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

When doing plastering work yourself, the application of scratch plaster requires the final "scratching " instead of the usual smoothing.

3. Amount and swelling

Calculate the amount so that your plaster can be processed in half an hour. Let the mixed plaster swell for about five minutes and then start working quickly.

4th. Apply plaster

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.

5. Level plaster

Pull the cardade over the freshly plastered area to integrate it.

6. Structure

Let the plaster attract three to six hours. Test the condition with the scratch tool. At the circular scratching, dry "crumbs " must drop from the plaster.

7. Clean

Brushes, sweep or brush the dried scratch plaster and remove slopes remaining crumbs.
