REPAIR Ensure all screw and nail fixings are fixed correctly. Replace all rusted screws and any faulty sheet or valley irons as required.
CLEANING High-pressure wash with a minimum of 4000+ PSI and a minimum flow of 15-23 litres per minute with a turbo head/nozzle to remove dirt, excess grime, lichen, moss and other contaminants.
*PREVIOUSLY PAINTED SURFACES: High-pressure wash with a minimum of 4000+ PSI at 15-23 litres per minute with a turbo head/nozzle to achieve a satisfactory clean surface before application commences. Multiple passes may be required to effectively remove previous coatings.
Note: Allow the roof surface to completely dry between 1st and 2nd pressure wash, prior to the application of new coatings. Any remaining paint film should be checked using the cross hatch adhesion test to determine if existing paint is sound prior to coating – Refer to data sheet for full details.
*A previously painted roof can be re‑coated, however due to the variable nature of the original coating and its adhesion, we will not provide a warranty.
RUST REMOVAL Use a power tool or wire brush to clear all loose or flaking rust, where applicable. Then clean down with a broom or blower to remove all rust contamination or loosely bound material.

Application Method - Airless Spray
Recommended Spray Tip:
• Low pressure tip (Neon)

Do not pour leftover paint down the drain. If you have unwanted paint, brush it out onto newspaper, allow it to dry completely and then dispose it via your domestic waste collection.

Leave empty paint containers open in a well-ventilated area to dry out. Once dry, they can be recycled through the Dulux Envirosolutions® Program or disposed of via your local council’s recycling service. Recycling requirements may vary by location, so check with your local authority first. Do not reuse paint containers.
