The American Black Walnut top layer is smooth sanded and sealed with UV cured natural oil. Unlike traditional parquet blocks, the Deco Parquet range of floors are engineered with a thick oak top layer with bevelled edges bonded to a hardwood ply base, which means they can be bonded to any flat surface including over low energy underfloor heating systems. Their unique sizing means they can be installed in many different patterns. ZB205 Black Walnut is also available in a matching plank.
