Which wood door / window finish is right for you?

Finishes for doors and windows fall into three categories.  These are

  • Penetrating finishes (such as Danish oil or Teak oil)
  • Semi-penetrating finishes (such as OSMO UV Protection Oil or Sikkens HLS)  or
  • Varnishes (such as Sikkens Filter 7 or Sadolin Clear Coat).

Each give differing degrees of protection.  Varnishes offer the longest maintenance-free treatment but when they do fail, they can flake and so will need removing.  For this reason, semi-penetrating finishes are popular as they offer some protection but are easy to repair.

In addition, finishes may be clear, translucent or opaque and in different sheens – usually satin or satin-matt.

It is difficult to treat exterior wood with a clear finish and (long term), keep its full natural colour but you can slow it down by using a product that contains a UV inhibitor.  We have had good success with OSMO UV Protection Oil on oak as long as it is retreated from time to time.  Opaque colours (solid colour) offer the most protection -  Osmo Country Colour is easily retreatable usually lasting up to 2 to 4 years.  Jotun Demidekk Opaque Wood Stain when used with Visir Primer can offer 8 to 12 years under normal conditions.

So, remember…
