- Just a thought please. Why? Once the paint is on, you won’t notice any difference of the expensive stuff in your house. You go into a house with gypsum plaster and then think: phew, there’s no difference. And all that money for nothing.
Lime plasters make sense in the area of monument preservation. Let’s say a castle or a church is to be renovated. Late Middle Ages. The builders back then couldn’t build airtight. It wasn’t possible. They didn’t have the material yet. The Romans knew about concrete, but that had been forgotten in Northern Europe in the meantime.
If you now coat such a wall from the inside with machine plaster and paint it with Caparol, the following happens: from the outside, the wall absorbs water during damp weather periods. Inside it’s sealed off. This causes the water to make the plaster flake off. Typical damage due to old meeting modern. If you take lime plaster and chalk paint, plaster and paint become slightly damp but don’t flake off. Then drier weather or wind comes, and the wall dries out, the plaster too, the paint too, nothing happens.
Clear? But your house is sealed on the outside and dry on the inside. So what’s the use of this plaster? Ask yourself that very objectively. K.
