Controlling appearance in Shou Sugi Ban applications

This case study shows how a parquet manufacturer stabilized surface quality and reduced rework by focusing on controlled brushing instead of reactive adjustments.

Key principles behind the achieved results

This case demonstrates how a controlled brushing approach creates stability, even in production environments with natural material variation.

Full control over texture and appearance

The wood is charred on all four sides, creating a carbonized layer that protects against weather and wear.

Controlled brushing

Brushing removes the softer charred material while preserving the harder grain, creating a strong and natural texture.

Consistent results

With the right machine setup and parameters, the process becomes repeatable and fully controllable.

The challenge

After charring the wood, the challenge was to control the final appearance. The carbonized layer defines both protection and aesthetics. Removing too much affects durability, while leaving too much limits the visual effect. The process needed to be precise, consistent, and suitable for different shapes and sizes.

The approach

A brushing solution was developed to process all four sides in a single pass. Tynex brushes were selected for their balance between strength and control. Adjustable side brushes allow for different geometries, including radiused parts. Parameters such as speed, pressure, and rotation direction can be easily adjusted and stored. An integrated dust extraction system and air knife ensure a clean surface for the next step.

The result

The customer now has full control over both the process and the final appearance. The wood shows a strong, consistent grain pattern while maintaining its protective properties. The workflow is efficient, flexible, and repeatable, perfectly suited for high-end Shou Sugi Ban applications.
