Antiquing brushes as Stu suggested is the way to go you may want to try to clean and then brush depending on what you can charge.It looks like soft and very absorbent limestone so i will suggest to go with Densifier maybe even twice before sealer. Best way would be in my opinion to clean it first with alkaline cleaner and brush, neutralize it, densified, hone with antiquing brushes somewhere at 80gr, clean slurry, densified, honed with 150gr brush, clean slurry, finish with 500gr dry to get nice patina and seal it with impregnating sealer.On Thu, Nov 30, 2017 at 10:39 AM, Stuart Rosen <mail@stoneshine.com> wrote:Agree with Fred-testing is needed but grit brushes may be the way to go.We refinish brushed,antiqued,leather and textured surfaces for our clients .Brushes are always the key-It may just clean up with some good scrubbing. Its possible you could even refinish before the installation or just refinish it after the install to correct any potential grout residue issues.--On Thu, Nov 30, 2017 at 7:49 AM, Fred Hueston <fhueston@gmail.com> wrote:TonyI would first try scrubbing with an alkaline cleaner and see what will come off.

It was removed from an 18th century home, they want to use it in part of there new home. It originally was a cream color. It is now a yellow dirt color. It is very textured. Would appreciate any ideas on restoring.It may have some coats of sealer from many years ago. thanks
