When people talk about finishes on a wooden conservatory, there are a few different things that they may be referring to. Some may be referring to the colour and type of wood used to build the conservatory, but they may also be talking about the type of treatment used to protect the wood from the weather. We’ll cover both bases for what finish is best on a wooden conservatory here.
When you’re thinking about the best wood type and finish for the conservatory, it’s best to go with a hardwood. There are both hardwoods and softwoods, and hardwoods are the most durable. Oak is the most expensive choice but is also the most durable, so lots of people decide to go for this option. Other good choices that are slightly cheaper are Brazilian cedar and idigbo. Softwoods like European redwood or Siberian larch are cheaper still, but they won’t last as long, so it may work out more cost-effective to spend more on a hardwood.
Wood is a natural material, so it’s important to look after your wooden conservatory to prevent it from rotting or getting attacked by bugs and pests. Your conservatory will be exposed to all weathers, so you’ll need to use a good finish to ensure that it stays in tip-top condition for years to come. Your installer should be able to tell you what’s best, but some of the best finishes for a wooden conservatory include breathable varnishes and decking oil. However, if you do use an oil, it’s best to use a preservative treatment too; oil will only repel water. Joints are particularly susceptible to water penetration, so make sure you use a good wood treatment and focus on areas where water would pool during rain. Then you can apply a decking oil afterwards.
