The base must be undamaged, clean, and damp enough to be darker in colour. There must be no cement paste on the surface. If necessary, water sand blast and pressure wash the surfaces. Begin wetting the base on the previous day. The required amount of wetting depends on the weather conditions and, for instance, the strength of the base. Bases with a high strength require more wetting. You must always ensure that there is no standing water on the base when starting rendering. 


Total water requirement is around 3.6 l/25 kg of dry product. Add the dry material to the water and mix with a power mixer for around one to two minutes allow to stand for five minutes and mix again for a short while. Find the final consistency at this stage by adding water when necessary. However, keep the total amount of water at around 14,4% of the dry product. The finished plaster remains workable for around one hour.

Work instructions

Take particular care during manual application. In machine application, use sufficiently powerful pumping equipment to apply the compound, for example, a plastering pump. If necessary, test to ensure that the equipment is suitable. The recommended layer thickness for a single spraying is 2-4 mm. You can use thicker fills when patching individual cavities. The lowest working temperature is +5 C. Nor should the temperature be allowed to fall below this during aftercare. The aftercare must be begun immediately after the plaster has been spread and must continue for at least five days. We recommend plastic covers and a hood. The aftercare is stopped in stages. Naturally, the SILKO guidelines shall also be followed during aftercare.
