Hello everyone,

I want to renovate my facade. Due to numerous plaster cracks, a full-surface reinforcing mesh will be embedded in the plaster and the facade will be painted.
I have been offered two systems:
1. The mesh is embedded using SM 700 pro, which also serves as the topcoat plaster. Finally, the facade is painted twice with silicone resin paint.
2. The mesh is embedded, then a colored topcoat plaster with a thickness of 2mm (0.08 inches) is applied.

Option 1 is about 15 percent cheaper. Does anyone have experience with method 1 or see any disadvantages?

SM700 is fiber-reinforced and quite durable. With silicone resin paint, water drains off better (dries faster) and the growth of algae or moss is inhibited. Colored plaster has the advantage that if, for example, a scratch is caused by a parked bicycle, there is almost no color difference. Both options are good; personally, I would choose option 1, but not because it is cheaper.

SM 700 or SM 700pro? This material is really good and also approved for the base area. For the topcoat, the SM 700 might be sufficient; it is also available in tinted versions.

Hm, okay, thanks for your answers. Somehow I’m still unsure about how to proceed. Are there any more opinions?

SM 700 has a noticeably finer grain compared to a render with a 2mm (0.08 inch) grain size. Depending on the color shade, fine hairline cracks can become more visible, even with reinforcement underneath. Have you seen a sample of both top coats? The appearance differs significantly, and depending on the surface area, one may be more suitable than the other.
