Trowelled decorative renders

SILICATE TROWELLED RENDER 2.0 and 2.5

• typical appearance similar to traditional Bavarian render or oak bark
• two granulations: 2.0 and 2.5 mm
• wide selection of colour shades
• supplied in paste-like form, ready for application
• application to all kinds of fine plastered substrates including that of facade thermal insulating systems is possible (regardless of the type of insulating lining)
• highly water-vapour permeable application in less favourable weather conditions (low temperatures, high atmospheric humidity) is not possible (spots)

Coat the substrate with UNIGRUND or a mixture of JUBOSIL FX, JUBOSIL GX and water (JUBOSIL FX : JUBOSIL GX: water = 1 : 1 : 1) – a shade of UNIGRUND and JUBOSIL FX should be as close to the colour of the render as possible. Apply mortar compound in thickness of the largest sand grain manually (using a stainless steel smoothing trowel) or using a machine (by spraying) onto a dry pre-coat. Rub the compound circularly, horizontally or vertically by a smoothing trowel made of expanded polystyrene, solid plastic or wood. A few minutes after rubbing, push mortar lumps sticking out of the render surface into the surface by smoothing the surface slightly using a clean stainless steel smoothing trowel.      


The joining of surfaces in corner edges is facilitated by installing finely smoothed stripes which have got a width of only a few centimetres. Such stripes are recommended also when dividing big façade boards to several smaller ones to avoid any trouble at application of the render and unaesthetic appearance due to a surface, which may not be even enough, and, at the same time, by applying the stripes interesting decorative effects can be achieved.

To process a m² of the surface, you will need ~150 to 200 g of UNIGRUND or ~80 ml of JUBOSIL FX and ~80 ml of JUBOSIL GX (a small amount may be used for eventual diluting of the render) and ~2.5 kg of SILICAT TROWELLED RENDER 2.5 or ~3,2 kg of SILICAT TROWELLED RENDER 2.5
