Clean Up:
Clean up uncured adhesive residue with
mineral spirits. Scrape away cured adhesive
using a sharp-edged tool.
19 = Year of Manufacture
038 = Day of Manufacture based on 365 days per year
For example: 9038 = February 7, 2019
* Time is dependent upon temperature, humidity, porosity of substrate and amount of adhesive used
** Cure time is significantly increased in cold temperatures and/or low humidity conditions
