Catalyzed lacquer means that the lacquer dries through the process of evaporation. A pre-catalyzed lacquer has the catalyst added at the factory. A post-catalyzed lacquer means that you add the catalyst right when you are using it. Pre-catalyzed lacquers take a bit longer to dry, but they are definitely convenient to use. That’s why pre-catalyzed lacquers have basically become the standard in lacquers nowadays. Post-catalyzed lacquers dry faster, but they are more complicated to use due to the added steps involved. Chemically they are practically the same in the end. Your lacquer preference and needs may vary. Talk to your Bonds Décor Ottawa lacquer specialist about which lacquer is right for you.
