Bluestone or blue stone surfacing. Etching or blasting?

14 years ago

Hi all. I got a question about bluestone. i recently purchased a bunch of bluestone an installed a rather nice sidewalk an multiple steps. The steps had to be cut different depth sizes. some where 10.5" deep, an others where 11.25" deep etc...

By buying large pieces of bluestone, an cutting the steps myself, i saved well over 50%. I doubled my square footage for the price. An my steps where all not the same depth, so i would of had to cut a Precut tread/step anyways.

Example- it was $54 for a precut tread/step that was 1.5" thick an 12"deep x 48 wide". it was $54 for a standard 1.5" thick that was .....24" deep x 48" wide. 2 for 1. 8 stairs

The tops of the bluestone are etched or have a sandblasted " rough look " , basically a random pitting look. this pitting gives it traction an also removes or de-glazes any cut marks from when it was processed. These cuts are smooth an polished from the diamond blade cutting through.

I want to pit, or de glaze these cut marks so they match the top layer.

now i tried muriatic acid on a scrap piece. i did not dilute the solution. i let it sit for 30 mins, rinsed an dried. it looks almost the same an appears to have not pitted the surface.

SO, at the quarrys , do they sand blast the surface with reclaimed blue stone pieces, or some other material? or do they use an acid like one would use for etching??

Was also thinking of power washing maybe??

I've searched the internet for about 3 hrs now an have found nothing at this point that states any of this surfacing method. Anyone have any ideas???

Im handy an ready by any an all means to do what is necessary. I hate looking at the smooth cut surfaces.

Thank you in advance...
