Sub Poured Muratic Acid On Marble Pavers NOW WHAT ?

Definitely sounds like a plan to bring them out and see what they can do. Spot testing is great. Diamond polishing large areas will be expensive and may add more “swirl” to the pattern than you would like. But if he “knows a guy” with a sand blaster then maybe a combination of the diamond polish to level out the surface followed up with the sand blaster to give it the right texture will do the trick. You may need to do the entire deck (good and bad stones) just to make sure it’s all got the same final finish.

Definitely get options and costs, in writing if possible, and let your PB have a look at it … he’s paying for it!!

Heck yes they are paying for it ! Yes I will get all info in writting . I was planning on whatever is done it will be to the entire decl. Thanks for your feedback !

If the type and size of the blasting material (sand, garnet, glass beads, etc.) are matched to what was done previously, then the walk to success may be short.

In my opinion, sanding/polishing first will give a better result.

Sandblasting tends to create a more uneven surface.

If you sand first, then the sandblasting would only be needed for texture.

Trying to get a uniform surface by sandblasting to remove the surface would tend to create hills and valleys.

Different material but in the machine shop we would always turn and machine metal surfaces to get the desired uniformity and size and then use electro-polishing and/or diamond blasting to create the surface finish we were after. You could never use blasting or electro-polishing to dimensionally “cut” the surface as it would always lead to non-uniformity. I suppose wood working would be similar - use your lathe, router and saws to get the shape you want and your sander to produce the finish you want.

All good info. Looking forward to what the restoration experts say!!

Hmmm. Interesting thought. @JamesW

Remove everything, replace any damaged stone, provide consistent grout lines and provide adequate expansion joints.

Sorry if this is inconvenient to the builder, but you paid good money to have this done exactly right; not some botched ugly nonsense.

Great suggestions , hoping to get the specialist out here to take a look and then will let you know what they say . He was suggesting a path like you have suggested when I spoke with him on the phone.

A lot depends on how deep the damage is.

Sanding won't help if the damage is too deep.

Maybe take some fine sandpaper to a spot and see what effect it has and how deep you have to go to get back to the original finish.

Good idea , he dis say he wanted to spot test an area . It is possibke that sone areas are deeper than others as to the eye some places you can see more damage than others.

Hi , just wanted to give you all an update , the restoration guy should be coming out in the next week, I think the stone is looking worse. The grays are grayer and that white haze does not seem to be getting any better. As I never sealed the stone it seems to get a lot of pollen/tree stains on it and it is not easy to get it off but I am still fighting the good fight. The restoration guy had me do a spot test by getting a bucket of warm water, putting a teaspoon of Dawn in it and then pouring it on one of the gray stones to see if the gray lightened up at all . He had me doing this a few times a day . It looks slightly lighter. I am looking forward to meeting him and getting his take . No word from PB yet on if or how they plan to address. In the meantime I am waiting patiently and blowing through a good bit of my Scotch collection. Hope everyone's week is off to a great start. - Jen

there is a life lesson, here if you will. one cannot refill an empty glass until it has been emptied. So sip and refill. Repeat.
