Description
Gabriela Slabejová and Zuzana Vidholdová tested in 2026 how coat thickness changes the aging and mould resistance of finished beech wood. Two finishes, a solvent-based polyurethane and a water-based polyurethane-acrylate, went on mature and false-heart beech in one, two, or three layers. Boards aged indoors behind glass daylight for up to three hundred days, with color and gloss read along the way. Mould growth was scored over twenty-one days.
The solvent finish shifted color notably within a month. The water finish drifted more slowly but kept drifting. Three layers on false heartwood cut the solvent finish's color shift by near two thirds. Gloss barely moved for either finish. More layers meant less mould for both.
