Jointing compound for sandstone patio

[MugabesDeadCat]

A few years ago we got an Indian sandstone patio laid and they used Easyjoint for grouting.

The warranty we were given has expired now and the Easyjoint is just turning to dust and coming out of the joints so I want to regrout the patio.

Anyone got any recommendations?

I'm now expert and worried if I use mortar I'll get it all over the patio. I was looking at Ultrascape Flowpoint but have no experience of it.

It's not cheap but you need a resin based compound which does not crack and sets rock hard. I used this last year:-https://www.screwfix.com/p/sika-fastfix-jointing-compound-flint-15kg/912JJ?kpid=912JJ&ds_kid=92700037959161406&ds_rl=1241687&ds_rl=1245250&msclkid=393b48ffb2451b26b44b284a83c87903&utm_source=bing&utm_medium=cpc&utm_campaign=PX_Shopping_Everything%20Else&utm_term=4583657821125087&utm_content=A%20-%20Everything%20Else&ds_rl=1245250&gclid=393b48ffb2451b26b44b284a83c87903&gclsrc=3p.ds It does not set by drying but the resin in it cures by exposure to the atmosphere which takes about a day in summer temperatures. Have a look at people doing it on Youtube before you start and don't rush.
