To make it clear how big the price differences can be for roller plaster (€ 49.99 at Amazon *), two comparative examples are calculated below. Roll-up plaster is also suitable for do-it-yourself without any problems, so craftsmanship costs were not considered here. The comparative example relates to a room measuring 4 x 5 meters and a ceiling height of 2.60 meters - a total of around 60 square meters including the ceiling should be plastered here if door and window openings are removed.
Simple roll-on plaster from the container
In terms of price, the 20 kg container is around 35 euros, the 10 kg container around 15-20 euros. According to the manufacturer, most of these products are sufficient for around 1.5 square meters per kg, so with a small safety reserve we need 50 kg for a total price of around 90 euros. In addition, there is the necessary deep primer (€ 4.81 at Amazon *) for the surface, which must be applied beforehand. For a single coat you need around 10 liters, for a double coat, of course, twice that amount. Tiefengrund is priced between 5 and 10 euros per liter, which means you have to add between 50 and 100 euros for problem-free substrates, and between 100 and 200 euros for the deep primer for highly absorbent substrates. This means that the deep primer may even be more expensive than the roll-on plaster. Roll, squeegee and brush for the edges add up to around 20 euros if they are not already there, and around 10 euros for the necessary masking material.

Total costs therefore: at least 170 euros for this room, up to around 330 euros depending on the costs for the deep bottom. Comparative price: lime plaster in the conventional plastering process out of the sack, around 50 kg for around 40 euros, deep primer is often not necessary here.
Lime plaster as roll plaster from the professional manufacturer
The costs for the deep primer can be saved here, lime roll plaster usually makes friends with highly absorbent substrates because they even increase its durability. You have to expect significantly higher prices for the containers, but this can be worthwhile because the deep bottom is omitted: With the professional manufacturer, you can barely get there with a 20 kg container due to the greater yield, and that costs only 90 euros. In this case, the much more breathable, more ecological and high-quality lime plaster with a fine grain size is clearly the cheapest alternative among roller plasters, but conventional plaster that you can mix yourself is of course much cheaper here too.
