Protective wood treatments

[morqthana]

Shortly be getting a wooden outbuilding, and the makers recommend the following regime

1) A single coat of Cuprinol or Blackfriars, or Sadolin clear wood preservative internally and externally

2) External - they say that they've found Sadolin, Jotun/Butinox & Sikkens Novatech/Novatop to be good, but only go into detail with Sadolin, suggesting one of

- Classic then Extra
- 2 coats of Onecoat
- 2 coats of Superdec
- 2 or 3 coats of Classic

About 70 sq m external surface to cover.

Colour options, translucent/opaque and gloss/semi choices apart, does anyone have any views on one option vs another, Sadolin vs Jotun vs Sikkens?

Definitely Sadolin, we built a timber frame house ( exposed timber ) and treated the timber with Sadolin Classic. That was 42 years ago and only one re-coat applied in that time. The timbers are all still in good condition,
