Shed Maintenance: How Painting Your Shed Will Help Your Shed Last Longer

Man cave, she shed or whatever you call it… you will want your shed to last a long time, and to do that you need to protect it from the elements with a bit of shed maintenance.

You should protect the wood with a splash of paint. But we’re not just talking about any old paint here. We’re talking proper wood preservative, like Sadolin, a Gillies and Mackay favourite.

With a good coat of preservative, the wood on your shed will last a lot longer than without. This video explains why treating the wood is important and why we choose to use Sadolin.

What I’m going to speak to you about today is Sadolin.

It’s a wood protection paint, a preservative, it’s something that you put on a brush and you apply to your shed.

People get a bit confused about the technicalities of what paint to use for what type of timber and all the rest of it. So, I’m going to speak to you specifically about softwood, which is what we use, and ours, in particular, is Scandinavian pine.

There are plenty of others out there, but Scandinavian pine is definitely the best type of redwood available to us.

We’re using Sadolin, which comes in a range of different specifications.

  • Superdec – which is a block colour
  • Quick Dry – which is translucent
  • Classic – which is an oil base (a more traditional type of preserving)

There are three different qualities, the UV protection, the penetrative protection and the preservative protection.

UV Protection

The UV is to do with the sun and the damage that it can cause for untreated timber.

Penetrative Protection

The penetrative protection is to do with the moisture in the air, and in Scotland, we have a lot of that. So what Sadolin tries to do is put a barrier between the outside moisture and the internal of the building.

Penetrative means that the water ingresses through from the outside to the inside. This will happen to some extent, however, if you’re using a Sadolin Superdec, it does create some form of film.

Unfortunately, timber does move, and the qualities in Sadolin Superdec means that the paint is quite flexible, but maybe not as much as it could be for our climate.

Preservative Protection

The last is the preservative protection. If you have a 19 mm thick tongue and groove Redwood weatherboard clad Scandinavian pine building like we use, you should expect that Redwood to last at least 30 years.

If you want to prolong that, you need to protect it, and to protect it you need to preserve it. That’s what you do with the paint.

The paint has a life cycle of needing to be re-treated every three to five years, and every time you do that, you’re adding to the longevity of your building.

It makes sense, make sure you’re painting your buildings with the right stuff and understanding exactly what it is that you’re doing when you’re doing it.
