Indian Sandstone Picture Framing/Grout marks

[Bill]

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

Polythene and tape up aluminium rails, work in small areas 1 metre x 1 metre and adhere to instructions on bottle and it will turn out spot on how it should have looked. Only advice is the weather don’t do it early morning now for frost and try and get a 2 or 3 day good dry forecast
Also yes Lithofin cement away, a local tile shop probably stocks it

Thanks callatiler. If it splashes or flicks up will it burn through the polythene, on to the Ali track/glass? I’m so paranoid about ruining this. Same as how close it is to the new glass doors.

I’ll do a test area first too

 

[Blunt Tool]

No any splashes can be rinsed with clean water right away work methodically and you will see good results
Won’t burn thru polythenes it’s not sulphuric Or the stuff that comes out of aliens haha

Oh Jesus I’m going to be crapping myself doing this!

Just out of curiousity - what’s the difference between the lithofin cement away & the builders clean?

Should I use neat or ??

No use Lithofin and a 1 litre bottle can be diluted with 20 litres of clean water do not use neat. I would personally get a clean 10 litre bucket and add 100ml of cleaner and mix, then I would have 3 buckets of clean water beside me

Acid is ok with plastics..... look at what acid is stored in.......

I laid Indian sandstone in my back garden last year...........they definitely need sealing. Can’t remember what sealant I used, but the instructions said, it needed 5 clear dry days before sealing. Then I used Wickes own brush in pointing.......which was horrible stuff.......but it looked ok when done.

Ultrascape is a wet grout and is supposed to go all over the slabs too. Other products differ.
