ALDOCOAT 400 is a high solids, technologically advanced, fire retardant, thixotropic, 100% acrylic elastomer uniquely formulated for the protection of metal, SPF and a wide variety of other sloped substrates. The proprietary formulation incorporates premium elastomeric acrylic resins, reinforcing laminar pigments and nonmigrating fire retardants to produce a seamless, flexible, durable membrane having exceptional weatherability, ultraviolet and fire resistance. It acts as a breathing membrane allowing trapped moisture vapor to pass through the film while remaining impervious to exterior mass water penetration. The resultant tough, cured film provides good resistance to mechanical damage and chemical attack.

Uses
  • ALDOCOAT 400 is the ideal choice for metal roofs, BUR and single ply restoration.
  • This product is ideal for use over spray polyurethane foam and metal decks.
  • The thixotropic nature of ALDOCOAT 400 permits high build coverage, even on rough, textured or vertical surfaces without pinholing or sagging.
  • It also has excellent adhesion to a variety of other substrates, such as asphalt, primed wood, primed metal, concrete and masonry.
  • Ponding water conditions are to be avoided. Please contact our Technical Service Department for primer recommendations for application over rusted surfaces.
Application Instructions
  • ALDOCOAT 400 may be applied by airless spray equipment at a minimum rate of 1 - 2 gallons per square per coat.
  • Airless spray is the most efficient application method for larger projects. Brushes and rollers may be used for detail work such as edge termination, filling of voids, pinholes and small cracks.
  • Apply ALDOCOAT 400 only to clean and dry sound substrates free of loose particles or other foreign matter.
  • ALDOPRIME 708 Acrylic may be used to enhance adhesion over aged spray polyurethane foam roofs.
  • Do not apply product when ambient temperature falls below 50°F.
