Appearance & Coatings



Once installed, timber windows should be coated to protect/retain appearance or to ensure the ongoing durability of the material.

Both interior and exterior timber window surfaces are easily and satisfactorily coated with a wide range of protective products such as:

  • paints – acrylic and solvent-based;
  • stains; or
  • oils.

For interior surfaces, protection is generally a straightforward process. Particularly, as the timber used is normally seasoned and free of surface impurities that may hamper the coating process.

Exterior timber surfaces on the other hand are exposed to the elements of ultraviolet light, heat, cold, water and airborne contaminates before and during coating. These elements can create difficulties for the painter.

The purpose of an exterior coating is firstly to provide a protective coating against these elements, called weathering, and secondly to provide an appealing overall finish to the structure.

The selection of the correct coating product is essential to maintain visual appeal and also for the ongoing performance of the timber.

Each timber species has particular characteristics that could effect the application of certain products. Therefore, it is important to know a little about the timber being coated and make reference to the various manufacturers’ product literature for specific recommendations.
