Hi newbie here, I've taken a wall back to brick and hardwalled it however life got in the way and wasn't able to put another coat of hardwall on. It needs another few mm to flatten it as there's some low spots and not flat its dry as it been over a week. My problem is what do I use now? Do I soak the wall and put another coat of hardwall on or do I go over it all with bonding? Just worried about suction any help would be appreciated thanks
