Mixing
Machine application: For machine application using mixing pumps, e.g. PFT G4, set the desired consistency by adding water.
Hand application: Mix the content of one bag with about 5.6 litres of clean water without further additions until an application-ready lump-free consistency is achieved. When mixing, use clean water and do not add other additives. Clean the machines and tools with water immediately after use.
Application
Apply UP 210 on a pre-prepared substrate with a plaster thickness of at least 10 mm (interior applications) or at least 15 mm (exteriors), strike off level and scrape. Remove fins and protrusions with a lattice plane after initial setting. Undertake scratch tests with the lattice plane. Before working area further, allow to dry and harden at a rate of at least 1 day / mm
thickness.
With normally absorbent substrates, such as e.g. brick, pumice, expanded clay or aerated concrete masonry, UP 210 can be sponged with a single layer. On large area concrete surfaces to be plastered, large format lime sandstones etc., where a primer is necessary in accordance with the above table, apply and sponge another 2-3 mm of UP 210 on the following day.
With Mak3 as a top coat apply at least 10 mm UP 210, strike off level and subsequently roughen with a coarse brush.
Render thickness
Single-layer or double-layer: 10-35 mm.
Single-layer 10-20 mm: Drying time min. 1 day /mm.
Single-layer > 20-35 mm: Drying time min. 1 day/ mm and a further week per cm of additional render thickness exceeding 20 mm. After fully dry and set, apply full surface mesh reinforcement (reinforcing mesh 4×4 or 5×5 mm) with SM700
Pro, SM300 or Lustro.
Two-layers > 20-35 mm: Apply the first layer and and roughen with a brush. Allow the first layer to dry for at least 1 day /mm. When fully dry and set, embed basecoat mesh (8×8 mm) on the full area just below the surface in the second layer.
Or after fully dry and set, apply full surface mesh reinforcement (reinforcing mesh 4×4 or 5×5 mm) with SM700 Pro, SM300 or Lustro.
