Can I apply Yosima Clay Plaster on wood-based materials such as MDF or chipboard?
YOSIMA clay plaster can be applied to wood-based materials. However, before applying a plaster primer containing quartz, the wood-based material must be blocked against the so-called "bleed-through" of wood constituents. This would later lead to undesirable discoloration of the clay plaster. Solvent-based primers such as Brillux Adhesion Primer are suitable for blocking. It should be noted that joints of wood-based materials cannot be reinforced like plasterboard joints. Instead, the joints of the wood-based materials must be force-locked and glued. Simply gluing is not sufficient.
