By hardening the wood, our floors become up to three times more resistant to impact than traditional parquet flooring. This helps prevent deep dents caused by dropped objects.
However, wood floors can still be scratched. Scratches typically affect only the surface finish and can often be concealed through regular maintenance. To maintain the appearance and durability of your wood floor over time, it is important to care for it properly. Avoid dragging heavy furniture across the floor, and make sure to regularly vacuum away dirt and grit, as these can cause wear.
If the floor becomes damaged and needs repair, this can be done by filling the damaged area with wood filler or simply replacing the affected plank. Instructions on how to do this can be found here.
Hardness is measured using the Brinell scale. This is a method of measuring a material’s hardness, developed by Johan August Brinell. Brinell hardness is determined by pressing a hardened steel ball, 10 mm in diameter, into the material with a set force (typically 3000 N) for a specific period of time. The size of the resulting indentation is then measured and converted into a value. The higher the value, the harder the floor.
Brinell hardness for different wood species:
Hardened wood: 8–10
Jatoba: 7
Ash: 4.0
Birch: 3.8
Oak: 3.7
Walnut: 3.4
Pine: 1.6
Spruce: 1.4
Brinell hardness measures resistance to indentation, not scratch resistance. While Bjelin’s Woodura floors achieve an excellent Brinell rating, it is still possible to scratch the lacquered surface. However, any indentations will be significantly smaller compared with traditional wood flooring under the same force.
