i use it all the time for decking and fencing etc. I use the hanson stuff which has a good mix in it. the only thing i do sometimes is add the rapidmix cement to it. It should all be premixed anyway. I find the best way is to pour it all in dry, ram it down with a metal rod and then pour about 1/2 a can of water in it. After that leave well alone.

that sounds like the blue circle stuff. Goes off quick, but as i remember theres sod all aggregate in it, so it lacks strength. Try getting the hanson stuff. Most builders merchants and fencers sell it

I was a bit confused as the yellow bags did not have a blue circle on them - even though they were the blue Circle yellow. Anyhow, had a look and they are marked "Lafarge". A quick Google shows Blue Circle as a subsidiary of Lafarge.

Try B&Q for Hanson products, our branch stocks that particular brand. I used 10 bags in the summer, lots of small aggregates in the mix.

I've never met a fencer that uses Postcrete or any other quick set product. After all - what's the rush?
Thermo
especially once youve put the panels in as well! Joe strikes again! Hey Wabbit you must be as unprofessional as me if you use pre-mixed stuff!
