Application steps

MIXING

Pour the recommended amount of clean water into a suitable mixing container. Gradually add SikaWall®-168 Plaster EM while mixing continuously using a low-speed electric mixer (approximately ~500 rpm) to minimize air entrainment.

Mix for at least 3 minutes until a homogeneous, lump-free mortar with a smooth and workable consistency is achieved.

Allow the mixture to mature for 2–3 minutes, then remix briefly before application.

APPLICATION

Apply SikaWall®-168 Plaster EM onto the prepared substrate using a steel trowel, pressing firmly to ensure good contact and adhesion.

Apply in a uniform layer with a recommended thickness of 3–8 mm per coat. For thicker build-up, apply in maximum 2 layers. Allow the first layer to set until tack-free before applying the second layer.

Level the surface using a straightedge, then finish with a steel or wooden float to achieve the required surface texture.

Apply at ambient temperatures between +5 °C and +35 °C. Avoid application under direct sunlight, strong winds, or rain. For external areas, provide suitable protection (e.g., shelter) to prevent exposure to sun and rain during application and early curing. It is the user’s responsibility to assess the condition and suitability of all substrates prior to application.
