Façades  

Substrate has to be hard, dry, free of dust, grease and other impurities, and all preliminary works on façade surfaces have to be completed (installation of sills, mounting of gutter brackets, mounting of air-conditioner brackets and similar). Cement and cement-lime mortars should dry for at least 1 day for each mm of thickness.

(T=20°C, rel.humidity 65%), and concrete surfaces should dry for at least one month. Uneven surfaces should be levelled. Hot water jet or steam wash is recommended to perform additional cleaning. Surfaces contaminated with algae and fungi should be remediated before the façade is applied. (treat the entire wall surface with ALGOSTOP, not only the spots with algae and fungi).

24 hours before applying FASSADE SILIKAT, apply the PODLOGA UNIVERSAL primer of approximately the same colour as the colour of the façade on the wall. PODLOGA KVARC product is recommended for extremely smooth surface. The primers represent, at the same, time a bridge binding the substrate and the applied material, creating a stronger bond and reducing consumption of material.

Before application, mix the compound thoroughly with an electric mixer in the container. The same shades (including white) from different production batches may differ due to natural origins of used raw material.

In case of large surfaces, equalizing should be done in a container big enough to avoid non-uniformity of shade (quantity of façade needed for the total surface should be ordered at once rather than to make partial orders).

No diluting or adding of toners for tinting should be done during the application of material. Works should be performed without interruptions and as fast as possible, from one wall end to another. In case of multi-storey buildings, façade is applied without interruptions on one side of the building, starting from the top stories down to the lower ones.

Application is performed using stainless metal trowel evenly in the thickness of the largest grain. After several minutes (depending on the wall absorption and air temperature), the façade surface should be scratch coated using a plastic trowel, circularly, until an even structure is achieved.

Optimal air and wall temperatures during application and drying should be from +10°C up to +25°C, and relative humidity should be under 80%. Use protective sheeting for scaffolds during application. Do not work in wind, rain, fog or in direct sun. Wash tools with water immediately after use.
