Hi
I am pressure washing indian sandstone today but the landscapers previously swept in a dry mix of sand and cement. So the faces are all cloudy

Thought the 'travertiners' on here might no something to strip it back. Thinking maybe acid rinse

Cheers

Pop down to your local tile shop, they will probably have some Lithofin Cement Away.

Pre wet the Sandstone then flick over the face of the stone with a Mono Rotary machine fitted with with a Silicone Carbide brush and some Honing Powder to get the haze off.  Don't use acid as you will make it worse and etch the face of the SS which in turn will mean it gets dirtier quicker.  When your done seal it with a good quality impregnator sealer.  Don't use Lithofin Cement Away either as that will also etch the surface.

I thought I had better check if I had given you some bad information, so,I "googled" Lithofin cement away...
There is nothing on their web site to suggest that you cannot use it on sandstone, I have used it many times and not managed to etch the surface, how anyone can etch sandstone is beyond me, however, I use brushes all the time on such surfaces, they are brilliant and pleased to see that they are now being recommended as a first choice to sort this type of situation.

Clarkson, try Lithofin Builders Clean. It is not as aggressive as Cement Away

[Floor_Tony]

So rob now you have suggested two types of acids now you may have not had etching on sandstone but do you think you have given the best advice there if the person takes your advice to then find out the sandstone is acid sensitive.

Or is this all more jibes and after another argument just like the other forums aye!

Cement Away should not be used on any stone that is acid sensitive or any stone that acid could affect.  To a degree you are right that In general most but not all sandstone is not affected by acid.  However because I am ultra careful when we restore stone the fact  it is sedimentary means acid can or could cause other problems e.g. Iron additionally it can also contribute to speed up the fading process.  So with this knowledge I don't take any risks hence the reason for my recommended method of the honing Powder.  As for your little quip regarding the brushes I have always recommended brushes but only when they are appropriate.

Well, after yet another clevering (again) from the people who only offer advice by phone...it would appear that Lithofin have got it all wrong!! As we are all aware, Indian Sandstone CAN be cleaned with either of the products made by lithofin....ring them, they will tell you and I should know because I have used it in the past, now I choose to use Lantania products, they have an acid detergent which would also do the job.

I am not rising to your childish quips Tony. Please grow up!

Good to see you recommending brushes though Kevin...much better than nasty chemicals aren't they?

As for Honing Powder on Indian Sandstone...you are having a laugh aren't you?? What a waste of time and money.

[SteveAllan]

What are those brushes like on Porcelain Rob. I have a job where some loon has covered a porcelain floor in lithofin slate seal.

In all honesty Steve, I have not tried it, my work tends to be stone. If I can think on, I will get some porcelain and blather a load of Slate Seal on it and give it a go and let you know.
Who in their right mind would put SS on Porcelain?

I may be wrong (I am sure SOMEONE will let me know if I am!!) but....won't WAX OFF remove it?
(Get ready for the abuse.... )

The funny thing is Rob I went to look at the job today and a tile doctor had been in before me and told custy it was slate lol. 32sqm and told her she has to move out for 3 days while 3 guys remove it. She was put off by his price lol.

just been checking the other forums and I see no arguments...give me a clue please?

[SteveAllan]

Chill Rob, think happy thoughts, all is good with the world

Yeah, you are right Steve...just wondered where he thinks I have been arguing?? I just can't do right for doing wrong can I? I recommend one of their products with no thanks at all...then they go off on one 'cos I try and help out with a slight problem...what is wrong with them...they want to start an argument....well, I am not lowering myself to their childish levels.
