The Guardian Seal coating process

Step 1 - We Clean

A comprehensive chemical treatment is applied to effectively remove organic growth such as moss, mould, and lichen, followed by high-pressure water blasting to restore surfaces to a clean, pristine condition.

Step 2 - We Prep

Surface preparation involved mechanical fixes, rust conversion using rust converter, roof and fibreglass patching, silicone sealing, screw replacement, and repairing or replacing broken tiles to ensure long-lasting protection.

Step 3 - We Prime

As part of the restoration process, we apply a high-quality primer to prepare surfaces for sealing or coating, ensuring optimal adhesion and long-term durability.

Step 4 - We Seal

To complete the process, we apply two coats of Guardian Seal, creating a resilient, weatherproof barrier that locks in protection and extends the lifespan of the roof surface.
