Painting your summerhouse or garden buildings can be a fun and rewarding DIY project, but picking the right paint can make all the difference to the final result. The paint you choose needs to not only provide an attractive finish to your summerhouse but also protect the wood from the elements for years to come.

One of the most critical factors to consider with exterior wood paints is the type that you use. Oil-based paints are known for their durability and ability to repel water, but they can take longer to dry and emit strong odours. On the other hand, water-based paints dry faster and have lower VOC emissions, but they may not be as durable.

Another important consideration is the colour. Lighter colours reflect heat and sunlight, which can help the summerhouse stay cooler during hot summer days. Whereas darker colours absorb heat and may cause the wood to expand and contract leading to cracking and peeling.

Buying Guide

As you can see from our wood paints reviews, there are various factors to consider when choosing the best paint for your summerhouse. Here is a rundown of what to keep in mind:


You want a paint that can withstand the harsh summer weather conditions, including high temperatures, UV rays, and rain.

Look for a paint that is specifically designed for outdoor use and has a reputation for even coverage and longevity.


The colour you choose is not only an aesthetic consideration but can also affect the temperature inside your summerhouse.

Darker colours tend to absorb more heat, while lighter colours reflect it. If you live in a hot climate, you may want to go with a lighter colour to keep your summerhouse cooler and more comfortable.

Ease of Application

Some paints are easier to apply than others, so consider how much time and effort you are willing to put into the painting process itself. Certain paints also require multiple coats, while others can be applied in one.

This means that you have to weigh the cost against how much you will need for full coverage.

Type of Paint

There are several types of paint to choose from, including oil-based, water-based, and latex. Each type has its advantages and disadvantages.

Oil-based paints tend to be more durable but can take longer to dry, whereas water-based and latex paints are easier to clean up but may not be as hardy over the long term.

Other considerations are whether the paint is flexible, waterproof or fade-resistant.


The price of outdoor paint can vary widely depending on the brand and type. Consider your budget and how much you are willing to spend.

Keep in mind that a higher-priced paint may be more durable, take less coats and last longer. This could potentially save you money in the long run.

Frequently Asked Questions

What are some popular brands for painting a summerhouse?

When it comes to painting a summerhouse, there are many brands to choose from. Some popular brands include Dulux, Cuprinol, Ronseal and Johnstone's among others.

What type of paint is best for a summerhouse?

The best type of paint for a summerhouse is an exterior paint that is specifically designed for outdoor use. These paints are formulated to withstand the elements and protect your summerhouse from sun, rain, and wind damage.

Look for a paint that is water-resistant, fade-resistant, and has a high level of UV protection or is UV resistant.

Can I use outdoor paint for my summerhouse?

Yes, outdoor paint is the best option for painting your summerhouse. It is specifically formulated to withstand all weathers, protecting your summerhouse from UV rays, heavy rain, and wind damage.

Using indoor paint can cause the exterior surfaces of your summerhouse to peel, crack, and fade quickly.

Are there any specific colours that work well for summerhouse paint?

When it comes to summerhouse paint colours, light and bright colours work best. Light colours reflect heat and sunlight, keeping your summerhouse cool during the summer months, whereas bright colours add a pop of colour to your garden, making your summerhouse stand out.

Some popular summerhouse colours include white, light blue, light green, and yellow.

Should I use a primer before painting my summerhouse?

Using a primer before painting your summerhouse can help the paint adhere better and ultimately last longer. A primer can also help cover any stains or marks on your summer house before adding the final coat.

Some outdoor paints are self-priming and do not require a primer, therefore can simply be painted directly onto the existing surface. However, if you do use one, make sure that is specifically designed for outdoor use and that is compatible with your chosen paint and any previously painted surfaces.

Is it necessary to use a sealant after painting a summerhouse?

Sealing the finished coat of paint on your summerhouse can help give enhanced protection from fading and peeling. A sealant can also help protect the summer house from water damage and UV rays.

However, it is not a requirement, as many modern garden paints are formulated to deal with these issues without the need for extra protection.
