Plaster Material Texture (Seamless-Tileable) DrCG No 89
The simple fact is that a smooth surface is, generally, a boring surface. We are creatures of detail. Tactile creatures. The rough surface of a cut stone is infinitely more pleasing that a painted plasterboard panel. That is why one of the first decorative elements to be developed for plaster as a building material was simple texturing.
Merely varying the pressure of the trowel as the surface is applied or using a variegated material can be enough to change the entire personality of a wall. But, like any decorating technique, the devil is in the details. Choosing the right texture is a much longer-term commitment than the right colour, after all.
