my granite was installed and sealed. it is 4 yrs old and we have never "resealed"it because some people say its not good for the stone. but lately it feels more gritty and porous. can it be buffed shiny and smooth?
I should correct myself… its not a residue…its very clean . its more like pitts in the stone not deep or anything but areas where the smoothness have worn down to gritty feeling areas. would sealing help this or polishing?
