Surface treatment of thermally modified wood
Thermally modified wood is suitable for window-joinery, doors, garden furniture and terraces. A thermally modifi ed wood surface should always be given a high quality protective coating to preserve its beautiful colour and prevent surface cracking caused by weathering. In interiors, the dimensional stability of thermally modified wood makes it excellent for ceilings, fittings and furniture; treated surfaces are easier to keep clean.
Tikkurila has developed wood fi nishes together with the producers of thermally modified wood to achieve best performance. The warm colour of thermally modified wood is retained when the surface is treated with a wood finish/oil tinted to match the original colour. For this purpose Tikkurila has developed a specific colour (TVT 318R). We recommend making a test application.
Maintenance of Thermally Modified Wood Surfaces
Use Tikkurila Tehopesu (Super Clean) Cleaning Solution to help restore the brown colour to surfaces, which have turned grey and then apply the same products as those used for ordinary wood.
The instructions apply to new thermally modified wood surfaces. We recommend that maintenance treatment is carried out with the same type of products as were previously used for surface treatment. Exterior surfaces treated with wood oils may require annual maintenance treatment. However, maintenance should be done when necessary.
