TEKA Parquet has divided most of its wood species in up to 4 different gradings because wood is always changing its appearance from tree to tree.
TEKA divides the visual appearance of the wood into:
classic still homogeneous but already with a bit more contrast and smaller, scattered knots
natural the middle grading with contrast and sound knots and the wildest grading
active with strong contrast and knots unlimited in size and number also putty filled in matching colour.
