How to build a decorative screen

outdoor area with outdoor screens, trees and outdoor setting

Overview

Unite form and function while adding a little wow-factor into your backyard by installing a D.I.Y. decorative screen. They create a beautiful silhouette, similar to a breezeblock look, but are extremely durable and much easier to install.

The benefits don’t end there – these screens create privacy but don’t block light and still allow for airflow. They are also incredibly low-maintenance – they don’t need to be painted and will never rot or rust. The hardest part of this project will be choosing which pattern and colour to go with!

Safety tip: Always wear the appropriate safety equipment (safety glass, ear muffs, gloves and mask, for example) and always follow the instructions for the product or equipment.

Steps

1Measure and mark your space

The first thing to do is to grab your tape measure and measure your space to see how many screens you’ll need. The screens will be attached to timber posts, so measure to the inside of the post if you want to create a framed look around the screens.

2Set up string line

In this project, the design is an L shape, with three screens on one side and two on the other. Once you've determined your design, set up a string line so that you know your screens are straight. Hammer a picket at the starting point, two at the corner point (one for each post) and another at the other end point. Tie the string tightly from one point and stretch it around the centre pickets, finishing up on the other corner. Make sure the string is taut, as this will act as your guide.

3Mark your post holes

Once the string line is perfectly straight, it’s time to mark where the holes for the posts will go. Use the measurements of the screens between the posts to guide you and mark with marking paint.

4Dig the holes

It’s time to get digging! A general rule of thumb is that the depth of the post should be one-third of the height of the post above the ground. This post’s finished height is 1800mm, so the hole needs to be 600mm deep. Add an extra 100mm for gravel at the bottom. You don’t want the hole to be too wide – just enough to fit the post and gravel.

5Paint the bottom of the post

Before inserting the post, it’s a good idea to paint the part that goes in the ground with bitumen paint, as this protects the timber from rotting. Lay down a drop sheet, then measure and mark the bottom third of the post. Put on your safety equipment and use a paintbrush to apply. Wait until it dries completely.

6Paint the posts

Before installing the screens, it’s a good idea to paint or varnish the remainder of the posts in your chosen colour. Add one coat and leave to dry. Repeat with a second coat and leave to dry completely.

7Mix the concrete 

Read the instructions on your bag of concrete powder to find out the correct ratios and then grab a bucket to mix your concrete in. Add the water first, then the powder, in the right ratio. Mix it well using a stick or piece of leftover timber to a toothpaste consistency, with no dry powder spots.

If you have a wheelbarrow, you can also mix it in there; either way, make sure you’re wearing a mask, safety glasses and gloves while you mix.

8Pour the concrete

Pop each post into its corresponding hole and get ready to pour the concrete in. Before you do, double-check your post measurement is correct. Now you can go ahead and pour the concrete into each hole, filling it almost to the top.

9Brace the posts

You’ll need to ensure each post is straight. To do this, brace each one with two pieces of timber. Attach one to one side with a clamp and another piece opposite that one. These will support the post while the concrete dries overnight. Before you finish, check the post is plumb by using a spirit level on all sides. You can now remove your string guide, as well.

10Trim the posts

Measure the height of the screens and mark them on each post. Use a square to trace that mark around the post – that way, you’ll get a nice even cut. Put on your safety equipment and cut the posts to the correct height using a handsaw.

11Construct the frame

It’s time to construct the frame you'll attach the screens to. In this project, we will build the frame before we attach them to the posts. Make sure you wear the appropriate safety equipment while doing this.

If required, now’s the time to measure, cut and paint the timber of your frame, and using a drill to join it all together with screws. Along with the four pieces of timber that make up your frame, we suggest including one or two supporting beams down the middle for extra support. When measuring, allow for a few millimetres to make sure your frame fits between the posts.

12Attach your frame to the posts

Using exterior screws, attach your frame to the posts. To help keep it at the right height, chock the bottom of the frame with a piece of timber.

13Attach the screens

The final step is to attach the screens. To make installation easier, pre-drill some holes in each screen beforehand. Slide each screen to the top of the post and then screw to the frame using your drill and screws.

Add some comfy chairs, a coffee table and some pretty cushions and you’ll have a wonderful space to relax outdoors, which still lets the air flow through your space.

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.

When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
