How to Install a Magnetic Fly Screen
Installing a magnetic fly screen takes about 15-30 minutes and requires minimal tools. The screen attaches to your door frame using adhesive strips or pins, creating a hands-free entry point that closes automatically behind you while keeping insects out.

Tools and Materials You'll Need
Before starting your installation, gather these basic supplies:
- Magnetic fly screen kit (includes screen panels and fastening strips)
- Measuring tape
- Scissors or utility knife
- Cleaning cloth and methylated spirits
- Ladder or step stool (for taller doorways)
- Pencil for marking (optional)
Most quality magnetic fly screens come with everything needed for installation. Check your kit includes the mesh panels, magnetic strips down the centre, and either adhesive backing or thumbtacks for mounting.
Choosing the Right Screen Size
Measure your door frame's height and width before purchasing. Standard Australian doors are typically 2040mm x 820mm, but verify your measurements. Most magnetic screens accommodate frames up to 2100mm x 1000mm and can be trimmed to fit smaller openings.
Preparing Your Door Frame
Proper preparation ensures your magnetic fly screen stays securely attached throughout the season.
Clean the Surface
Wipe down your door frame thoroughly with methylated spirits or a degreasing cleaner. Remove dust, cobwebs, and any oily residue that could prevent the adhesive from bonding properly. Let the surface dry completely—this usually takes 5-10 minutes.
Check for Damage
Inspect your door frame for peeling paint, cracks, or rough spots. Sand down any rough areas and ensure the surface is smooth. If paint is flaking, consider touching it up before installation, as the adhesive works best on intact surfaces.
Mark Your Placement
Hold the screen up to your doorway to visualise the final position. The screen should sit flush with the outer edge of your door frame, covering the entire opening with a small overlap. Mark the top corners lightly with a pencil if needed.
Installing the Magnetic Fly Screen
Follow these steps for a secure, long-lasting installation:
Step 1: Attach the Top Edge
Start at the top of your door frame. Peel back 10-15cm of the adhesive backing and press the screen firmly against the frame, working from one corner across. Smooth out any bubbles or wrinkles as you go. This top edge is crucial—it bears the weight of the entire screen.
Step 2: Secure the Sides
Once the top is firmly attached, work down each side. Peel the adhesive backing gradually, pressing the screen against the frame in 20-30cm sections. Keep the screen taut but not stretched, ensuring the magnetic centre seam hangs straight.
Step 3: Attach the Bottom
Finish by securing the bottom edge. The screen should just touch your threshold or floor without bunching. If it's too long, trim the excess with scissors before removing the final adhesive backing.
Step 4: Reinforce High-Traffic Areas
For added security, especially around doors that see frequent use, add extra thumbtacks or small nails through the reinforced edges. Place them every 30-40cm along the frame.
Testing and Adjusting Your Screen
After installation, test the magnetic closure by walking through several times. The two centre panels should separate easily and snap back together automatically. If they don't align properly, you may need to adjust the screen's position slightly.
Ensuring Proper Magnetic Seal
The magnetic strips should meet evenly from top to bottom. If there's a gap, check that:
- The screen isn't twisted or bunched on one side
- Both panels hang at equal lengths
- The adhesive is firmly attached along the entire frame
Gently reposition the screen if needed while the adhesive is still fresh (within the first hour of installation).
Weight Distribution
If the bottom corners lift away from the frame, the screen may be too tight. Loosen the side attachments slightly or add small weights to the bottom corners using the weighted strips included in some kits.
Maintenance and Care Tips
Keep your magnetic fly screen functioning properly with regular maintenance:
Weekly cleaning: Wipe down the mesh with a damp cloth to remove dust and debris. This prevents buildup that can weaken the magnetic seal.
Monthly inspection: Check that all adhesive strips remain firmly attached. Reapply or reinforce any loose sections immediately.
Seasonal storage: Remove and store your screen during winter months if not needed. Roll it loosely and keep it in a dry place to extend its lifespan.
Avoid harsh chemicals: Clean with mild soap and water only. Harsh cleaners can damage the mesh or weaken adhesive bonds.
Most magnetic fly screens last 2-3 seasons with proper care. Replace them when the mesh tears, magnets weaken, or the frame no longer adheres securely.
Frequently Asked Questions
Can I install a magnetic fly screen on a sliding door?
Yes, magnetic fly screens work on sliding doors. Measure the door opening and choose a screen designed for wider frames. The installation process is identical, though you may need additional reinforcement along the top edge for larger openings.
Will the screen damage my door frame?
Quality adhesive strips remove cleanly without damaging paint or wood when you follow the manufacturer's instructions. Test a small area first if you're concerned, or use the thumbtack mounting option instead.
Can pets use magnetic fly screens?
Most dogs and cats learn to push through magnetic screens within a few days. The magnets are strong enough to keep insects out but light enough for pets to pass through. Some screens include reinforced bottom sections specifically designed for pet use.
How do I stop the screen blowing open in wind?
Ensure all edges are firmly attached and consider adding weighted strips to the bottom. Position the screen on the sheltered side of your door if possible, or choose a screen with stronger magnets rated for windy conditions.
Can I cut the screen to fit an unusual door size?
Yes, most magnetic fly screens can be trimmed with scissors. Cut carefully along the reinforced edges, avoiding the magnetic strips. Seal any cut edges with fabric glue to prevent fraying.
