I had some brickwork done next to my new Indian stone paving. The bricks were set in a pre-made mortar that dries to a light brown ie not regular sand and cement. The bricklayer managed to get some on the paving which wasn't noticeable as it was a bit wet when he finished. I see that acid is not recommended for Indian stone .

Neolith 325 is claiming its good for indian stone, any views on this ?

PS I wish I could add pictures to these posts (;-(

pictures are an absolute doddle. Have a play on photobucket for half an hour and if you cant post a photo at the end of it, you are a complete numpty :;): :D

Acid is ok on Indian sandstone (but never on any type of limestone).

Can you let me know what sort of stone you have and I will tell you how to remove the cement

All the best

Hi
Not used or tried the Neolith products but on reading up on it, it does sound ok, you could also give this company a call Tensid, speak to Richard Turk, and ask him to send you a sample of their Limestone restorer, I have used this loads of times on Sandstone, just dilute to 3:1.

Steve,
No disrespect mate but to say "acid" is safe on Sandstone on a forum is not the best advice, IE what acid is going to be used and what is the person wanting to do, to many chances of something going wrong IMV.

I hear what you are saying. Maybe I should have qualified the comment, but I wasnt really expecting Segovia to got out and buy a VAT of acid and just pour it straight onto his patio (although you never know :;): )

I would have expected him to come back to the forum for further advice.

I have used acid on sandstone on numerous occasions with no ill effects, but obviously I know what I am doing.

To anyone out there thinking of using acid on sandstone, always take professional advice first

Not sure exactly what it is but its definately sandstone from the Kota region of India. Before I give any further advice on how to remove the cement can you post a photo of the affected stone?

As I said in an earlier answer, get in touch with a company called Tensid do a google search for their details, and ask if they can send you a sample of there Limestone restorer.
