D20 is an essential step when applying breathable Diasen finishes over insulating plasters such as Diathonite, Argacem HP, and Argacem Ultrafine. Suitable for both interior and exterior use, D20 delivers reliable performance in new builds, retrofits, and heritage restorations, making it a versatile primer for durable, high-performance surfaces.
