Success requires following the complete system: cleaning with Mouldshield C, priming with appropriate sealer (CT401 or Fillabond), and finishing with membrane topcoat.
Tiles 10-25 years old typically need Shieldseal CT401, while very old or porous tiles require Fillabond's high-build properties for proper surface preparation.
Avoid application below 7°C or above 35°C. Allow extra curing time in winter months and avoid late afternoon application to prevent moisture issues.
Airless spray application delivers optimal results with specific tip sizes for each product (517 for primers, 521 for membranes).
When applied as a complete system, Shieldcoat provides fade-resistance guarantees unavailable with standard roof painting approaches.
All products in the system are certified safe for rainwater collection, maintaining your tank water quality while protecting your roof.
Look for chalky white staining (calcium salt leaching), patchy colour fading, or a powdery surface texture. Tiles over 10 years old typically show these signs and benefit from professional restoration.
CT401 is designed for tiles 10-25 years old with moderate weathering, while Fillabond is a high-build primer for very old, porous tiles that need surface resurfacing. Our technical team can assess which primer suits your specific tiles.
Yes, but proper preparation is critical. Loose or flaking material must be removed, and the surface thoroughly cleaned with Mouldshield C before applying our restoration system.
When applied as a complete system, our restoration provides decades of protection with fade-resistance guarantees. The exact warranty period depends on the specific products used and application conditions.
Absolutely. All Shieldcoat roof products are certified drinking water safe, so you can continue collecting rainwater from your restored roof without quality concerns.
Apply between 7°C and 35°C with no rain expected for at least 4 hours. Avoid late afternoon applications and allow extra curing time during winter months.
While our products are designed for professional application using airless spray equipment, experienced DIY enthusiasts can achieve good results with proper preparation and technique. We recommend consulting our approved applicator network for best results.
