Hi all, new to the forum although been a member of tilers forums for a while now. Been doing a bit of plastering in my own home where i am doing some renovations and a bathroom refit. Had to build an area up slightly by about 10mm with bonding coat. I didn't have time to skim over with multi finish the same day and was wondering if i now need to wait until the bonding is completely dry or can i go over it when it is still setting? been about 17 hours since i did the bonding coat. Any help would be much appreciated.
