Mending, levelling and smoothing of wall and ceiling surfaces

One-coat levelling of unplastered concrete ceiling surfaces

First, clean the substrate of loose and badly-adhered particles and then apply NIVELIN D. Do not apply any of primers prior to the application of NIVELIN D. Apply only one coat of levelling compound in thickness of ~1.5 to 5 mm either manually – using a stainless steel smoothing trowel – or by machine – by spraying. Regardless of the manner of application, remove excess compound from the treated surface using a stainless steel smoothing trowel, while trying to level the surface as much as possible. Moisten the surface of the application approximately 10 to 20 minutes after the application (it can be done sooner or later depending on the microclimatic conditions and absorbency of the substrate, but no sooner than when the compound begins to harden) and smooth it with circular movements using a smoothing trowel made of expanded polystyrene, wood or plastic. If necessary, additionally sand the dry application using fine sandpaper after 2 to 5 days. The wet smoothing phase can be left out and entirely replaced by dry sanding, which is performed manually or by machine.

for ~ 1 mm thick application on m² of the surface, you will need ~1.5 kilo of NIVELIN D
