Which wood door / window finish is right for you?
Finishes for doors and windows fall into three categories. These are
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.
