- Masking tape and paper for any sunroofs, solar panels, water heaters or just anything on your roof you don’t want painted! Shieldcoat recommends Easymask (it is not just a clever name).

There are a few variations between tin and tile roofs although the methods of application are almost identical. So:
For tin roofs in addition you will need:
- Wire brush
- Spare roof screws if any needing replacing
- Electric screw driver
- Rustshield W (coverage rate is 5-6 m2 per Litre)
- Roofbond or Thermobond in the colour of your choice 5-6m2 Per Litre
For tiled roofs:
- If your roof has any mould you will need Mouldshield C
- CT 401 (coverage rate is 4-5m2 per Litre)
- Roofbond colour of your choice (coverage rate is 4-5m2 per Litre)
The process for metal roofs:
- SAFTEY! Once you know what safety your local council requires, set up your harness, safety rail and put on your non slip shoes and whatever other local regulations and laws you need to observe.
- Roof Inspection. Disconnect down pipes if you collect drinking water. Check your roof panels for any surface rust, loose roof screws and loose panels. If you find any surface rust you will need to wire brush these areas and remove all loose material from the surface. Also tighten any loose screws and secure panels. Replace any rusted screws.
- Roof Preparation: Using at least 3000psi clean the entire surface of the roof. Then rinse any residue away with a low pressure setting. There should be no chalky residue or any other dirt left on the surface of the roof. Let dry, this won’t take long on a sunny warm day.
- Primer. If your roof is older or has any surface rust you will need to use Rustshield W. If your roof is GREAT condition with no signs of imperfections then you can use Shieldseal W. Shake or stir your primer. Following the instructions for your Airless spray gun apply with your primer using the 517 spray tip. – Technique is very important we recommend you watch THIS VIDEO.
- Top Coats: After allowing 2 hours for your primer to dry you are ready to paint your roof. You will need to change your spray tip to the 521. Once again please shake or stir your Roofbond well. Apply your first top coat with the same technique you used to apply your primer, with even strokes and even coat (see spray technique illustration box) across the whole roof surface. Allow 2 hours between coats, By the time you have sprayed from one side to the other the wait should not be long.
- 2nd coat: repeat step 5.
- Step back and admire your newly restored roof, you have protected your roof and very likely added value to your home. Wait one week to reconnect down pipes if your roof is used to collect drinking water
The process for tiled roofs:
- SAFTEY! Set up your harness, safety rail and put on your non slip shoes. And whatever other local regulations and laws you need to observe.
- Inspect your roof. Check your ridge caps, pointing and tiles. Are there any broken tiles or damaged pointing and ridge caps? If so we advise you please to consult a professional. We would be happy to recommend a trades person in your area. We also recommend THIS SHORT VIDEO on what to look for.
- Roof Preparation: Check your roof for any signs of mould build up. If there’s mould you will need to apply Mouldshield C a heavy duty cleaner designed to kill off and remove mould and fungal growth. Apply liberally to affected areas leave for 30 mins. Clean off with high pressure cleaner.
- Cleaning: Using at least a 3000psi High pressure cleaner blast the entire surface of the roof. Then rinse any residue away with a low pressure setting. Rinsing will remove the chalky residue or any other dirt left on the surface of the roof. Allow time for roof to dry, this will not take long on a sunny day.
- Primer coat Application: Shake or stir your CT 401 primer well. Following the instructions from your Airless spray gun apply with your primer using the 517 spray tip. – Technique is very important we recommend you watch THIS VIDEO.
- Top Coats:After allowing 2 hours for your primer to dry you are ready to paint your roof. You will need to change your spray tip to the 521. Once again please shake or stir your product well. Apply your first top coat with the same technique you used to apply your primer, with even strokes and even coat across the whole roof surface. Allow 2 hours between Roof Coatings and apply 2 coats.
- Clear Coat:For an ultra-premium finish to protect you asset we recommend a coat of Nanoprotect 96. Apply 1 thin coat of NanoProtect SC-96 after Roofbond Roof Membrane is completely dry. Use a 517 airless spray tip, SC-96 covers at a rate of 10 square meters per litre.
- The value of your home has very likely just increased. Feel free to admire your hard work. Wait one week to reconnect down pipes if your roof is used to collect drinking water.
The technique for Roof Coatings:
- As you Spray keep your gun 15- 25 cm away from the roof.
- Keep the gun moving as you spray. Spraying one area for too long causes the the Roof Coatings paint to run.
- Keep the gun perpendicular to the surface you are spraying.
- Keep the bucket of paint your airless’ suction hose is in topped up, running it dry fills your hose with air rather than paint which takes some time to remove.
- Make sure your strokes are even and at the same height. We recommend 15cm from the surface of the roof. Make sure your spray technique does not resemble a golf swing but more of a ‘putt’
