This statue showed a significant build-up of dirt and surface contamination caused by prolonged exposure to outdoor conditions. Over time, the stone surface had become affected by dark deposits, organic matter and other contaminants that altered its appearance and made the sculpture’s finer details less visible.
The Process
The cleaning was then performed gradually and under controlled conditions, directing the laser only at the areas requiring treatment. The applied laser energy removes surface contaminants without the use of chemicals, water or abrasive materials.
A limpeza foi depois realizada de forma progressiva e controlada, direcionando o laser apenas para as zonas a tratar. A energia aplicada permite remover os contaminantes presentes à superfície sem recorrer a produtos químicos, água ou materiais abrasivos.
Throughout the process, the parameters are adjusted according to the response of the surface, allowing delicate areas, reliefs and intricate details of the sculpture to be treated with greater precision.
The Result
Removing the layer of contamination helped restore the stone’s original appearance and reveal details that had previously been partially obscured.
The result clearly shows the difference between the surface before and after treatment, while preserving the geometry, texture and decorative details of the piece.
For this type of application, laser cleaning provides a precise and controlled approach, particularly when contaminants need to be removed without resorting to more aggressive cleaning methods.
