Good day welcome to MakeStuff4U. I am a local artisan with now 40 years experience. These panels are extremely well made all components are pre-washed before assembly. Basically these panels can last generations by re-washing once every 10 years or so. Basically you wipe the paint on let it sit for a moment and wipe it off. The paint soaks into the wood and when you wipe off access, there’s nothing left on the surface to disintegrate over the years. Take a moment to view my past projects, then drop me a line for a quote.
