When sourcing white wash cabinets, the base material significantly impacts the final aesthetic. Solid wood (such as Paulownia, Pine, or Oak) is preferred for an authentic rustic look as it allows the natural grain to show through the translucent stain. For budget-friendly options, MDF with a wood veneer can be used, but ensure the veneer thickness is at least 0.6mm to prevent peeling. The 'white wash' effect should be achieved using water-based, eco-friendly paints that meet EN71-3 or ASTM D4236 standards to ensure low VOC emissions.
