precast garndstand bleacher finish
(OP)
What type of surface finish should we specify for the top surface of precast stepped grandstand, that will be smooth enough to be able to be kept clean, but not so smooth as to be slippery when wet? The grandstand is in Ontario, open air, and not used in winter, and there is only a crawl space below. Is there any standard top surface finish that is normally specified for this?

Have you ever heard of casting the bleacher slab upside down and then treating the formed surface so that it is not so slippery (perhaps with an acid as you suggest)? I think that is what may have done at the Rogers Centre, but I am not sure.
Must be a lot of precast bleachers around. Anyone know what is usually done?

I have not seen bleacher seats cast with a rough finish on the walking surface. I've load tested and inspected lots of them and as I recall, the surface texture is an add-on of some sort (even the 3M adhesive grit strips have been used). I've seen many with no surface treatment. Weathering takes care of it.

Rinse well when done.

I spoke to the precaster and he says what thye do in their precast arenas is a broom finish.
RE: precast garndstand bleacher finish
(The big question is interior or exterior exposure.)
Usually exterior is broom finished,
and interior is a no line float finish ( not a hard trowel)
In my opinion coatings usually do not hold up for the long term.
The Architect should dictate the finish with guidance from the local precast providers. If they can't / don't want to provide what the Architect wants then a coating is a option.
