Application purpose:
For all normal, thermal insulating and high thermal insulating masonry types made of bricks, aerated concrete, Liapor etc., as well as precast wall panels and other wall substrates to be finished with a top coat.
Pre-treatment is necessary on various substrates.

As an interior and exterior base coat
As a base coat for small-format tiles (? 60 x 30 cm) in domestic bathrooms and kitchens

Application:
Apply Super Lupp in a minimum thickness of 15 mm onto prepared plaster substrate, trowel evenly and finish with a darby. For top coats with Mak3, apply at least 15 mm of Super Lupp fully covering, trowel in a straight line and then roughen with a coarse brush. If necessary, embed a surface near substrate reinforcement mesh 8x8. Depending on the substrate, ridges, unevenness etc. can be removed after approx. 2 hours with the grid trowel. Perform a scratch test with the grid trowel. Super Lupp is a accelerated material; spray interruptions are a maximum of 15 min. (up to 25 min in cooler weather). For longer breaks, clean machine and hoses. Do not leave mortar and water hoses in the sun. Process material that has set.

Preparation:
Normal absorbent substrates can be plastered without pre-treatment. On highly absorbent substrates, apply wet-in-wet. First apply a layer of 5-10 mm and then apply the second layer wet-in-wet up to the required plaster thickness. For non-absorbent substrates, apply a mineral adhesion bridge with SM700 Pro, SM300, Base Coat-SM or Lustro.

Application:
After pre-treating the substrate, allow the primer applied to the substrate to dry completely. Base coats are usually processed with a mixing pump, e.g., PFT G4/G5, which is particularly efficient and time-saving. They can also be applied manually to the wall. Afterwards, distribute the plaster evenly with a trowel or straightedge and finish with a stiffening trowel.

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