Mending, levelling and smoothing of wall and ceiling surfaces

Surfaces of walls made of aerated concrete (siporex)

If AKRINOL is used to fix boards made of siporex (aerated concrete) instead of traditional building mortar, wall surfaces are almost ideally level. Therefore, thick-coat masonry plastering (traditional cement layer + traditional thick lime-cement render + traditional fine lime-cement render) can be replaced by an application of one or two coats of micro-reinforced LEVELLING RENDER. It adheres well to a demanding and unstable (as regards to volume) wall made of siporex (aerated concrete), dries quicker due to lower thickness, cracks substantially less at extending and shrinking of the wall due to changes in temperature and other changes, and, thus, presents an ideal substrate for fine levelling or smoothing (prior to painting) or for the application of one of thin-coated decorative renders. 
                                                                                      
Coat the surface of siporex (aerated concrete) wall 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)
