SAFETY & MAINTENANCE
Safety precautions MUST be followed at all times throughout the construction of your building!
Care must be taken when handling
various pieces of your building since
many contain sharp edges. Please
wear work gloves, eye protection and
long sleeves when assembling or
performing any maintenance on your
building.
Practice caution with the tools being
used in the assembly of this building.
Be especially familiar with the
operation of all power tools.
Keep children and pets away from the
worksite during construction and until
the building is completely assembled.
This will help avoid distractions and
any accidents which may occur.
NEVER concentrate your weight on
the roof of the building. When using
a step ladder make sure that it is
fully open and on even ground before
climbing on it.
Do NOT attempt to assemble your
building on a windy day. The large
panels can catch the wind like a “sail”,
causing them to be whipped around
making construction difficult and
unsafe.
Do NOT attempt to assemble your
building before double checking that
you have all the parts indicated on the
parts list as well as all hardware. Any
building left partially assembled may be
seriously damaged by even light winds.
IMPORTANT NOTE ON
ANCHORING
• Your building MUST be anchored to
prevent wind damage. See anchoring
page for more info.
• You must also have a temporary
anchoring system in place in case you
need to take a break from assembly.
03GW
Exterior Care:
For a long lasting finish, clean the exterior surface. We recommend washing with a mild soap solution. DO NOT use power washing to clean
your shed.
Combustibles and corrosives must be stored in air tight containers designed for chemical and/or combustible storage. Corrosive chemicals
such as fertilizers, pesticides and herbicides should be cleaned off the interior and exterior surfaces immediately. Rust caused by chemical
damage is not covered by the warranty.
Rust protection precautions may help to stop rust from developing, or stop it quickly as soon as it appears.
• Avoid nicking or scraping the coating surface, inside and out.
• Keep roof and base perimeter free of debris and leaves which may accumulate and retain moisture. These can do double damage since
they give off acid as they decay.
• Touch up scrapes or nicks and any area of visible rust as soon as possible. Make sure the surface is free of moisture, oils, dirt or grime and
then apply an even film of high quality touch-up paint.
• Various paint manufacturers provide products for rust treatment and coverage. If surface rust does appear on your shed we recommend
treating those areas as soon as possible, following the paint supplier of your choice instructions.
• Our customer service department can provide the paint tinting formula for matching the color of your shed. We also have touch-up paint
available for repairing small nicks and scratches.
Roof: Keep the roof clear of leaves and snow. Heavy amounts of snow on the roof can damage the building making it unsafe to enter.
Fasteners: Regularly check fasteners and retighten as necessary.
General: Wash off inked part numbers on coated panels with soap and water.
Please note, Manufacturer cannot be held responsible for any consequences due to buildings that are not installed per these instructions, or
for damage due to weather conditions or acts of God.
Keep these assembly instructions and owner’s manual for future reference.

ASSEMBLY TIPS &TOOLS
How to Select and Prepare Your Building Site: Before you start to assemble your
building, you will want to decide on a good location. The best location is a level area with good drainage.
• Allow enough working space so it is not difficult to move parts into position for assembly. Also, there needs to be enough
space outside the building to be able to fasten the panel screws from the outside.
• Before assembling any parts, your base should be constructed and an anchoring system should be ready to use.
Watch the Weather Closely: Be sure the day you choose to install your building is dry and calm.
Do NOT attempt to assemble your building on a windy day. Be careful on wet or muddy ground.
Use Teamwork: Two or more people are required to assemble your building. One person can hold
the parts or panels in place while the other person fastens them together and handles the tools. This
makes the process of assembling your building faster and safer.
Tools and Materials: Here is a list of some basic tools and materials you will need to assemble
your building. Decide which method of anchoring and the type of base you will use to make a complete
list of the materials you will need.
• Work Gloves
• Safety Glasses
• Nut Driver or Wrench
• Step Ladder 8’
• Power Drill (Cordless, Variable Speed)
• Pliers
• Utility Knife or Scissors
• Carpenter’s Level
• Tape Measure
• Clamp
• Spray Lubricant
• Square
• String (for squaring the frame)
• Awl (to align holes)
• Lumber and/or Concrete
• Hammer and Nails
• Spade or Shovel
• Hand Saw or Power Saw

WHAT YOU NEED

Base
05GW
The Base For Your Building
Concrete Slab
The slab should be at least 4" (10,2 cm) thick. It must be level and flat to provide good support for the frame.
The following are the recommended materials for your base.
2 x 4's (38 mm x 89 mm) (will be removed once the concrete cures)
Concrete Sheet of 6 mil plastic
We recommend for a proper strength concrete to use a mix of:
1 part cement 3 parts pea sized gravel 2 1/2 parts clean sand
Prepare the Site/Construct a Base
1. Dig a square, 6" (15,2 cm) deep into the ground (remove grass).
2. Fill up to 4" (10,2 cm) in the square with gravel and tamp fi rm.
3. Cover gravel with a sheet of 6 mil plastic.
4. Construct a wood frame using four planks of 2x4 (38 mm x 89 mm)
lumber.
5. Pour in concrete to fi ll in the hole and the frame giving a
total of 4" (10,2 cm) thick concrete. Be sure surface is level.
Allow 3 - 5 hours for construction and a week for concrete curing time.
Note: Before beginning construction, check local building codes
regarding footings, location and other requirements.

It is important that the entire floor frame be anchored after the building is erected.
Below are recommended ways of anchoring.
Anchoring Down The Building
Anchoring into Concrete:
For poured concrete slab or footing or patio blocks:
Use 1/4" x 2" (6 mm x 51 mm) Lag Screws.
Anchoring into Wood:
Use 1/4" (6 mm) Wood Screws. There are 1/4" (6 mm)
dia. holes provided in the frames for proper anchoring.
