The title kinda explains itself, but I have a bta on a rock that I need to drain the water level below to mortar it to another rock. The mortar cures under water but it can’t be applied under water and it’s best to give it a few minutes to cure, at least in my opinion. So how long do I have to work if the bta has to go above the water level?
