How to apply rough plaster expertly

A beautifully structured rough plaster is a timeless adornment for every wall, it can be painted white or colored and lasts for decades. How do you apply your roughing and how does it get its structure?

The right substrate for roughing

First check the surface before applying your roughcast. Only a clean, smooth surface gives enough grip and prevents damage. Remove old wallpaper and paint residues as well as loose plaster thoroughly. Holes should be closed with a suitable filler. Window and door frames protect you from stains by masking them with masking tape. You should also cover the floor thoroughly - a board, for example a scaffold board, is especially useful for this. Prime your wall surface with a suitable primer before applying the roughcast: A dispersion-based primer is suitable for the subsequent application of a synthetic resin plaster, while a mineral plaster lasts particularly well on a silicate primer. Ra Apply rough plaster with the trowel

Before applying, you must mix your rough plaster according to the processing instructions; The goal is a creamy, not too liquid consistency. Do not use more material than you can put on the wall in about 20 minutes. Apply the plaster with the trowel by placing the trowel steeply against the wall and peeling the material down to grain thickness. Start at the bottom of the wall and work your way up. After about 15 minutes of drying time, structure the applied rough plaster with the help of the rubbing board.

Working roughcast with the floater

Floating boards for structuring rough plaster consist of either wood or plastic. Lay the board flat on the applied plaster and move it with light pressure. Choose between circular, vertical, horizontal or diagonal movements and pay attention to the uniformity of the resulting structure. Of course, you can also try your pattern on a practice surface first
