Need Help with Old Kitchen Stone

Submitted to Community Café

Hi Everyone!

As you may already know, I first started in this group while re-doing my fathers home while he was in the hospital. Now that he is feeling alot better, He mentioned about repainting the old kitchen stone backsplash. (30yr old stone)

I told him I would ask for opinions/suggestions/ideas on Creators Studio because I feel the most comfortable here :)

I uploaded 2 photos of the current kitchen stone backplash. The current "beige" color was painted by my mother who is no longer with us.

I was thinking of doing 2 or 3 different shades of tan/white/beige/grey, something along those lines.

HOWEVER.....  what is my best option for even starting a project like this???

It's impossible to tape off each stone, but do I need to or should I add grout in between the stone or does that not even matter at this  point? I just want my dad's kitchen to look different, brighter, and bigger : )

Any help or feedfack will truly mean so much

Thank you all <3
