    Rough Spa Surface

    I've had my in ground pool spa for a few years, but the spa surface is very rough on skin and swimsuits. It's not a chemical, calcium, etc issue. Its been rough since start up. How can I smooth the surface? Can I drain and sand the seating area? If so, any ideas on how?

    Is the surface plain plaster or something else?

    I've sanded small areas before and it works pretty well.

    Re: Rough Spa Surface

    I have used either a pumice stone or wet sand paper. But I am not sure that will work well with a pebble surface. Is it the stones or the plaster making it rough?

    Re: Rough Spa Surface

    I had some 40 sandpaper, so tried it and it is working. Did it by hand of course. Didn't need a lot of pressure either. BTW, spa was empty and dry when I sanded. Not smooth, but MUCH better. Sanding the spa was a request I had made of my builder, but he failed to do a lot of things. I was NOT happy with him! My swimsuit thanks you for your help. Hope this helps others.

    40 grit sandpaper? Isnt that really course? In my plaster pool I smoothed the spa a little but think I was using 200+ grit wet sandpaper. Also might be better to sand it while it is wet/full.
