Trump specifically bragged about both sand blasting and pebble blasting, though I have no idea if that's standard procedure.
From a laymans perspective, seems like that's to clear off debris / surface grime and grit. Adequate cleanup would need to happen ontop of the surface prep.
It however would do fuck all about the water that's soaked past the surface and much deeper into the stone. NFI how long that would take.
For perspective I've spray painted some things, laid some bricks, grouted' some outlets into walls and have no career or formal education in those fields.
