how to read DAP caulk batch number (manufacture date, not expiration date)
I'm posting this here because I spent close to an hour online searching only to find lots of bad information. The below is what I ended up receiving directly from the help desk at DAP: There is a six digit batch number on the tube /container that begins with either a 1, 4, or 8. The number xxxxxxx can be read as follows: 1st number is the manufacturing warehouse 2nd and 3rd digit- year of manufacture 4th 5th 6th- actual day of the year. (It's from the Julian Calendar. We recommend that you go online and find one that you like and print it for use in the future.) 7th- internal number Most of our products have a shelf life of one year from the date of manufacture unopened. Our 100% silicones have a two year shelf life. So either product would expire xxx. For example, 124001 or 824001 would mean it was made in 2024 on the 1st day of the year. Expires a year later in an unopened container, or two years for 100% silicones. submitted by /u/mshep627 [link] [comments]
