I'm experiencing the same issue. I have the most recent version of Java (6, Update 32) and I've republished my course in Presenter and I still receive an LMS API error message. We have a license on a couple of computers and I'm receiving the error on the other computer as well. Any thoughts?
Grout needs between 48 and 72 hours to dry before it can be properly sealed. Despite the fact that grout often looks dry within a few hours, sealing it too early can damage the grout and keep it from effectively doing its job. Keep Learning.
Check the recommended cure time on the mortar packaging and follow that. It varies depending on the type. I generally wait 36-48 hours to apply the grout afterward (I am cautious, that is far more time than is generally needed). â James Jul 14 '14 at 17:54. Better to give it time and make a trip to the laundromat than to ruin what looks like a nice tile job by being in a hurry. Nothing like a trip to the laundromat to make you more fully appreciate not having to go there all the time. I'd want to aim for a week's cure before putting in anything that heavy.
