Application

Suitable for all standard and high thermal insulation masonry types made of bricks, aerated concrete, Liapor, etc., as well as precast concrete panels and other wall substrates that are still to be overcoated with a top coat. Pre-treatment of the substrate is necessary on various surfaces.

As an interior and exterior primer, as well as for small-format tiles (60 x 30 cm) in residential buildings and kitchens.

Execution

Apply Super Lupp to prepared substrate in a minimum thickness of 15 mm, trowel flat, and smooth. For Mak3 as a top coat, apply at least 15 mm of Super Lupp in a full coat, trowel smooth, and then roughen with a coarse trowel. Embed a surface-reinforcing mesh 8x8 mm if needed. Depending on the substrate, ridges and unevenness can be removed after approximately 2 hours with a grid trowel. Conduct a scratch test with the grid trowel.

Super Lupp is a fast-setting material. Spraying interruptions are a maximum of 15 minutes, or up to 25 minutes in warm weather. During longer pauses, clean the mortar and spray equipment. Do not leave the mortar or spray equipment in the sun. Material that has set cannot be processed further.

Preparation

Normal absorbent substrates can be plastered without pre-treatment. On highly absorbent substrates, apply wet-on-wet, with a layer of 5-10 mm first, followed by a second layer up to the required plaster thickness, also wet-on-wet. On non-absorbent substrates, a mineral adhesion bridge with SM700 Pro, SM300 Base, SM or Lustro must be applied.

Application

For pre-treatment of the substrate, allow the applied primer to dry completely. Render is usually processed with a mixing pump, e.g., PFT G4/G5, which is particularly efficient and time-saving. It can also be applied manually with a trowel. Distribute the plaster evenly with a trowel or straightedge and smooth after initial setting, then re-scrape.

Drying

The finished base coat must be completely dry before further coating. The drying time depends on the thickness of the plaster and external conditions such as weather and temperature. To prevent too rapid drying, exterior renders should be protected from direct sunlight. Generally, the minimum drying time is 1 day per mm of plaster thickness.
