CAUTION
Every eort has been made during the
manufacturing process to eliminate the
prospect of splinters on rough surfaces of the
timber. You are strongly advised to wear gloves
when working with or handling rough sawn
timber.
**Protim Aquatan T5 (621)**
Your building has been treated with Aquatan.
Aquatan is a water-based concentrate which is diluted with water, the building as been treated by the correct
application of Aquatan solution and then allowed to dry.
Aquatan is a decorative nish to colour the wood, which is applied industrially to timber fence panels and
garden buildings.
Aquatan undiluted contains: boric acid, sodium hydroxide 32% solution, aqueos mixture of sodium dioctyl
sulphosuccinat and alcohols: 2, 4, 6-trichlorophenol.

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
screwdriver, Stanley knife, Wood saw, Step ladder, Hammer and a 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 aected 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 waterproong 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 rm 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 o for water. It is also recommended that the oor be at least
25mm above the surrounding ground level to avoid ooding.
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.
