hi all,
Had patio done 2 months ago by landscaping co. Slabs are Indian Sandstone ‘Raj Green’. They were varied Autumnal colours prior to grouting, browns/reds/yellows..
Problem is there is a picture frame effect in & around the grout lines. The slabs are bone dry but look wet around the edges. Some are quite big stains running into the centre of the slabs.
The raj colours also seem to have been lost, they look more grey now. Almost looks like a residue covers the slabs now? The grout used was mushroom grey so I’m wondering if it is grout residue or something else?
Sandstone was NOT sealed. Grout used was a dry brush in type.
Patio has been cleaned twice, first with washing up liquid, stiff brush. Second time with patio cleaner, stuff brush & jet wash. Still no better.
Company said it will fade. I doubt it. Would rather try to clean them up & sort it out myself so I can actually enjoy looking out on my patio!!
I really need to avoid anything harsh/acidic if possible as there is an aluminium track & glass around the perimeter of the patio. That’s another reason why I’m worried if they come back to clean it, they may ruin the ballustrade.
How do I sort this mess out? The patio is 50m2. Thanks
