I am looking into a fiber additive for my small indoor. I currently have concrete sand with a bit of limestone stondust as footing. It is thin and I need more sand. Before purchasing sand, I am trying to decide on a fiber or other additive. It seems that most of these fibers recommend a finer, subangular sand (and I think mine is a fairly coarse, angular sand).
Has anyone compared FutureTrack to TruTex? They seem very similar, and I think they are two of the more affordable footings. Also, any input on what type of sands work best with these fibers from experience? My current sand packs fairly easily, but is very stable and otherwise nice footing. I am considering a masonry sand, which I think would be a bit finer than the concrete sand I typically purchase.
I welcome any advice. Thanks!
