Product Information

Full details

The Ultra V1 Waterproof Roofing Top Coat is designed for homeowners and trade professionals seeking a durable, long-lasting solution for flat roof sealing, gutter maintenance, and general surface repair. Its standout feature is its rapid, UV-curing resin technology that ensures a resilient, weather-resistant barrier, though users should note that optimal performance is strictly tied to exposure to UV light for the final hardening process.

FAQs

Does this product require a catalyst?

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

Can I use this on metal roofs?

Yes, it is designed for excellent adhesion to metal, as well as timber and masonry.

Will it cure if there is water on the surface?

Yes, it is capable of curing under up to 20mm of clean water.

How long does the protection last?

When applied correctly, it provides a sealed, weather-resistant finish for up to 25 years.

Is it safe to use indoors?

It is low-styrene and peroxide-free, but ensure adequate ventilation during application, and you will need a synthetic UV light source to trigger the cure.

Troubleshooting

The coating remains tacky after several hours.

The resin requires more UV exposure; move the object into direct sunlight or increase the intensity of synthetic UV light sources.

Poor adhesion to the surface.

Ensure the substrate was completely free of grease, oil, or loose particles before application. Scuff smooth surfaces slightly to improve mechanical key.

Pros and Cons

Simple one-step application process
Effective in damp conditions and underwater

Setup, Compatibility & Care

Before application, ensure the substrate is clean, dry, and free of loose debris. While the product can handle residual water, heavy grime or grease should be removed to ensure maximum bond strength. Apply directly from the container using a brush or roller. No mixing is required, which minimizes waste and application time. For ongoing care, periodically inspect the cured surface for physical damage. If a puncture occurs, the area can be easily cleaned and over-coated with a fresh layer of Ultra V1, as the new resin will bond seamlessly to the existing cured material.
