Evaporative Cooler Coating 1-QT Asphaltic-Coated - DIAL 5347 (2-PACK) NOTE: THE CANS ARE DENTED. The DIAL 5347 asphaltic-coated evaporative cooler coating is a premium, heavy-bodied, one-application formula engineered to seal and protect the bottom pans of swamp coolers against rust, corrosion, and moisture penetration. Formulated with highly refined asphalt and proprietary adhesives, it bonds permanently to metal surfaces, creating a durable, waterproof barrier that extends the life of cooling units and reduces maintenance costs. Designed for direct application to corroding or aging cooler pans, it inhibits rust formation, dampens operational noise, and resists degradation from constant water exposure ? delivering long-term protection with a single coat. Non-asbestos and fast-drying, it is ideal for seasonal maintenance and restoration of evaporative cooler purge systems in residential and light commercial settings. Features - One-coat application eliminates need for multiple layers or touch-ups - Premium asphaltic formulation bonds permanently to metal surfaces - Creates a waterproof, moisture-resistant barrier against constant water exposure - Inhibits rust and corrosion ? extends pan life and prevents leaks - Reduces operational noise by dampening vibration and resonance - Non-asbestos formulation for safer handling and compliance with environmental standards - Fast-drying ? ready for use within hours of application - Applies easily with a hard-bristle brush or putty knife - Compatible with galvanized steel, aluminum, and other common cooler pan materials - Resists cracking, peeling, or flaking under thermal cycling and humidity - Designed specifically for evaporative cooler purge systems and drain pans - 1-quart size provides ample coverage for standard residential cooler pans - Packaged as a 2-pack for seasonal maintenance or multiple units Specifications - Brand Name: DIAL - Model Name: DIAL 5347 - Product Type: Evaporative Cooler Coating - Material: Asphaltic-Coated - Color: Black - Volume: 1 qt per can - Quantity: 2 pcs per pack - Finish: Asphaltic-Coated - Type: Premium - Weight: 2.1 lb per can (4.2 lb total) - Dimensions: 4.25x4.25x5.0 in - Packaging: Can - Country of Origin: United States - Nomenclature: 5347 COOLER COATING QUART - Application Method: Brush or Putty Knife - Drying Time: Fast-drying ? surface dry in 1?2 hours - Compatibility: Evaporative cooler drain pans, purge systems Product Application The DIAL 5347 evaporative cooler coating is used by HVAC technicians, maintenance professionals, and homeowners restoring or maintaining evaporative coolers in arid climates where units operate seasonally under constant moisture. Ideal for sealing rusted or deteriorating drain pans in window-mounted or whole-house swamp coolers, it prevents water leakage, structural decay, and costly replacements. Its one-coat design simplifies seasonal maintenance, allowing users to extend the life of aging equipment without full system replacement. The coating?s noise-dampening properties also reduce operational vibration, enhancing comfort in residential and light commercial environments. Professionals specify it for its reliability, ease of use, and long-term performance ? delivering the confidence that cooling systems remain watertight, quiet, and functional throughout the cooling season.
