Surface properties of thermally modified wood floorings

Thermally modified wood (TMW) surfaces appear very attractive and are therefore ever more frequently used in floorings. Positive changes of properties as a result of thermal modification like improved dimensional stability, reduced equilibrium moisture content, reduced water vapour and liquid water permeability are frequently used as an important argument for application of these products in everyday life. In order to protect and maintain their initial appearance wood floors are regularly surface finished. Most often used finishes in floor coverings include UV curing varnishes, combinations of oils and waxes, and classic solvent borne and water borne varnishes. The aim of this work was to examine the influence of the substrate as well as efficiency of coating material to surface properties of TMW. For the experimental purposes samples were prepared to form the following variables: wood species (oak, beech and ash), modification process (unmodified and TMW), as well as finishing system (uncoated, UV varnish, oil, UV oil). Material for testing was commercially heat treated for a local parquet manufacturer at 210°C in water vapour atmosphere. Laboratory tests implied film thickness measurements, scratch resistance, slip resistance and resistance to chemical agents. Results bring relations of all tested variables to surface resistance of TMW. Generally, surfaces protected with UV curing varnish exhibit better properties. Still, both UV curing oil and oxidative oil which form a thin protective layer of 18 to 22 µm, showed very good resistance to chemical agents and slip resistance. Despite the fact that UV oil and oxidative oil exhibited similar results on wood flooring elements, a question that remains is how to ensure regular maintenance and repair of these products.
