Ask him to lend you his, im not convinced, the products dave has suggested are the way to go in my opinion, I really hope you manage to get it sorted mate, it would be tragic if that was ruined after your hard work.

Have you asked him to come and clean it for you as he gave you the wrong info save you having to do it all yourself

hi there.

i have a similar issue, although nowhere near as badly stained.
going to try the products Dave suggested (how did you get on with those btw?)

also wondered if anyone could recommend a good sealer for black limestone - there are plenty on offer but i'm sure some are much better than others.

thanks..

I really wish people would post the results.... You read all the suggestions but never find out the outcome!

Your going to need a ph neutral cleaner, you can get them from Amazon a stiff broom and don’t use mortar to fill the joints, use something called easy joint, it’s between £30-40 per tub, sets with water.
But all of this apart from the jointing needs to be done in a couple of weeks.
Wet the Slavs before laying them too as it helps stop muck from getting in.
But it’s just going to take a good scrub wit a PH NEUTRAL cleaner.

As a stone practitioner, I suggest that limestone should not be sealed or cleaned with alkaline materials. You can refer to this article.
