I've just laid a new slab path, it was laid on sharp sand and I'm pleased with the result. However, I had some sharp sand left so I used it for the dry pointing in a 1 to 4 mix. It's rained several times since I did the pointing and the dry mortar mix has not set hard, it’s still as loose as when I brushed it in. I have a horrible feeling that I should have used soft sand so that it bonded to the cement in the dry mortar mix, am I right?

almost
what you should have done was a wet point mix. Brushing the stuff in dry never works.
Generally i point with 3-1 soft sand cement, sometimes 4-1. but never dry mix swept in
you will need to remove it all and start again i'm afraid!

An update, I dug out the dry mix and replaced it with a 3:1 soft sand wet mix with some buff colouring added. I used a mortar gun this time which worked well and avoided staining on the slabs (the reason I tried a dry mix first time around). It's fine now!

Because I'm a DIYer and don't know any better, but then the mistake only cost me a small bag of soft sand and a little bit of cement, my times comes completely free!
