Preparation & Application


Substrate Preparation
Test substrate for load carrying capacity. Remove loose parts and old coats mechanically or with a water pressure jet.

Application
Mix in the ratio of 1kg Keim Universal Render to 0.24 litres of clean cold water (approximately 6 litres per 25kg bag) using a mechanical stirrer or plaster mixing machine/sprayer, e.g. Putzmeister or similar.

Apply to pre-wetted surfaces in layers from 4mm minimum to 10mm maximum. For subsequent applications do not scratch up between coats and leave for a minimum period of at least 12 hours between coats.

Keim Glassfibre Reinforcing Mesh may be incorporated, if required, by pressing into newly applied Keim Universal Render. When incorporating mesh, apply a first layer of Keim Universal Render, flatten the fabric (with an overlap of 10cm) and apply the second layer of Keim Universal Render.

Finish off using a float appropriate to the required surface finish (i.e. sponge faced float such as KEIM Hydro Sponge Float).

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. Setting Time 1 day per 1mm render layer thickness.

Subsequent Finishing
KEIM Universal Render is suitable for decoration with all exterior and interior Keim Mineral Paint systems after a minimum period of 15 days. For finishing with Keim Brillantputz, no preparatory work is necessary.

Consumption
Approximately 1.1kg/m² per 1mm render layer thickness.

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.

Cleaning of Tools
Clean tools with water immediately after use.
