 You sand in between, but it's not like you got to get out the sander. It's a sanding sponge that they put in there. So you're just kind of knocking that down a little bit. And on the spread stone, there's actually some mineral in there, which will add a little bling to it. So I would say light sanding with the sanding sponge is all you're going to need. And again, if you go on their website, they got some great videos on the whole application process.
