A water-based acrylic roof coating providing long-term waterproofing, anti-corrosion and UV/weather resistance on metal roofing systems.
Summary Benefits at a Glance
Seamless waterproofing – continuous acrylic film, no joints or leaks
Weather & UV resistance – durable under sunlight, rain and temperature cycling
Strong adhesion – bonds to galvanized steel, aluminum, concrete and tile
Easy & safe to apply – water-based, brush/roller/spray application, low odor
Product Introduction
This acrylic roof coating is formulated for metal roofing waterproofing and anti-corrosion applications. The water-based acrylic polymer forms a flexible, crack-bridging, seamless film with excellent adhesion and long-term durability. It resists UV radiation, thermal movement, salt spray and general atmospheric corrosion. Typical uses include industrial workshops, warehouses, commercial buildings, stadiums and metal roof renovation projects. The system can also be used on compatible concrete/tile roofs after proper priming and detailing.

Product Usage
Application Areas
Metal roof waterproofing and restoration for factories, warehouses, commercial/public buildings
Large-span roofs, stadiums and distribution centers
Compatible concrete/tile/composite roofs (after priming)
Construction Notes
Substrate prep: Remove rust, loose paint, dust/oil; repair leaks; dry and clean. Treat fasteners, laps and penetrations；use rust-inhibitive primer on corroded metals.
Application: Stir well; apply first coat uniformly (roller/brush/spray). After drying, apply second coat perpendicular to the first. Reinforce lap joints, seams and details with polyester fabric where needed.
Curing & weather: Avoid rain/ponding within ≥24 h; do not apply when substrate <5 °C or >35 °C, or during rain/strong wind. Protect finished film from puncture.
Maintenance: Periodic inspection; clean with neutral cleaners; repair damaged areas promptly.
