What are these "stains" Gavin? Is it just moisture or something more sinister? Could it be Reflective Staining?
Post a photie or send one to me and I'll upload on your behalf.

Had a good chat with Gavin on the phone on Thursday, he'll either email some photos over to you Tony or me. Think we know what the problem is, but will wait until the photos before confirming.

Roger, your advise is most appreciated, and what you have to say regards the trapped moisture make perfect sense.
I applied the HD Sealer, following a good review from this web page, and happy there seams a solution to rectify the issue.
Please can I ask your advise regards recommendations for best stripper / sealer to use going forward?
Many thanks Andy

To remove the sealer you'll need Tensid's Tavec 201 which is a coatings remover, but you also need to use steam, so either a Doff or Torik machine.

"Readily available" and "off-the-shelf" are not terms that can easily be applied to *quality* sealant strippers, mainly because they are impressively nasty chemicals - and need to be if they are to be effective.
The seriously good strippers, such as that mentioned by Roger and the Paramose range, are either sold by specialist suppliers or available to order direct from the manufacturer. You'd be very unlikely to find either at Homebase or B&Q.
As for a replacement sealant, look again at Sandstone Sealant Trials

Okay, many thanks for the reply, I will start looking for a sandstone cleaning company this the steam machine.
Following the cleaning - will gladly take advice on what to reseal with?
I have 5L of HD ADseal remaining, but cautious of reusing this due the the problem reoccurring, if indeed the sealer was the problem in the first place?
Any recommend welcome?

Tony,
Apologies, I think we had a slight time difference in above reply, as advised I will revisit the test page to scope a suitable alternative.
Whilst a quick fix was wishful thinking, as always your advice is appreciated.
Andy
