The raw material of all wooden parts is slow-growing European pine, a renewable natural resource from the well-maintained forest. Before the surface treatment process, all of the components are inspected so as to meet the criteria. The quality standard of the timber used (laminated structure, knotless on viewable surfaces) minimizes the defects of the natural material and provides a good base for any selected coat. The base coat preservative treatment is done before any colour coat or lacquer is applied. All of the products are finished with water-based paint and lacquers.
You can specify different colours, both externally to internally, this can be done for the entire project or just some items. The choice is entirely down to your own preference.
