General Instructions

BEFORE YOU START PLEASE READ INSTRUCTIONS CAREFULLY 

- Check the pack and make sure you have all the parts listed. 

- When you are ready to start, make sure you have the right tools at hand (not supplied) including  a Phillips screw-

driver, Stanley knife, wood saw, step ladder and drill with 2mm bit.

- Ensure there is plenty of space and a clean dry area for assembly. 

TIMBER

As with all natural materials, timber can be affected during various weather conditions. For the duration of heavy or 

extended periods of rain, swelling of the wood panels may occur. Warping of the wood may also occur during 

excessive dry spells due to an interior moisture loss. Unfortunately, these processes cannot be avoided but can be 

helped. It is suggested that the outdoor building is sprayed with water during extended periods of warm sunshine 

and sheltered as much as possible during rain or snow. 

Once your garden building has been installed it will need to be treated as soon as possible and annually to prevent 

the timber from deteriorating and to waterproof it. This is required to maintain the anti-rot guarantee. 

Dip Treated buildings - Require a preservative treatment to protect against rot and decay and a waterproof treatment 

to prevent water ingress

Pressure Treated buildings - Require a waterproof treatment to prevent water ingress

Log Cabins - Are supplied untreated and require a preservative and waterproofing treatment.

BUILDING A BASE

When thinking about where the building and base is going to be constructed: 

Ensure that there will be access to all sides for maintenance work and annual 

treatment.

Ensure the base is level and is built on firm ground, to prevent distortion.  Refer to diagrams for the base dimensions,  

The base should be slightly smaller than the external measurement of the building, i.e. The cladding should overlap 

the base, creating a run off for water. It is also recommended that the floor be at least 25mm above the surrounding 

ground level to avoid flooding.

TYPES OF BASE

- Concrete 75mm laid on top of 75mm hard-core.

- Slabs laid on 50mm of sharp sand.

Pressure Treated Timber

Pressure treating is a chemical process which helps to protect wood against adverse weather which could 

lead to rot or insect damage.

The most common chemicals used to pressure treat wood are 

Alkaline Copper Quaternary

 (

ACQ

), 

Copper Azole

 (

CA

), and 

Micronized Copper Quaternary

 (

MCQ

).

Safety: 

Always wear gloves, eye protection and a dust mask when handling wood. Due to chemicals in 

pressure treated wood, never burn its sawdust or scraps; instead dispose in a landfill.
