Product Description

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 mineral substrates, both exterior and interior.

Best Uses

Keim Universal Render Fine is a renovation and thin layer exterior wall render, based on lime and silicates with a small amount of organic additives and fibre reinforcement, for use on all mineral substrates, both exterior and interior.

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.


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.

Mix in the ratio of 1kg KEIM Universal Render Fine 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 Universal Render Fine. When incorporating mesh, apply a first layer of KEIM Universal Render Fine, flatten the fabric (with an overlap of 10cm) and apply the second layer of KEIM Universal Render Fine. Finish off using a float appropriate to the required surface finish (i.e. sponge faced float such as KEIM Hydro Sponge Float).
