Which shed paint for interior?

[PracticalTacticalBrilliance]

We've just had confirmation that our long awaited new shed can be delivered mid-December. It's coming with the outside painted thankfully but I wanted to paint the interior too before we put everything back in it.

Is this a mad thing to consider in December? Everything's already out and in the house/garden so in that sense it's the ideal time, but am worried it will be too cold.

If I can paint it, what paint would anyone recommend? Ideally I'd like a nice colour. The shed company said we could paint it & not wait for it to weather as the outside would be painted already.

Thanks for any advice!

What is it made of?

We painted the inside of ours white. It’s nice and bright.

Use a greenhouse heater to keep it warmer in there while it's drying otherwise it'll take ages

You need to read the label of the paints. They’ll have guidance about temperature because if too cold, it won’t work well (absorption, drying time, drying time between coats). As previous poster suggests, you’ll need a heater inside if you cannot meet the temperature requirements. The heater will need to be on not just while you’re in there but until paint is dry.

It's made of tongue & groove shiplap according to the site.

Good point about needing a heater, we don't have anything like that.

I think I'd use white masonry paint. Dearer than emulsion but withstands damp and can be washed down.

As your shed is uninsulated, any heat will quickly escape.

Is the concrete base exposed? Or is there a wooden floor with a ventilation gap ? (Damp will rise through concrete)

How fortuitous, I was going to ask this exact same thing.

I was going to go for white emulsion (as we have some left over). I didn't think I'd need anything fancy for a shed. 🤷🏻‍♀️

It's going to have a wooden floor & be up on bearers.

Something else I was wondering about- the old shed is rotten around the bottom. We're going to be able to put a gutter on the new shed, but is there anything else we can do to stop it happening again?

The gutter will help.

What are the bearers standing on?

The bottom of a wooden structure rots from two sources of damp:

Rain falling on the ground and splashing up (around a foot)

Water travelling up from the damp soil or base by capillary action.

The splashing will be greatly reduced by good guttering, and the rainwater being led away to a butt or drain so it does not puddle round the shed.

If there is a concrete base, you can prevent water puddling on it by having it slightly higher than the surrounding ground, with the finished footprint of the shed slightly larger than the base so rain does not fall on it. Bearers should be proteced from touching the base or ground, for example by standing them on a single course of brick with DPM on it. Airflow under the shed will then keep the shed floor reasonably dry and cold.

Thanks! The base is paving slabs at the moment. When the old shed is removed this week, they're going to check & see if anything needs doing to it before the new shed is installed.
