Raw and analyzed data for manuscript: "An open-source surface barrier discharge plasma pretreatment for reduced cracking of outdoor wood coatings"

<strong>Highlights:</strong> Surface barrier discharges are an affordable and available plasma technology for industrial, laboratory and home-workshop applications. Plasma pretreatments had no impact on the appearance of different protective wood coating for outdoor usage. The weathering performance of outdoor wood coatings improved by plasma, showing less cracks and less biotic factors.
