Keim Uniputz 0.6 (Keim Universal Render Fine) is a renovation and thin layer exterior wall render, based on lime and silicates with fibre reinforcement, for use on all interior and exterior mineral substrates. Renovation and repair of sound existing renders, sound existing paint coats and for filling of cracks. Suitable for interior and exterior use. Keim Universal Render Fine can be used as a base coat for subsequent decoration using Keim Mineral Paints.

Preparation & Application

Substrate Preparation
Test substrate for load carrying capacity. Remove loose parts and old coats mechanically or with a water pressure jet. Use Keim Universal Render as a first layer for rough textured existing render or uneven substrates.

Application
Mix in the ratio of 1kg Keim Uniputz 0.6 to 0.27 - 0.29 litres of clean cold water (approximately 5.4 - 5.85 litres per 20kg bag) using a mechanical stirrer or plaster mixing machine/sprayer, e.g. Putzmeister or similar.

Do not over mix material, or re-mix material that has already set.

Apply to pre-wetted surfaces in layers from 4mm minimum to 8mm maximum. For subsequent application do not scratch up applied coat and leave for a minimum period of 12 hours before reapplication. Total thickness of render must be a minimum of 6mm.

Keim Glassfibre Reinforcing Mesh may be incorporated if required by pressing into newly applied Keim Uniputz 0.6. When incorporating mesh, apply a first layer of Keim Uniputz 0.6, flatten the fabric (with an overlap of 10cm) and apply the second layer of Keim Uniputz 0.6. 

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 Uniputz 0.6 is suitable for decoration with all exterior and interior Keim Mineral Paint systems after a minimum period of 15 days.

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.
