The Cromar PRO 25 Topcoat Resin is designed for professional roofers and DIY installers who require a durable, weather-resistant final seal for flat roof systems. By providing a chemically integrated finish over the primary laminate, this topcoat ensures long-term roof integrity and superior aesthetic results. Users should note that surface preparation, specifically light sanding of the base layer, is mandatory to ensure proper adhesion and consistent curing across the entire roofing membrane.

A single 10kg bucket of Cromar PRO 25 is formulated to cover up to 20sqm of roofing surface.
No, light sanding is a mandatory step to create a mechanical key for the topcoat to ensure a strong, long-lasting bond.
The resin is formulated for either one or two coats depending on the specific finish requirements of your roofing project.
You will need a brush for detailed edges and a roller for larger surface areas.
No, it is a cold-application resin designed for simple manual installation.
This product is specifically designed for flat roof systems and may not perform as expected on steep slopes.
Ensure the base layer was sanded sufficiently and all dust/grease was removed before application.
Avoid over-rolling the product; use a consistent application speed and ensure the roller is free of trapped air or debris.
Before starting, ensure the roofing surface is fully cured and free of debris. Use fine-grit sandpaper to perform a 'light sand' on the entire area, which creates the necessary mechanical key for the topcoat. After sanding, vacuum or sweep away all dust particles.
To apply, use a standard brush for edge detailing and a roller for large, flat surfaces. Work in sections to ensure the wet edge remains consistent. Avoid applying during periods of high humidity or impending rain, as moisture can affect the chemical bond and the final sheen. Store the bucket in a cool, dry place away from direct sunlight when not in use, and keep the lid tightly sealed to prevent the resin from hardening in the container.
