Walnut Natural Unsealed 180 x 20 mm

Engineered Flooring 180 mm x 20 mm

This product is unsealed, giving you the opportunity to finish it as you like, using an oil to retain the warmer tones and characteristics of Walnut, or a lacquer to enhance the wood’s natural hues.

Sourced from safely managed forests in Northern America, Walnut is a popular species that adds character to any room with its rich and luxurious appeal. Walnut is a beautiful dark and intense brown hardwood with a high-end look. This species is rich in detail and its warm tones are sure to bring a room to life.

Engineered wood floors are suitable for kitchens, bathrooms, utility rooms, and any other room in the house because of their greater stability and lower moisture level in the wood.
We recommend adding 7-10% m2 to the total area for board or strip floors, or 10-15% for parquet.
