Process and design scratch plaster

Scratch plaster is applied to walls in a similar way to any other plaster. The decisive difference is the final surface treatment. Depending on the desired structure, the already applied plaster is designed with a fine plaster scraper or a nail board. A smoothing trowel provides support and brushes expand the options.

Structure is created in the final top layer

Apply a fist-sized lump of plaster to the trowel with the smoothing trowel. Remove this plaster and paint it on the wall from top to bottom.
