Indian Sandstone Picture Framing/Grout marks

[Bill]

I have stated that the contractors didnt use a wet mix like they should have but you said it should be a dry mix, which is wrong for ultrascape.

My advice is correct.

Yes Tom that’s right, I’ve got the spare bag here. Obviously when the landscapers did the job, and told me it’s a dry mix, and I watched them brushed it in dry (then wet it after) I very naively presumed that was how a ‘dry mix’ was used. They should have followed the video!

Nevertheless, I’m trying to rectify the mess now.What do you think about the Lithofin Tom?

semantics, pragmatics and stubbornness abound!

Cement away

that's acid based, is this sandstone acid resident?

I don’t know but doubt it?

I don’t know but doubt it?

if you try an acid based cleaner as advised do it on an off cut first. I would try builders clean or power clean first

I have cleaned my own sandstone paving with mortar remover after having an extension built but this was more localised areas rather than the whole thing.
I put the cleaner in a bucket and used a scrubbing brush dipped in the cleaner and washed down with plenty of water.
I sealed after with a colour restorer/sealer.
It didn’t damage the stone in my case but then mine were not covered like yours.

I’ll order some today, do a test patch & come back with an update. Wish me luck!
