Substrate Preparation

• The substrate must be load-bearing, dry, and free of dust and substances that reduce adhesion.
• The base coat must be flush and even.
• Depending on weather conditions, the base coat may need to be primed beforehand or a universal primer such as weberprim 403 applied.
• Observe the curing times of the respective substrate.

Application

• During application and drying, the air temperature, materials, and substrate must not fall below 5°C.
• No additives should be mixed into the mortar.
• The mortar can be processed with all common plastering machines (see equipment planner) or by hand.
• Thoroughly mix the contents of a bag with the specified amount of water until a workable consistency is achieved.
• Apply the mortar to the substrate and smooth with a trowel to the desired grain size.
• Structure the applied material with a plastic float, wooden float, or PUB roller according to the desired pattern.
• To avoid color differences and joint marks, do not work with different tools, work wet-in-wet, and do not rework the surface once set.
• Work in joint layers to prevent joint marks, working in staggered layers.
