Levelling of wall surfaces made of aerated concrete (siporex) or surfaces treated with decorative renders, and polishing of surfaces painted with relief wall paints

Surfaces of decorative renders

The easiest way to level a more or less relief surface of decorative renders is to apply one or two coats of micro-reinforced LEVELLING RENDER. It adheres to the substrate well, dries quickly due to low thickness, does not crack when drying and presents an ideal substrate for fine levelling or smoothing (prior to decorative painting) or for the application of a new decorative render.                                                 

Coat the surface of a decorative render with diluted ACRYL EMULSION (ACRYL EMULSION : water = 1 : 1). Apply LEVELLING RENDER onto a still wet undercoat. It is applied in one or two coats in thickness of up to ~4 mm. First, impress vinyl-covered glass fibre mesh in size of ~50 cm x 50 cm as diagonal reinforcement into corners of wall holes, and special reinforcing corner angle bead on corners and reveal edges. If necessary (in case decorative renders, which are being levelled, are also severely cracked), micro-reinforce lower coat of the levelling render entirely in case of two-coat levelling using a vinyl-covered glass fibre mesh, which is switched at length and width for at least 10 cm.

for a m² of a levelling coat in usual thickness of ~4 mm, you will need
~120 g of AKRIL EMULSION (basic coat) and ~5.2 kilos of RENOVIRNI OMET

for diagonal reinforcement of corners of one wall hole, you will need ~1 m² of vinyl-covered glass fibre mesh, and to reinforce a m² of entire levelling coat, you will need ~1.1 m² ; to treat a m¹ of corner and reveal edges, you will also need ~1 m¹ of special reinforcing corner angle bead made of perforated aluminium steel-sheet or hard plastic reinforced with belts in width of ~20 cm of vinyl-covered glass fibre mesh.
