What To Paint My Summerhouse With

Ask a Professional: I’m Wondering What To Paint My Summerhouse With

So, you have your brand new summerhouse and it is looking glorious out in your garden but you feel it needs that something extra. Ahh, yes, a lick of paint! A summerhouse can be seemingly transformed with colour, it’s just a case of deciding what colours to opt for, what designs you like and what to paint it with. 

An outdoor structure needs to last you and protecting it with the right paint or varnish is crucial in ensuring that this happens. Not only will it help it to look good it will also waterproof it against the wonderful British weather and prevent it from developing damp. With so many products on the market, it can be easy to feel overwhelmed by the options, jargon, promises and ease of use so we are here to help you.


The first and most important thing to look for in outdoor paint is that it is an all-weather paint. To prevent you from having to re-touch it, to prevent disappoint as it fades, you want durability. The best on the market include:

  • Culprinol which comes in a wide range of colours and is very hardy.
  • Dulux which is available in a weathershield option and also comes with a guarantee (no flaking, mould or peeling).
  • Ronseal does exactly what it says on the tin! Their aim is to make DIY simple for anybody to achieve.
  • Johnstones Woodcare and Johnstone’s Weatherguard lines cover everything from undercoats, gloss, and masonry to varnishes, stains, oils, and colours for the outside.

Before you begin to even think about painting do you research on the look you are wanting to achieve. Pinterest has some amazing images for this and you can easily get lost down an inspirations rabbit hole. The key thing is that it has to be right. You do not want to be applying colour and end up not liking it. This type of paint won’t be easily removed – if at all – and covering it will take a lot more paint and expense. If you know which brand you are leaning towards using, check their colour range first and then begin to make that Pinterest board! If you have a piece of leftover wood or a few planks of them, apply your favoured colours to these using tester pots just to check how the colour goes on, how much you think you will need (2 coats is usually average) and also that it comes out as it says on the tin. We all know that it often doesn’t! Your colour scheme will also need to tie in nicely with the overall look of your garden and also with the interior of your summerhouse.


If you like the natural look of the wood on your summerhouse, a really simple way of keeping this is by varnishing the outside rather than painting it. A natural wood varnish will protect it but maintain that gorgeous rich look which will last you for years.

Gain Advice

If you want to make absolutely sure that you’re making the right choice in summerhouse paint, you should gain independent advice from a store such as Brewers. They are the go-to store for professional decorators and they can advise without any bias. They will discuss the look you are after, the location of your summerhouse, what this will mean in terms of which paint you opt for and they can even mix it for you right there in store. Yes, this may turn out to be a more pricey option but you will save money in the long-term.

Environmentally Friendly

With more and more people becoming far more eco-conscious it is understandable that they don’t want to be painting their summerhouse with a product that is full of toxins which may be harmful to the wildlife or ground. Traditionally, paints and treatments for outdoor wood were mostly solvent-based, but this is no longer your only option. Water-based paints have been further developed to ensure that they are more durable for outdoor use. Not only is this better for your garden, it is also kinder to your brushes as well as your skin.

Time Frame

Most garden rooms/shed/summerhouse manufacturers will advise that you paint and protect your new building within 3 months. This is because they will come with a warranty and if water gets in, that warranty could be void. Thankfully, the wood will be all ready to go and there will be no prep required of it so all you will need to do is choose a colour scheme and a good day to get it done.
