So do you think their Calcium choride/Magnesium chloride is going to be ok for cement that was put down this spring! Or am I better off with the much more expensive straight Calcium Chloride.szorno said:If you have a Sams' Club nearby, they have a Calcium chloride/ Magnesium chloride bagged mix for about $6 per 50lb bag. Cheap and works well. We used on 2 year old concrete with no issues even 3 years later with the same product every year.
If it was my concrete I'd be only using sand or nothing at all, but it is for walkways around a 2 story Dr office complex. I know they would never go for sand being it's the main walkways into the buildings, carpet would be trashed very fast. The client insists on something of the calcium nature. I'm asking what is going to work better and maybe safer for his site, calcium/mag. mix or straight calium applied very lightly to highest traffic areas when needed.Chuck Smith said:I wouldn't apply anything other than sand to concrete less than a year old.
