Our Elastomeric Acrylic Waterproof Coating is a single-component, water-borne liquid-applied membrane engineered for long-term commercial roof restoration and waterproofing. Formulated with 100% acrylic polymers, the coating cures into a seamless, monolithic shield that accommodates extreme structural thermal movement.
Unlike heavy asphaltic systems or rigid coatings, this water-based formulation reflects solar radiation, reduces surface temperatures, and extends the service life of aging single-ply, metal, and concrete roofs without structural tear-off. Supplied in bulk liquid form for industrial spray, roller, or brush application.

Key Features
High Elasticity (350%+ Elongation): Accommodates cyclic thermal expansion and contraction of metal panels and concrete decks without tearing or delaminating at structural joints.
UV Resistance & Solar Reflectance: Pigmented with high-purity rutile titanium dioxide (TiO2), preventing UV degradation, chalking, and urban heat island effects.
Water Vapor Permeability: Breathable molecular structure allows trapped substrate moisture to escape outward, preventing blistering and interlayer delamination.
Low VOC Formulation: Water-based chemistry contains < 50 g/L VOC, complying with South Coast Air Quality Management District (SCAQMD) environmental regulations.
Single-Component Convenience: Requires no multi-part mixing on site, reducing applicator error and pot-life waste.
Application Areas
Metal Roof Restoration: Seals standing seam fastener heads, panel overlaps, and flashings to eliminate active leaks and prevent flash rust.
Modified Bitumen & BUR: Re-saturates and protects aged, dry, or granule-surfaced asphalt built-up roofs against moisture ingress and UV embrittlement.
Spray Polyurethane Foam (SPF): Serves as a mandatory UV-protective base/topcoat system over SPF roofing installations.
Concrete Roof Decks: Bridges hairline cracks up to 1.5 mm wide on poured or pre-cast concrete decks.

OEM & ODM / Customization
We operate as a direct contract manufacturer supporting global brand owners and regional distributors with complete private label services:
Rheology Adjustment: Custom viscosity profiles tailored for heavy airless roller application, high-output spray rigs, or brush-grade detail work.
Color Matching: Custom tinting available against standard RAL or NCS color cards (Minimum Order Quantity: 5,000 kg per batch).
Solids & Performance Tuning: Formulation adjustments available to meet specific regional wind-uplift, rain-fast, or elongation thresholds.
Packaging Customization: Steel pails (5 gal / 20 kg), plastic drums (55 gal / 250 kg), and intermediate bulk containers (IBC Totes / 1,200 kg) printed with custom artwork, barcodes, and multilingual compliance labels.
Manufacturing & Quality Control
Automated Dispersion Process: Production utilizes high-speed Cowles dissolvers and horizontal bead mills, ensuring median particle size dispersion under 25 microns for smooth film formation.
Batch Consistency Control: Every production lot undergoes rigorous laboratory testing for viscosity (Brookfield viscometer), non-volatile matter percentage, pH level, and density before release.
Accelerated Weathering Validation: Routine QUV accelerated weathering tests (ASTM G154) verify color retention, chalk resistance, and elongation stability past 2,000 exposure hours.
Quality Certification: Manufactured under an ISO 9001 certified quality management system. Full Certificate of Analysis (COA) provided with every container shipment.
Packaging & Storage
Packaging Options:
18.9 L (5 US Gallon) plastic/steel pails
200 L (55 US Gallon) steel drums
1,000 L (264 US Gallon) composite IBC totes
Storage Guidelines: Store in covered, dry conditions between 5°C and 35°C (41°F to 95°F). Do not allow to freeze.
Shelf Life: 12 months in unopened, factory-sealed containers. Stir thoroughly prior to application.
Reference Projects & Case Studies
Industrial Logistics Warehouse (50,000 m2 Metal Roof Restoration - Texas, USA): Restored an aging standing-seam galvalume roof using a 20-mil acrylic coating system, reducing interior peak building temperatures by 6°C (11°F) and eliminating active fastener leaks.
Commercial Office Complex (Concrete Deck Refurbishment - Melbourne, Australia): Applied a reinforced multi-coat system over a weather-beated concrete deck, passing a 48-hour ponding water test prior to handover.
FAQ
Q: Can this coating be applied directly over rusted metal roof panels?
A: No. Loose rust, scale, and flaking paint must be mechanically removed down to sound substrate (SSPC-SP2/SP3), followed by the application of our water-based rust-inhibitive primer prior to coating.
Q: What is the minimum ambient temperature required during application?
A: Application ambient and substrate temperature must be between 10°C (50°F) and 35°C (95°F). Relative humidity must be below 85%. Do not apply if rain is forecasted within 6 hours of application.
Q: Is a reinforcing polyester fabric required across the entire roof surface?
A: Full polyester reinforcement is typically required only over dynamic metal seams, splits, and flashing details. Field application of the coating can be executed directly as a reinforced or unreinforced multi-coat system depending on specification requirements.
Q: What is your standard Minimum Order Quantity (MOQ) for custom private label orders?
A: Standard MOQ for OEM bucket printing and formulation adjustment is 3,000 kg per product grade. Stock white formulations in generic packaging are available in smaller trial batch volumes.
