Description & Usage Notes
The Oast Russet Sovereign is produced using the waterstruck process, which creates a lightly textured surface and natural tonal variation. Its russet and multi colouring gives depth and warmth, fitting both restoration and character builds. With water absorption ? 21% and compressive strength ? 21 N/mm², this brick is best used for facing applications rather than heavy structural work. Its F2 frost resistance ensures durability in normal UK exposure conditions. Proper construction detailing — including cavity design, flashing, drainage, and compatible mortar — is essential for long-term performance. Always blend bricks from multiple packs to minimise colour banding, and consider building a sample panel to confirm tone and finish before committing to a large order.
