Project overview

A client asked if we could capture the feel of a “stormy sea” in plaster—movement, depth and a bold texture, not a standard smooth wall.
The project was a brick-lined stairwell that meets the kitchen in central Gothenburg. The surface had to work in everyday use, but also be a consciously designed feature that changes expression depending on light and viewing angle.
This is a strong example of how plastering can be a design material—not just a neutral finish.
Starting point
We started from exposed brick where a new plaster system needed the right adhesion and the right feel. The client wanted a lively texture with depth—but it could not become “too much”, because the wall is seen up close every day.
That’s typical for decorative plaster: the effect must be clear, but also controlled so it feels natural in the space.
The challenge
When you aim for an artistic plaster expression, it’s not enough to “add some texture”. What matters is how light moves across the surface, how depth is built up, and how irregularity is directed so the result feels intentional.
In a stairwell this matters even more, because the wall is viewed from multiple angles and in different lighting (daylight and evening lighting).
Testing and sample rounds
To hit the “stormy sea” feel we ran several sample rounds. Each round let us adjust the mix, aggregate size and how the surface was worked.
Samples matter because plaster reads very differently depending on:
- light and shadow
- viewing angle
- how much aggregate is exposed
- how the surface is closed/opened during finishing
After a few rounds we reached the right balance: strong movement and life—yet still controlled and practical for everyday use.
Materials and mix
In decorative plaster, material choice is half the result. We eventually landed on a light grey B mortar (BÖ 12) mixed with 6 mm aggregate at roughly 1:6.
That gave a coarse, durable texture with clear grain—and a surface we could shape into directional “waves”.
Note: mixes and ratios are always adapted to the substrate, environment and desired look. In this project, B mortar + 6 mm aggregate provided the right balance.
Execution: from substrate to finish
First we protected the surroundings with masking and plastic so the work could be done cleanly in a space connected to the kitchen.
We then installed reinforcement mesh on the brick and built a stable base layer. Once the base was in place, we shaped the final texture and direction.
The goal wasn’t to literally “paint water” in plaster—it was to capture the same visual energy: a coarse surface with movement that changes as you walk past.
Result
The result is a custom decorative plaster finish with a coarse texture and clear movement. In daylight and softer evening lighting, the wall reads differently—exactly as intended.
The stairwell gained a stronger identity on the way into the kitchen, and the surface feels both hand-crafted and durable in everyday use.
