Resealing vents while installing new Maxim skylights. Stripped off all old sealant and resealed with Sikaflex 221. I have several tubes of Dacor self leveling and would like to top over the Sikaflex. Not sure if the two might not react well to each other.
Try a simple experiment. Put some Sikaflex on a piece of scrap metal, let it set up, and put the Dicor over it. Let that sit around for a week or two and see what happens. Having it be exposed to the sun might help the experiment.
