Cleaning Yorkshire stone floor

[trevorbayliss]

I am going to uncover a stone floor laid in a living room I am working on. It has been laid on a normal joisted and boarded floor and is 140 yrs old I think (as old as the house). Its been covered in carpet for as long as ive owned it.

So I want to clean it, and not sure how to start. There are some cement infills in places so I want to scrub these off.

Any ideas on where I start. Thinking I need to use my angle grinder and a special abrasive disc to shift some much, cement etc. Then I need to do a clean, but not sure what product to use. Then a sealant. I am ok with the sealant to use, just not got an idea on how to clean the stones up.

Ive seen a tube vid of a guy using an angle grinder and a diamond polish disc which sort of sands the top of the stone down. Then he uses a finer disc on his orbital sander to polish the stone up. Not sure what products he used as no links in the video.

Whilst an angle grinder will be affective, it will leave ugly 'modern' conspicuous marks on the slabs. There's no going back once you hit it.

Would these discs be any good ?

Abracs Poly Abrasive Disc

Attach this poly abrasive disc to your angle grinder tool to remove surface imperfection from your material. The Abracs disc can be used on a wide range of materials such as metal, concrete, stainless steel and aluminium. The synthetic resin coating clings to rust, paint and other contaminants...

I think I would approach a concrete grinding contractor and see what they say. The stone will likely be softer than the concrete, and a DIY grind I suspect will look hideous with circular grind marks if you try and hand-hold. The kit for concrete floor grinding is specialised
