I just finished troweling the vermiculite for for my ig vinyl liner pool. It still has some high spots that need to be knocked down and some low spots to be fill but overall I am happy with the way it turned out. My only concern is that the surface is kind of rough to the touch. Is this normal or is it supposed to be smooth like regular concrete? I was thinking about using an orbital sander to smooth it out a bit. Has anyone tried this or is it not necessary? Thanks in advance for any help.
