Painting company uses interior paint (StoColor Sil In) for facade painting

Hello

For 3 days our facade has been freshly painted by a company (priming, painting twice). It is a house with a facade from the 60s (location Munich), so without insulation, etc. I looked at the buckets and the company uses "StoPrim Silikat" for priming (according to the label suitable for exterior and interior) and for the coating "StoColor Sil In", which according to the label is an interior paint. I spoke to the painter (does not speak German very well) about this and he says best paint, he has been using it for 15 years, very expensive, etc.

Everything looks good so far, but what do you think about it? Can this product also be used for facade painting, does it have advantages/disadvantages? Is this known among painters even though the product sheet says otherwise? The company must have already carried out many orders with these products.

Many thanks if anyone could help me here

Just ask the manufacturer. Maybe he just made a mistake due to his poor German skills, because the color also exists without "IN".

The paint is clearly intended only for sensitive interiors. It also has a mold-inhibiting effect. So technically the absolutely wrong option. Does it work outside? No idea, but it's possible.

Hello Command, retract it, everything seems to be fine.

When I asked the painter about the buckets "StoColor Sil In" (there were many around here), it sounded to me (probably because of language difficulties) as if he was going to use the product for painting, but he only uses them for transporting tools, etc. Today I saw the correct buckets, "StoColor Sil", so an exterior paint.

yes, the good old Sto bucket...

So annoying that they always carry around their old buckets, no one can keep track anymore ... our painters have sometimes painted dispersion on the inside instead of silicate ... simply messed up completely ...
