Sanding a Pool

[skingery]

Great question. I used my orbital sander today but I went with 100 grit and it is working well but also very slow. I am having a hard time deciding how much to sand. Using a sanding block, I can see a noticeable difference. With the orbital, I have a brighter white. I think the brighter white is what I want but I am unsure.

Any advice?

Other than to get a diamond pad? No.

Good luck.
