Step 1 Planning Materials
- Posts 100 x 100mm x 1.8m H4 treated rough sawn
- Palings 150 x 19 H3.2 treated rough sawn OR 150 x 25 H3.2
- Rails 75 x 50mm x 4.8m H3.2 treated rough sawn OR 100 x 50mm x 4.8m H3.2 treated
- Concrete (either builders mix and cement at a ratio of 6: 1, pre-mixed easy set)
- Galvanised 100mm flat head
nails (to fix rails)
- Galvanised fencing nails
annular groove 500g 60mm
- Coach screws (for attaching
rails to posts in high wind
- Baton purlin screws 100mm
- Concrete blocks for the
bottom of holes
Step 2 Fencing Layout/Dig Holes
- Decide your height and choose your posts to suit.
- Use 100mm x 100mm h4 treated rough sawn.
- Space them 2m apart.
- Dig holes with a spade or post hole borer to a depth of 600mm.
- Clear out any loose material in the holes
Step 3 Brace The Posts
- Move your stringline from the centre of the post holes, to
50mm away from where the face of your posts will sit.
- Then position every post 50mm off the string line, which will be straight.
- Once you are happy with the placement of the posts you can
continue to the next step
Step 4 Concrete Posts
- Next, measure up and draw yourself a plan,
then work out your materials and order them.
- Mix concrete as per instructions on the bag.
Pour the concrete around the posts carefully.
- After 24 hours the braces can be removed.
Step 5 Fence Rails
Rails J Mark the position of the rails on your
posts with a chalk line.
Keep rails 150mm up from the bottom and
150mm down from the top.
Use two rails for fences up to 1200mm high.
Use three rails for fence heights above
1200mm. Use 100 x 50mm H3.2 treated
rails, and for spans under 1.8m use 75 x
50mm H3.2 treated rails.
If your ground is uneven, find the highest
point and measure up the post from that
point for your bottom rail.
Rails can be fixed either between the posts or
to the face of the post depending on fence
Step 6 Palings/Final Touches
Fix palings to rails with galvanised fencing
nails. Our boards are 25mm thick, so we’re
using 75mm nails. Use 2 nails in each rail so
that’s 6 nails per paling. Place them 25mm
from each side.
Place a paling on the ground and sit your
palings on top of the board. This will help
you keep them from touching the ground
Push the palings tightly together as you nail
them, as they will shrink. Use a hammer and
chisel to force the boards as close together
as you can.
Cut palings to height. Flick a chalk
line as a guide and use a circular saw.
It’s a good idea to screw a board to
the fence to use as a guide, this will
give you a nice straight line.
Cut tops off posts on a slight angle
using a handsaw. This helps the water
drain off the post
