Do-it-Yourself: Painting Metal Gates

Metal garden gates need a fresh coat of paint every few years to keep them looking good and to protect them from the elements. Painting them with a brush is a slow and tedious process and is difficult to cover the whole surface without getting drips and runs. Using a paint sprayer speeds up the process making it quick and easy to transform your gates and protect them for years to come. We will show you all the required steps to get the job done.

Step-by-step Guide for Painting Metal Garden Gates

Step 1 of 8: Cleaning the surface

Cleaning the surface

Start by giving your metal garden gate a thorough clean. Using washing up liquid and plenty of warm water with a sponge or soft bristle brush, wash the rails then rinse with cold water and leave to dry.

Top Tip: A jet washer can really speed up this process.

Step 2 of 8: Always wear the appropriate PPE

Always wear the appropriate PPE

We would recommend a dust mask, glasses and gloves.

Step 3 of 8: Remove old paint

Remove old paint

If the paint is flaking or the surface is rusty remove as much as you can with a wire brush. Using sandpaper, sand down any areas which have raised paint to achieve a smooth surface.  Go over the entire surface again with wire wool to scratch the surface and give it a key for the new paint to adhere to. Remove any dust, grease or dirt by wiping the surface with a rag soaked in white spirit.

Step 4 of 8: Preparing the paint and primer

Preparing the paint and primer

Use the included stirring stick to mix the paint and the primer. Ensure they run smoothly off the end of the stirrer and immediately dissolve into the paint or primer without leaving a trail on the surface. If you do need to dilute them, follow the manufacturer’s instructions. Each notch on the stirrer corresponds to a 10% dilution. Fill the spray paint container with your desired material.

Top Tip: Check the tins to see what the material should be diluted with. If the recommendation is to clean your tools with water, you only need to add water to dilute the paint.

Align the suction tube depending on how you are going to work – forwards when spraying downwards and backwards when spraying objects overhead.

The spray jet can be adjusted in three directions – horizontally, vertically and diagonally for detailed precise spraying.

Step 5 of 8: Test spray onto cardboard

Test spray onto cardboard

To check your spray pattern, carry out a test spray on a scrap of cardboard to find the right settings for you. Start with the lowest paint flow setting and gradually increase it to your desired paint flow.

Step 6 of 8: Priming the garden gate

Priming the garden gate

Remove the gates to make them easier to paint. As we have two gates we have joined them together so they stand up which makes painting them easier. If you put the gates on wooden blocks to raise them off the floor it is easier to spray all the way to the bottom. Using the detailed spray setting, start at the top of the gate and spray the main rail, scroll work and then the bars. Using a piece of cardboard as a spray shield removes any risk of overspray. Also spray any handles, latches or gate hinges.

Top Tip: Always press the trigger about 10cm before the edge of the gate so you are already moving when you start to spray. Keep the gun moving at a steady pace, holding it about 15cm from the surface. When you have passed the edge of the gate release the trigger and change direction. This avoids a build-up of thicker layers of paint during direction changes at the end of each pass.

Step 7 of 8: Spray the garden gate

Spray the garden gate

Allow the primer sufficient time to dry according to the manufacturer’s instructions. Meanwhile return any of the unused primer to the original tin and clean out the spray paint container. Fill the spray paint container with the metal paint. Do a test spray onto cardboard this will remove any remaining primer in the sprayer and you can also check the metal paint spray pattern. Follow the spray procedure in Step 6 to apply the metal paint top coat. Allow the paint to dry following the paint manufacturer’s instructions.

Step 8 of 8: Apply a second coat

Apply a second coat

As it is so quick and easy to spray paint the gate, it is worthwhile considering applying a second coat for ultimate protection.

The result

The metal garden gate is transformed and looking like new again, protected from the elements for years to come.
