Decorative renders

SILICONE 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
• 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
• wide selection of colour shades
• highly water-repellent, therefore, it is suitable also for façade surfaces of tall buildings, which are extremely exposed to precipitation; water repellence abates very slowly, therefore, soot, dust and other dirt adhere to processed surfaces less and later application is possible also in less favourable weather conditions

Coat the substrate with UNIGRUND or diluted JUBOSIL F (JUBOSIL F : water = 1 : 1); - in both cases, the shade should be in the shade 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 m²of the surface, you will need ~150-200 g of UNIGRUND or  
~120 ml of JUBOSIL F and ~2.8 kg of SILICONE TROWELLED RENDER 2.0 or 3.5 kg of SILICONE TROWELLED RENDER 2.5.
