Do you add water before or after pouring your bag of postcrete into its new home? This is a question that comes up a lot so let me help you out.
Water First or Last?
So, should you add water first or last? Well, most postcrete manufacturers say to add the water first, and this is what I would do if it is possible.
That is the key point though, it may not always be possible to add the water first. You may find that you add the water to your freshly dug post hole and it all just simply drains away. What do you do now?
Well, you can add the water after the postcrete, it really isn’t going to affect things too much. just make sure you use a stick or a rod and try to mix the postcrete into the water in the hole.
This won’t affect how long the postcrete takes to set, or indeed the final strength of the cured postcrete. It just requires a little more work when it comes to making sure the water is properly mixed in with the postcrete.
What is postcrete?
Postcrete is a fast setting concrete used to set posts for fencing, decking or whatever you need a set post for. Postcrete is popular due to how quickly it sets and for the fact that it is a lot simpler to use than concrete
Postcrete is a lot simpler to use than concrete as you don’t need to mix it and you don’t need to add any aggregates, everything you need for the mix is already in the bag.
Postcrete vs Concrete, what’s the difference?
again I have a full article on this, find it here: Postcrete vs Concrete
So what exactly is the difference between these two? Well the most obvious, and the one you will notice straight away, is how you use the two. Postcrete is much easier to use than concrete, no mixing is required, just chuck it in your post hole add some water and away you go.
When using postcrete all you have to do is add water to your post hole and then chuck the postcrete in. That’s it, no mixing at all. The postcrete will then proceed to set over 15-20 minutes from my experience.
Contrast this with concrete which you have to pre-mix and mix well before putting it anywhere and you can see that postcrete is much easier to use, when setting posts at least.
