Postcrete vs concrete: which is better?

Postcrete and concrete might seem very similar. They’re both cement-based products and they can both be used for jobs such as fixing fence posts and rotary washing lines. But there are a number of key differences between them when it comes to things like strength, cost, setting time and convenience.
Should I use Postcrete or cement?
Postcrete, also known as post-fixing mix, is a ready-to-use blend of cement and other ingredients that doesn’t need to be mixed. It was made especially for setting fence posts in the ground.
On the other hand, cement itself has to be mixed with water and aggregate (rock, sand or gravel) in the correct ratio to create concrete.
When it comes to choosing between the two, there are a variety of factors you’ll need to bear in mind.
Convenience. Postcrete comes ready to use. On the other hand, to make concrete, you’ll need to mix to the correct ratios in order to make sure it’s strong, durable and workable.
Setting time. Postcrete sets much faster than concrete – it can support a fence post after as little as 5 minutes, whereas ordinary portland cement can take up to 2 hours to set.
Strength. Concrete is stronger than Postcrete. However, you may not need anything stronger than Postcrete for your project, depending on what you’re hoping to use it for.
Cost. Postcrete is generally more expensive than concrete.
As a general rule, Postcrete is ideal for fixing fence posts, rotary washing lines and smaller gate posts. However, it shouldn’t be used for general concreting, render, grout, mortar or screeds. Which brings us onto…
Should I use Postcrete or concrete for fixing fence posts?
Postcrete and concrete are both suitable for fixing fence posts. However, Postcrete was designed especially for the job, and makes fixing fence posts much quicker and easier. Its fast setting time means you could quite easily install all your fence posts in one day, before letting it cure overnight – something you’d struggle to achieve with concrete.
Most professional landscapers use Postcrete as it enables them to complete jobs more quickly. So, you can be confident that it’s up to the task!
Having said that, Postcrete is more expensive than concrete. Ultimately, it’s all about whether you value your time or your money the most.
