    Is there temp you need for proper curing of rtv,I have put my smoker together and I am chomping at bit to close some gaps b4 I can season and start smoking on it. It is 36 deg. in garage.
  2. Usually 70ish on the low side....but after the RTV is in place, heat helps it cure faster. I just did a mod. on my smokehouse and upon completion I fired the smokehouse up and ran it to 275*; no smoke. This set the RTV.

    Just be sure you are using high temp silicone-not all red is high temp.

    Better check the manufacture's website for directions. Most cure is based on (temp)(time). Lower temp means longer cure time. I'm sure that as long as it is above freezing the rtv will cure, just may take longer.

    red, food grade, 650 deg.Thanks for quick reply
  5. Here's a thought...
    You could heat the metal where you want to seal using a blow drier. The metal will act as a heat sink. Apply the sealer, then use the blow drier to keep it warm for a little while. Seal all your cracks, then heat the smoker up with no smoke.
    If sealing the ceiling, I would not go above say 175~200* so the sealer will not sag.

    I will try out your advice bc I am tired of waitind for it to get warm enough to apply. I have a heat gun and will use low setting. Apply enough heat till the sealant skins over. Thnx
  7. just be sure to preheat the metal first and you should be good...

    Silicone will skin over in one hour and fully cure in 24 hours under normal conditions. Allow more time for cold or very dry conditions
