Kiilto OT Light is a lightweight plastering mortar for rock material wall surfaces. The finished surface can be painted or tiled. If a smoother surface is needed, for example under waterproofing membrane, the surface can be over plastered with Kiilto SK Märkätilatasoite, wall plaster for wet areas, or by floating with a steel trowel.

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 is dry. If needed, the surface should be carefully sanded and cleaned before applying a new plaster coat.
Strew Kiilto OT Light 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 by spraying and smoothen with a steel trowel. Can be applied with most common spraying guns for plasters, provided that the nozzle is big enough.
