Patio pointing options

Hi fellow DIY-ers,

I’ve laid a new patio using concrete slabs, just wondering what my best option for pointing them would be?

They’ve got a slight chamfer on the edge, so the bottom of the slabs are touching, whilst the gap at the top is about 15mm.

I’ve seen the brush in resin options (sika etc), but these are quite pricey per tub and don’t think one tub would last very long with my big gaps.

Researched mortar options and it seems the consensus is to avoid a dry brush in mix as it will crack as soon as the cold weather comes. So how wet does it need to be?!

Final point - it needs to be a sand colour. I did a 6:1 trial mix of builders sand and cement and although it had a yellow hue, it was still quite grey.

TLDR: I need some sand coloured pointing for my patio - what are my options.

thanks in advance

I believe you can just use sand? Kiln dried silver sand?

Try white cement - the grey colour of normal cement is overpowering the sand. Also experiment with sand from different sources - the variation in colour may surprise you.

I would personally use a medium consistency - neither runny nor stiff - and gently trowel into the V shaped gap, tapping down well as you go. It's up to you at what point to stop - you can take it virtually to the brink or work to a set depth, determined by a piece of notched stick. Have a bucket of water and cloth ready, to mop away the inevitable odd splash which can easily spoil the result.
