How much water should I add to a 20kg bag of PostFix?
As a guide, use around 2 litres of water per 20kg bag. Do not over water unless you need to achieve a sloppy mix. The less water the stronger the concrete.
Is Postfix a concrete?
Hanson Postfix is formulated to produce good quality concrete for setting all types of posts.
What's the difference between PostFix and concrete?
Concrete takes several hours or a day or two to set. PostFix sets in a few minutes, several tens of seconds, even, so you don't have to support the post for nearly as long as you do with concrete.
