Dear Sir, We are presently using tenex epoxy on black lime stone and getting the stone for high glazed polished (which looks like absolute black granite). Since it is soft material, after lying and used it get scratches up very soon. Kindly suggest us if there is any liquid for application to control the scratches and also making it as stain proof. Your prompt reply is very much appreciated.

 

Dear Sir:

Unfortunately I don't have an answer to your quest for such a special sealer that will turn limestone into granite.

However, you may try with NASA: I understand that the rover they sent on the latest mission on Mars came back with some interesting sealer from the red planet. Some sort of liquid diamond or something!...

Ciao and good luck,
