How does this product work? Do you have to kiln afterward or put into an oven to cure the powder coat? Also, will it stick to ceramic or concrete?
This product is more designed for painting metal surfaces like your vent pipe and fireplace facing. It will work concrete and ceramic, but I cannot guarantee longevity. There is no kiln process. The heat from your fireplace will cure the paint. Make sure to turn off the gas supply to your fireplace before using it.
Would this be a safe paint to use to touch up the white birch vented gas log set that is used in the indoor fireplace? Our set got too much soot on them and when we tried to clean them it began taking off the powder coat!
It is not a hazard, as long as you turn the gas off before starting to paint and allow the paint to dry completely before relighting the fireplace. I cannot speak to how well the touchup paint will work. It is not designed for log touchup. Over time the paint on the logs will fade from the constant heat.
