Plastering a metal garage yourself? Is it possible and what should be considered?

Good day dear house building community,

since we have received a very good offer for a galvanized sheet metal garage, I would like to know if I can simply plaster it myself afterwards?

Best regards

At least the word "einfach" you will have to omit. Plastering over the corrugations without reinforcing mesh will not be crowned with durability. You will also only be able to use few plasters at all; metal is not a good substrate. It is galvanized so that it is already durably protected. There are sand finishes in a variety of colors, so the garage also matches the house, only with the corrugated profiling retained.

Tempting prices for metal garages often result from cheap construction methods. Without insulation, a metal garage is a dripstone cave.
