I don't actually know what that means,I thought someone might know-how much to put in with say 4 shovels of sand to one of cement! I don't know what a glug is either!
What if using say 1-2 shovels of cement, so,8 sand 2 cement! How much plasticiser? Also when doing brickwork and have to fill in gap with brick, how small can gap to be filled be?
