An alternative to scarifying.
An alternative to scarifying.
(OP)
I've got a job where the detail I am using asks the contractor to scarify the top 1" of a concrete pad (before the application of an epoxy grout). I was wondering: rather than the labor involved with doing that, why not [as an alternative] use some type of embedded form that would achieve the same thing? It seems like (some years back) I saw something like this. It was sort of like a plastic grid deal that had an edge sort of like a saw tooth or something......except that the "teeth" were kind of square.
Has anyone seen something like that or can recommend a good alternative?

BlastTrac works very well for this. It is easy to use, relatively clean and provides a good profile for epoxy toppings.

I always thought BlastTrac produced a smooth surface.....will look into it more.

One thing that concerns me with that amplitude is: you are going to have chips/debris lying around everywhere.......and if the contractor doesn't clean/sweep it off good, your grout will bond to debris (which is obviously not desired). So that's what prompted my question (i.e. a non-destructive way to get that).
