APPLICATION INSTRUCTIONS
Prior to mixing stir part A mechanically. When all of part B has been added to part A mix continuously for 3 minutes until an uniform mixed has been achieved. Use a low speed electrical stirrer (300-400 rpm) to avoid air entrapment. To ensure proper mixing pour material into a clean container and stir again. Apply by brush, roller or airless spray.
CLEANING OF TOOLS
Clean all tools with Water immediately after use. Hardened and/or cured material can only be removed mechanically.
