Product Information

Full details

The Ultra V1 Waterproof Roofing Top Coat is designed for homeowners and professional contractors seeking a durable, long-lasting solution for roof repairs and flat surface sealing. Its primary benefit is a unique, rapid-curing formula that hardens under both natural and synthetic UV light, even while submerged in water, providing up to 25 years of protection. While it is highly versatile and easy to apply, users should note that as a UV-curing product, application timing must be managed carefully to ensure it doesn't cure before the surface is fully prepared and leveled.

FAQs

Do I need to add a hardener or catalyst?

No, Ultra V1 is a single-pack formulation and does not require any additional catalysts.

Can I apply this over existing GRP roofs?

Yes, it is specifically designed to overlay existing GRP roofs for repairs or surface rejuvenation.

Is it safe to use on metal surfaces?

Yes, the resin has excellent adhesion properties for metal, as well as timber and masonry.

How long will the seal last?

When applied correctly, the seal is designed to last for up to 25 years.

Does it require a primer?

No, the product is formulated to adhere directly to surfaces without the need for a primer.

Can it be used during rain?

It can cure under up to 20mm of standing water, making it suitable for emergency repairs during wet weather.

Troubleshooting

The resin is not curing as expected.

Ensure the application area has sufficient exposure to natural or artificial UV light. The product will not cure in complete darkness.

Surface appears tacky after expected curing time.

This is often due to insufficient UV exposure. Increase exposure to sunlight or use a high-intensity UV lamp to complete the curing process.

Difficulty spreading the resin.

Store the container in a warmer environment prior to use, as the resin viscosity can increase in cold temperatures.

Pros and Cons

Pros

  • No mixing or catalyst required
  • Can cure in standing water up to 20mm
  • Excellent adhesion across diverse materials
  • Low odor due to low styrene content
  • Ideal for both new roofs and patch repairs

Cons

  • Curing process is light-dependent
  • Requires careful planning for application area
  • Not suitable for use in complete darkness

Setup, Compatibility & Care

Before application, ensure the substrate is clean, dry, and free of loose debris or oil, even though the resin can handle some moisture. No primer is required for most surfaces, simplifying the workflow. Apply the product evenly using a standard brush or roller. Since the material reacts to UV light, keep the container closed and shaded while working to prevent the product inside the tub from premature curing. Store in a cool, dark, and well-ventilated area away from direct sunlight when not in use to maintain the integrity of the resin.
