Which roller is best for applying plaster?

Applying the finish with a roller is especially easy when you choose the right tool for this purpose. 
The following types of rollers are recommended:

Paint rollers with polyamide fleece

Classic paint rollers are perfect for applying plaster. Polyamide fiber guarantees durability and is resistant to abrasion, making such rollers more durable. In addition, long bristles allow you to pick up more mass on the tool, which makes finishing work more efficient.

Special purpose rollers with plastic bristles dedicated for ready-mixed plasters

There are also rollers available on the market for applying plaster. Instead of traditional bristles, they have a weave of thick plastic fibers. This ensures easier removal of the plaster from the packaging and control of the amount of mass taken. The product spreads easily, is "broken up" and does not drag behind the roller. Such rollers will stay with the contractor longer because the mass does not clog the free spaces of the fleece. 
They are also easy to clean.
