The mixing ratio of WB Epoxy Color is 1 part A (resin) to 1 part B (hardener) except for black which is 4 parts A (resin) to 1 part B (hardener). Mix each component separately. Check the batch number on Part B (hardener) containers. If the batch numbers are not all the same, then mix all containers of Part B together prior to achieve a uniform color. Mix part A and B together (only the amount that can be used within 2 hours) using a low speed drill motor and mixing paddle for 3 – 5 minutes scraping the sides and bottom of the container.
IMPORTANT: Allow the mixed material to sit for 10 – 15 minutes induction time prior to application. DO NOT use mixed material beyond 3 hours from the mixing time even though the WB Epoxy Color appears unchanged.
