Laser cleaning technology has emerged as a revolutionary solution for maintaining antique wooden doors and windows, offering distinct advantages over traditional methods.
Unlike abrasive mechanical techniques or chemical cleaners that risk damaging delicate wood fibers, laser systems enable non-contact, precision removal of surface contaminants through controlled light pulses.
The technology selectively ablates aged paint layers, stubborn dirt, and biological growth (moss/fungal colonization) while preserving original wood substrates and intricate carvings.
Its adjustable parameters allow operators to calibrate intensity according to material sensitivity - crucial for historic preservation projects. Environmentally superior to solvent-based approaches, it eliminates chemical waste and airborne particulates.
The process also sterilizes wood surfaces by eradicating microorganisms without moisture infiltration that causes swelling or decay.
Particularly valuable for heritage structures, laser cleaning reveals authentic patina layers for accurate restoration while maintaining structural integrity. Operational efficiency is enhanced through reduced labor intensity and repeatable results across large surface areas.
This non-invasive method minimizes maintenance downtime and extends service life, making it ideal for revitalizing architectural woodwork without compromising historical value or material authenticity.
The client is a construction company that needs to maintain old wooden doors and windows.
They want to use laser to clean off the white paint (1-2mm thickness) and then repaint. We choose hard wood, first use JEZ high-speed air-cooled laser cleaning machine to remove the surface varnish to get a rough surface(Increase the adhesion of subsequent paint), and then apply white water-based paint.
After multiple painting and air drying processes, the paint thickness reaches 1-2mm, and it is completely attached to the wood surface, then the laser cleaning test can be started.
