ASTM D4479/D4479M-07(2024) PDF

Overview

ASTM D4479/D4479M-07(2024) is an international standard specification developed by ASTM International for asbestos-free asphalt roof coatings. This specification outlines the composition, physical properties, and application requirements for two types of brushing or spraying consistency asphalt roof coatings, designed to provide effective protection and performance for roofing applications. The standard supports the use of asbestos-free materials to enhance environmental and worker safety, aligning with global best practices.

Key Topics

• Types of Asphalt Roof Coatings
  • Type I: Manufactured from self-healing, adhesive, and ductile asphalts.
  • Type II: Made from asphalts with a high softening point and relatively low ductility.
• Material Composition
  • Asphalt base
  • Volatile petroleum solvents
  • Mineral or other stabilizers (excluding asbestos)
• Performance Requirements
  • Water content, nonvolatile matter, and stabilizer/bitumen content limits
  • Physical properties such as uniformity, consistency, and pliability at different temperatures
  • No separation or settling after storage, and specific application rates for optimal coverage
• Application Methods
  • Suitable for application by squeegee, three-knot brush, paint brush, roller, or spraying
• Quality Control and Inspection
  • Testing methods for verifying composition and physical requirements
  • Clear guidelines for rejection, reinspections, packaging, and marking
• Safety and Compliance
  • User responsibility for safety, health, and environmental compliance during use

Applications

ASTM D4479/D4479M is widely used in the building and construction industry, particularly for:

• Roof protection and maintenance for commercial, industrial, and residential structures
• Application on prepared roofing, saturated felt, and metal surfaces for improved waterproofing and weather protection
• Situations requiring asbestos-free solutions to meet modern health and environmental regulations
• Projects needing reliable, uniform coatings that meet specified performance standards for durability, adhesion, and temperature performance

The standard supports the use of safe, high-performance roof coatings that avoid asbestos-related health risks while providing effective coverage and long-term protection.

Benefits

• Promotes use of safer, asbestos-free building materials
• Ensures consistent product quality and performance
• Enables manufacturers, architects, and contractors to specify compliant roof coatings with confidence
• Facilitates compliance with local and international regulations and procurement requirements
