Indian Sandstone Picture Framing/Grout marks

[Boggs]

Surely they would need to be sealed before laying that on them?
That’s like grouting with slc!

That's how all floor tiling used to be grouted @Boggs ..... sloppy and wet.

This is different though as it is rapid setting.

The Op's installers have done it wrong. (unless the grout stated was different)

They definitely weren’t sealed. How on earth am I going to rectify this now? I’ve contacted the boss of the company today, sent photos & he said he’s coming round tomorrow.

What worries me, is if they didn’t use this product right then what are they going to use to remove it? He said he usually uses the ready mixed grout eg easy joint so ‘maybe there was an issue with the dry grout’. No the issue was how you used it!

Anyone have any clue how to sort this? Please don’t say replace the patio, way past that option.
Are there any products at all that will remove this?

drop @Lithofin BOB a message and he may come up with a solution (pun intended)

Would a mortar remover work in this situation?

I wouldn't like to use an acid product on this stone.

Someone has used Sarsons pickling vinegar on sandstone before with good results, the thread is on here.

I'd try this new ltp product.

They were only meant to slightly wet the joints not the slabs, then brush in dry mix and leave for a while, then the dry mix sucks the water from the bottom of the joint then just smooth using a brick jointer and brush excess dry mix away. Now I would clean slabs with a cement film cleaner

Callatiler - is that Lithofin product ok on Indian sandstone? I’ve read some horror stories tonight about using acid based products. I see it says suitable for stone but ?

So essentially he grouted the entire patio, not just the joins but the surface of the slabs themself. Honestly this patio has caused me more stress than it was worth.

My other concern is the aluminium track & glass around the perimeter of the patio. How best to protect this from being damaged from these products
