Hi All
I am very much hoping someone can save my patio.
Last year we undertook a fairly substantial task (for an office bod) laying a large patio (circa 70m2)... this all went well until my Father in Law and Wife decided they were going to point it up one weekend while i i was away. It was a sterling effort and i was surprised they did it so quickly (1 day)....
Essentially i have been left with Mortar everywhere and multiple smears across the entire area... i have tried just about everything (acid on a small patch, pressure wash, wire brush) and am now thinking about sandblasting to get it back to basics and then re point.
Is sandblasting an option - the slabs are sandstone (Natural England from Travis Perkins)
Any thoughts or suggestions very much appreciated
I will upload some images when i work out how..
Dom
Did i really let this happen!!! - Father in law + pointing = pain

Pics would help.
you need to upload them to a photobucket site or the like, then lost a link to them.
Do you know what mix they used? What sand, what type of cement? They didnt brush it in and hose it off did they?

Here we go - hope this works
NO they didn't brush it in thank god
Being fair i have to say both my Wife and Father are very practical and have built all kinds of things (walls, buildings, etc) i just think this was a job requiring patience and detail and thats not their besyt trait.
The mix was something like 3 sand, 1 white cement and 1 lime
Thanks for your help folks

Dom's photies.....
Trying to clean mortar stains such as these with acid is fraught with problems. The *whole* of the flagstone has to be cleaned, not just the stains; the acid may well cause permanent damage to the stone; it will quite likely need several treatments; it may not get rid of every mark; and it may well leve a residual stain where other salts from the mortar have penetrated the sandstone.
When I do my professional assessments for the courts, faced with such an eyesore, I would normally recommend outright replacement. I only usually suggest sand/grit blasting when it's an expensive/hard-to-source/treasured stone because it brings problems of its own, not least of which is the bloody mess (and the cost!)

Thank you Tony
ok so this is an official nightmare!! I cant afford to do a complete replacement - it would cost a fortune
If i was to try acid what product would be best to use?
Would i then need to seal it - again what product would be best?
Please can elaborate on the challenges of grit blasting - do you think it might break the slabs as sandstone?

Thanks Sean
I have had a quick go attaching a wire brush to a drill head and that kind of worked but left some damage to the slab
Can you suggest a type of pad?
Sorry for asking but i am not familiar with these products
Starting a feel like there is now way to sort this...

Morning Dom,
Brick Acid should take it off but it could cause further damage to the Natural Stone so avoid that. You could solve your first problem but create another with equally unattractive results.
We make a Mortar Stain Remover designed for removing excess mortar; with some hard work and elbow grease it will help to remove it
http://www.azpects.co.uk/product....er.aspx
We make sealers also but I'd recommend you're completely happy with your clean up job before proceeding with any sealing
If you'd like some advice from our technical team, you're welcome to give us a call on 01473 760777
