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 treat-
ment 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.
Whilst all products manufactured are made to the highest standards of Safety and in the case of childrens
products independently tested to EN71 level, we cannot accept responsibility for your safety whilst erecting or
using this product.
Refer to the instructions pages for your specific product code
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.
