Reclaimed Pitch Pine (Pino Melis): History, Conservation & Refinishing

A deep technical dive into Madrid’s most revered historic softwood: the virgin-growth longleaf pine that defined 19th-century Spanish architecture.

What is Pino Melis Viejo (Historic Pitch Pine)?

Between the mid-19th century and the 1930s, Madrid’s grandest residential estates in Chamberí, Salamanca, and Jerónimos were fitted with massive solid pine boards imported from the virgin longleaf pine forests of North America. Known in Spain as Pino Melis, this timber is distinguished by its extreme resin concentration, narrow growth rings, and exceptional hardness comparable to European oak.

Key Characteristics of Authentic Aged Melis

• Resin Crystallization: Over more than a century of natural curing, the inner resins crystallize, rendering the wood naturally resistant to wood-boring insects (woodworm) and dimensional warping.
• Amber-Honey Patina: Under natural light, authentic Melis develops a glowing reddish-amber hue that cannot be replicated by artificial stains on modern softwoods.
• High Specific Density: Unlike contemporary plantation pine, virgin pitch pine is remarkably dense and heavy.

Critical Refinishing Protocols

Restoring a hundred-year-old Melis floor requires specific expertise:

1. Low-Friction Sanding: Excessive friction softens the natural resin canals, causing clumping on abrasive belts. Controlled sanding speeds preserve the timber’s integrity.
2. Resin-Blocking Primer: Specialized barrier coats prevent resins from reacting with modern waterborne polyurethanes.
3. Anti-UV Non-Yellowing Topcoats: Using 2K waterborne polyurethanes with built-in UV filters prevents the wood from oxidizing into an undesirable harsh orange.
