how long does mortar take to go off

Hi there, Id give it 24 hour to completely go off, but normally the next day it will be fine. Also depends on the weather. Regards MDH BRICKWORKS

Depends on a lot of different things.Temperature whilst laying,type of brick or block,whether the bricks or blocks are wet at the time of laying etc.Also what do you mean by going off? Enough to iron it in? Enough to lean on the wall? Could do with a bit more info.

IT CAN TAKE UP TO FIVE DAYS WITH ENOUGH RETARDER IN IT WITHOUT ANY AGENT SHOULD START GOING OFF OVERNIGHT AS LONG AS ITS NOT BELOW TEMP
