Description
Eagle Aquapol – Instant Waterproof Roof Coating
Fibre-Reinforced Waterproofing for Emergency Roof Repairs and Maintenance
Eagle Aquapol is a high-performance, fibre-reinforced instant waterproof coating designed for the repair, refurbishment and protection of industrial and domestic roofs. Its flexible, wax-based formulation creates a continuous waterproof membrane in a single application, helping seal minor cracks, gaps and imperfections.
Aquapol is designed for rapid roof repairs and can be applied to suitable damp or wet surfaces, including during rainfall. Once applied, the coating provides immediate resistance to rainwater and will not readily wash off while curing, making it particularly useful for emergency leak repairs and ongoing roof maintenance.

Key Benefits
- Immediate waterproofing: Provides immediate resistance to rainwater following application.
- Fibre-reinforced formulation: Helps bridge and seal minor cracks and gaps.
- Single-coat application: Designed to provide waterproofing in one uniform application.
- Wet-weather application: Can be applied to suitable damp or wet surfaces, including during rainfall.
- Flexible waterproof membrane: Forms a continuous coating that accommodates uneven roof surfaces.
- No primer normally required: Applied directly to suitable, properly prepared substrates.
- Ready to use: Single-component product supplied ready for application after thorough stirring.
- Versatile roof repairs: Suitable for a wide range of common roofing materials and associated details.
Suitable Substrates and Applications
Aquapol is suitable for a range of roofing surfaces and repair applications, including:
- Galvanised steel, iron, zinc and other metal roofing
- Concrete and cementitious roofing
- Fibre-cement roofing sheets
- Roofing felt and asphalt
- Existing bituminous roof coatings
- Leadwork, slate and roof tiles
- Brickwork and suitable masonry surfaces
- Roof flashings, corrugated sheets and ventilation details
- Suitable metal and rigid PVC gutters, downpipes and drainage details
Important substrate restrictions: Do not apply Aquapol to extruded polystyrene (XPS) boards or PVC roofing membranes/foil. It must also not be used in areas likely to come into contact with solvents or oils. Always check substrate compatibility before application.
Application Instructions
1. Surface Preparation
- Ensure the substrate is structurally sound and free from loose material, dust, algae, dirt and other contaminants.
- Remove standing water before application. The surface may be damp or wet, but must not have pooled water.
- Repair significant cracks, splits, holes and surface damage before coating.
- Fill holes and imperfections with a suitable Eagle bitumen mastic where appropriate.
- Secure loose roofing felt using a suitable felt adhesive. Existing blisters should be cut, dried, re-bonded and sealed before coating.
- For larger cracks, use suitable reinforcement such as Eagle UltraFlex Matting in accordance with the manufacturer's repair guidance.
2. Mixing and Application
- Stir the product thoroughly before use to ensure an even consistency.
- Apply directly from the container using a brush.
- Distribute the coating in one continuous, uniform application.
- Apply at approximately 1–2kg/m², depending on the substrate and surface condition.
- Ensure cracks, joints, gaps and vulnerable details are adequately covered.
- In exceptional cases, a second coat may be applied 2–3 days after the initial application.
3. Drying and Curing
Aquapol is resistant to rainwater immediately after application. Typical drying time is approximately 2–3 days, depending on coating thickness, temperature and ambient conditions.
