Measuring & Mixing Catalyst         

Don’t take chances here!  Make sure you know the required percentage for the specific product (if in doubt, check the Technical Data Sheet in this web site), and measure carefully.  Over catalyzing can cause “burning” of the finish, causing it to amber and, over time, to become brittle and prone to cracking.  Under-catalyzing will result in a relatively soft coating that can lead to re-coating issues such as wrinkling.  It will also cause the lacquer to “gas-off” for months instead of days.

 When mixing catalyst and thinner into post-cat lacquer, add the catalyst first, then thinner as required.  Pour slowly while stirring to avoid “catalyst shock”.
