I imagine one or two of you had no idea what a power trowel finish was, as I did..
This is the finish on most of our new contstruction.
I use my spinner and wand at about 600 psi. When I go lower I don't think there is enough water to flush it as well with the crappy vac these tools have. The spinner I sometimes turn up to 800. It can cause some streaking but the follow up with the wand blends it all together.
I would just use water and spot clean stains or a light Prespray overall then just water.
Haha must've been this thread.
klenstone would work wonders, keep away from glass and metal
