Keim Brillantputz Rauputz is a high quality, mineral thin layer, lightweight rough render made from mineral binders and high-quality fillers. Suitable as a finishing render for all level mineral substrates and as a top coat for Keim Universal Render. Suitable for subsequent application of Keim Mineral Paints.

Top Features & Benefits

• Water absorption: w < 0.5 kg/m² h 0.5.
• Diffusion resistance: sd = 0.1m.
• Grain size: 2mm, 3mm and 5mm.

Preparation & Application

Substrate Preparation
All loose, flaking and unstable material must be identified and then thoroughly removed, all surfaces must be thoroughly washed down with clean cold water to remove all surface dirt andn dust. When all surfaces are clean, sound, wind dry, dust free and free from all surface contaminants, application of KEIM Brillantputz Rauputz may proceed.

Application
Initially use approx. 5.8 litres of water for 1 bag (25kg) and increase the amount of water until the render shows a creamy consistency, but not more than 8.5lt per bag.

Mix using a mechanical stirrer or plaster mixing machine/sprayer, e.g. Putzmeister or similar. After a waiting time of a few minutes stir again briefly. Apply the prepared KEIM Brillantputz Rauputz with a stainless-steel trowel, flatten or scrape down to grain size and rub in using a plastic trowel. To prevent streaking always work wet on wet. Always work with the same batch number in one area.

Machine Processing
KEIM Brillantputz Rauputz can be mixed using a continuous mixer. The amount of water should be adjusted according to the processing consistency. Prior to manual application, stir again briefly using a mixer to achieve the required consistency. Mortar pumps with variable flow rates are suitable for the machine application of render mixed in a continuous mixer. After application the render should be floated or scraped down to the grain size and rubbed immediately with a plastic trowel.

Application Conditions
Ambient and substrate temperature above 5°C and below 30°C. Do not apply in direct sunlight or onto sun-heated surfaces, nor if it is raining or if there is an immediate likelihood of rain.

Consumption
Rough render 2 mm: approx. 2.2 kg/m²
Rough render 3 mm: approx. 3.0 kg/m²
Rough render 5 mm: approx. 5.0 kg/m²

The stated consumption values are for guidance and depend on the nature of the substrate and the application method. Exact consumption values can only be determined by trials on the substrate.

Please Note
When using coloured mineral render, slight deviations in colour shade and irregularities can appear due to weathering which are a feature of the product. To minimise fluctuations in colour shades due to different batch numbers, the render requirement for one application should be ordered as one batch if possible.

Coating
KEIM Brillantputz Rauputz has to be coated with a single layer of KEIM Mineral Paint. Prior to coating observe a standing time of a minimum of 5 days.
