Application steps

MIXING

SikaWall®-198 Finish 2-in-1 must be mixed with clean water at the site using a power drill whisk. Pour the required water into a clean container then add SikaWall®-198 Finish 2-in-1 while stirring continuously until a smooth consistency is achieved. Allow mixture to stand for a few minutes. Mix again and the plaster is ready for use.

 

APPLICATION

Use a steel trowel for application while the mix is still workable. Apply at the recommended thickness of 1–3 mm per layer and up to a total build-up thickness of 6 mm. Ensure that each layer is dry before applying the subsequent layer. SikaWall®-198 Finish 2-in-1 can be finished with a soft brush or trowelled smooth.

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened or cured material can only be removed mechanically.

FAQ

What are skim coats?

Skim coats are fine mortars applied onto walls and ceilings to a thickness of 2–3 mm to create a flat, smooth and uniform surface, to be painted or re-textured. As a guide, you should apply at least two skim coat layers to achieve a smooth and consistent surface.
