Anybody got an urgent solution

[Cranbrook]

My grandfather in law has recently finished a limestone job (pictured) and tried cleaning the stone with brick acid prior to sealing... He's in desperate need of a solution so if anyone knows a solution I'll be grateful to hear them

Erm. He's killed it.
Good news is there is a product that will fix it.
Bad news - I forgot the name of it.
Bare with me....

Easyseal back to black.
(It has ruffled a few feathers in the world of sealers I'm told)

I'd suggest a really good wash before using it though, and make sure everything is dry.

Thank you mate.. I may well become the favourite man in the family thanks to you

Maybe LTP Blackstone.

Trust me on this, there's no better product for this one. I can't say how I know, but I know!
(this product has been tested by rather miffed sealant companies who are going to copy it)

Isn’t that meant for car body trim?

For all I know it could be the same!
I used to use loads on my yokohama a520s on my old pug 205.

I just sent him the good news but he's worried that the limestone he's laid is grey....

 

[One Day]

Well I don't know then! He's basically bleached the dark pigments away.

I would call Bob at lithofin. He's the total expert in this.

Looking at the videos and how it restores acid marked stone it does look good.

Whatever he uses do a test area first.
Not like he has already done with the brick acid!!

Limestone is alkali. Acid will dissolve it and the grout.
Call Lithofin

 

[One Day]

Limestone is actually pH neutral dissolved in water, but it is an alkaline agent.
The acid used had released /created calcium salts.

(that's technical for "he gone done goofed")

 

[Huddersfield Tiling]

Limestone is mainly composed of Calcium Carbonate which has a pH of nearly 10 which makes it towards the high end of alkaline (14 being the maximum). Even weak acid solutions will cause a dissolving action, and even something like cola which is acidic can dissolve and stain the surface. Without an impregnating sealer, limestone remains vulnerable to any weak acid solutions over time (including acid rain in areas of high pollution).

I'm not arguing
