Hi all I recently used spraymax to clear a refinish. It was very cold in my garage when I sprayed it around 40 degrees and I got some runs but no big deal. However the clear is still soft 2 days later. I brought it inside last night and put it next to radiator and it felt a little harder this morning. Would baking it in the oven for a few hours help? Thanks
I would not put it in an oven. When those burners cycle they throw far more heat than what the thermocouple is set at, trying to reach the set point as fast as possible. You may end up with scorched finish. I think you should keep it inside and wait it out.
That’s a great point thank you! I read on an auto forum that the catalyst in clear coat will go dormant if temp is under 65 degrees. Then it won’t harden at all. My basement is about 62 so hopefully it will work.
This is absolutely from the low spraying temperature, DO NOT try to speed up the drying. The offgassing of this type of lacquer is really important and if you force heating, the top layer will harden and the lacquer underneath will remain soft for an indefinite amount of time. The lower drying temperature may work in your advantage, but I think 67-ish would be best. Maybe see if you can get the temperature there slightly up and have patience Same thing happened to me once and I already feared I'd have to redo it, but it did harden nicely in about 3 weeks at room temperature.
Thanks! It is definitely getting harder. I hope this is a 2k urethane or I may have a lot more problems!
Thanks all! Patience has won and I am knocking it down with 800 right now preparing for flow coat. Thanks everyone again as your feedback saved this bass from burning in an oven
