Product Information

Full details

The Seal It One Coat Liquid Membrane is designed for professional contractors and DIY enthusiasts seeking a durable, solvent-free alternative to traditional bitumen or GRP roofing systems. It provides exceptional waterproof protection for a wide range of surfaces, including metal, wood, and concrete, by creating a highly reflective barrier that requires no heat or complex bonding. While it offers versatile, primerless adhesion, users must ensure that all cracks larger than 2mm are pre-filled and irregular masonry is leveled before application to achieve a successful, long-lasting seal.

FAQs

Can this be used on bitumen roofs?

Yes, the Seal It system is specifically designed to work as an alternative to bitumen-based membranes and can be applied over existing bitumen coatings.

Does it require a primer?

The system offers primerless adhesion to most standard building materials, though you may require additional system components like an accelerator or reinforcing mat for specific repair needs.

Is it flammable?

No, it features a non-flammable, solvent-free formulation.

What is the maximum pitch for this roof membrane?

It is intended for use on flat roofs and pitch roofs of up to 10 degrees.

How should I treat large cracks?

Any cracks wider than 2mm must be filled and leveled with a suitable filler before the liquid membrane is applied.

Is this product suitable for use on plastics?

Yes, it is compatible with a wide variety of plastics and polycarbonate surfaces.

Troubleshooting

Coating not adhering to the substrate

Ensure the surface is completely clean, dry, and free of grease or loose debris before re-application.

Visible cracks remaining after application

If cracks exceed 2mm, they must be filled with a compatible sealant or filler prior to applying the liquid membrane.

Uneven finish on masonry

Ensure all irregular masonry is leveled and smoothed before the application of the membrane.

Pros and Cons

Pros

  • Non-flammable and solvent-free formula
  • Highly versatile across multiple roofing substrates
  • No heating or specialized bonding equipment required
  • Excellent for both flat and pitch roofs under 10 degrees
  • Provides a high-reflectivity surface for temperature control

Cons

  • Requires pre-filling for cracks wider than 2mm
  • Irregular masonry surfaces must be leveled before use
  • Limited effectiveness on roofs with a pitch greater than 10 degrees
  • May require additional system components (accelerator/mat) for complex repairs

Setup, Compatibility & Care

Before starting, inspect the surface for debris, oil, or loose particles. For masonry, ensure all surfaces are level; fill any surface irregularities and address any structural cracks wider than 2mm with a suitable filler before applying the membrane. The product is compatible with a vast array of materials, including polycarbonate, lead, zinc, and fibre-cement. While the system offers primerless adhesion, always test a small, inconspicuous area if working with unique or aged substrates. Post-application, ensure the coating is protected from heavy rainfall until it has achieved its initial set.
