Be careful if you decide to seal it. A neighbour of ours had his sealed soon after laying it and it trapped the white effelecence between the surface of the stone and the sealent.
Yes, there is a risk of that, maybe they did it too soon after laying the patio? I think it's best to wait 2-3 months so I'd probably be doing it next spring after a gentle clean.
Pointing done and all finished. Just a bit of turfing to lay but will be keeping off it for a couple of days. Pleased I went with Raj Green, I just need to decide whether to seal it at some point...

By comparison, this is how it looks when wet with rain. I like the contrast between how it looks when wet & dry, which I guess will be lost if I seal it?
I’ve never considered putting a sealant on my paving @LeadFarmer as I like the natural look. Are there any off cuts left of your sandstone? If so, you could try some sealant on a bit, leave it to weather for a while and then decide. A sealant will prevent water being absorbed by the stone so the wet and dry colour contrast will be weaker than without it.
