Liam · Answer

3 parts sharp sand 1 of cement and wet mix ..mix should be firmish not over wet Wet joints leave for about a hour.Clear out gaps with rake tool,and when pointing remove excess from slabs,and have wet sponge and water to clear smears from slabs.
Best to use flat Pointing tool for smooth finish

I would recommend using a ready mixed product such as Rompox. This is very easy to use and can be applied in the rain, whats more it won't stain your slabs. (It is quite pricey though.)

Hi Daniel, typically it's a 3:1 ratio, however there are also other newer products available such as a resin grout mix that may be better suited.

Neil · Answer

A ratio of 2/1 .. 2 spades of building sand 1 spade of cement..mix more than you need to assure you have enough to do full area to make sure its all the  same colour when dry..

Amanda · Answer

We use slabbing grout rather than sand and cement. Sikens the brand is easy to work with and really good. A little dearer though.

Nicholas · Answer

4/1 ratio mix semi dry and it doesn't stain the flags then use pointing bars to push it in. Hose 24 hours after

Salman · Answer

3.1 ratio of sand and cement are mixed without the addition of ANY water.

Jason · Answer

We use easy-joint it’s a lot quicker and no staining on the paving plus it’s porous so ideal for sandstone.

Hi Matt from A7 Premium Fences and gates👍
In my professional opinion, if you have put down Indian sandstone down I wouldn’t suggest a mix of sand and cement for grouting as after a few months things tend too grow back through due too the cement cracking, ratio 3:1 if you do want too do it, best thing I use is silka comes in a wide range of colours and is the easiest thing too put in doesn’t stain slabs like sand and cement will and all round just a better finish, hope this helps
Kind regards 
Matt
