently cured. If needed, the surface should be carefully sanded and cleaned before applying a new plaster coat. Protect the surface from direct sunlight and windy.

Strew Kiilto KL powder slowly in cool (+18–20 °C), clean water constantly stirring until a smooth, even mass is formed. Let the mix mature for approx. 10-15 min and then remix once again. Apply Kiilto KL by spraying or by vigorously pressing it onto the substrate by hand. Sprayed surface can be levelled, for example, with a steel trowel. The surface can be floated.
When using Kiilto Rappausverkko -reinforcing mesh embed it into fresh plaster. Smooth the surface with a steel trowel to leave the mesh in the middle of the plaster layer. After the layer has cured, the second layer can be applied. In dry conditions, curing of the layer can be speeded up by spraying it with water.
