I waited for more than 20 mins. I am using Silmar 249A polyester surfboard resin. Does this resin ever get tacky? Thanks

However, in general terms of normal polyester resins, There should definitely be a tack stage. Did it go off at all?? Check your catalyst ratio very carefully and also consider the temperature of the environment you are working in. The colder it is the longer it takes to go off and in extreme cases temperature can stop it curing at all. Warren Penalver Easy Composites / Carbon Mods - Technical Support Assistant
