Sioo:x Wood Protection gives outdoor wood surfaces a beautiful, natural silver-grey hue and keeps them protected for twelve years. It’s also 100% environmentally friendly – which is revolutionary.

But twelve years’ worth of protection is almost too good to be true. Our mission was to prove it is for real. So we created a billboard made from real Sioo:x-treated boards and booked a triple-sided billboard for twelve years in Malmö, Sweden.
