Wood filler not setting

[blackbirdxx]

Hi,
I have made some wood repairs using 2 pack resin wood repair paste in a quite cold unheated lean-to room. Now I've found that the repairs have not set, even after 24 hrs. I've had an idea to put a heater in the room hoping that this will trigger the necessary chemical reaction. Am I likely to be wasting my time doing this before I leave a heater on all night? Is the only option to remove all the filler and re-do this work in a ready heated room?

thanks for any advice...

Heat does no harm in this situation, but the resin is exothermic anyway......was the filler old, and did you get the mix right?

Stupidly, I wasn't too careful with the mix proportions but I did mix it well. Filler was new....

So my question is, is a night with a heater likely to cure this problem assuming the mix proportions are OK?

Unless its a faulty batch then it should cure fine.....maybe there’s a minimum temperature stated in the instructions?
Certainly I haven’t had any problems around the 10deg mark.

Hi,
Thanks,
Having used it and it failing I read that temperature is the main reason and shouldn't be used in low temps below about 15C. Mixture is the other reason as you say. I think I'll heat the room over night to see if that does the trick. If not, I guess it's a matter of scraping it all out.... great!!

If you were a bit light with the catalyst it will take longer to cure, but it will get there if its warm.
Be lucky!

Great to know that it will go off eventually with a bit of warmth...thanks.
