With our wide range of colours there is something for everyone, from calming grey tones to pop colours.
Please note: We've made every effort to make the colours appearing on screen as close as possible to the ones applied by us. Unfortunately, we cannot guarantee an exact colour match of the screen colour and the building colour.




What is the ready painted service?
Our ready painted service is available on a range of our shiplap sheds, summerhouses, greenhouses, playhouses and insulated garden rooms. We use premium, fully opaque paint that offers exceptional durability with a low maintenance finish. The paint will act as a preservative to protect against weathering, UV degradation, mould and fungal attack.
Choose your favourite colour from our wide range of shades from neutral tones to popping brights! Your painted garden building will have a stylish and eye-catching look, with the highest quality finish!

What are the benefits?
- Installation is included!
- The building will arrive finished to the highest standard and protected from the get go
- Cuts out the hassle and saves customers valuable time!
- Customers will receive an additional 1L tin of paint for touch ups
- We offer a wide range of colour options
- The building will benefit from our Paint Promise guarantee*. This means the paint will last 3 years with minor care and attention - and the building will still benefit from our 10 year anti rot guarantee!

Our painting process
Our four stage painting process has been developed to ensure your
garden building is finished to the highest standard.


Step 1 End Grain Sealer
We apply a water based barrier coat which penetrates and seals porous end grain, reducing moisture uptake by up to 90%.

Step 2 Primer
We then use a water based isolating paint as primer to minimise yellowing from knots and softwood with a large amount of heartwood.

Step 3 Paint
AQUATOP®, our fully opaque topcoat, provides extended protection against weathering, UV degradation, mould and fungal attack. Proprietary technology minimises micro foaming in the final paint finish, extending the coating durability.

Step 4 Touch Up
We touch-up any blemishes onsite during installation. Additional paint is supplied with the building on handover for any future touch-ups.
*Paint Promise Guarantee - In most circumstances the paint we apply to your building will give the building up to 3 years without needing another coat or retreating. In exposed and coastal locations and on open elevations, wind, rain and strong sunlight can cause more rapid degradation of the protective film, therefor affecting the integrity of the paint.
