Bonded Topping Horiz and Vert Surfaces
Bonded Topping Horiz and Vert Surfaces
(OP)
I'm hydroblasting a portion of concrete slab and wall to apply a Sika 123 or 122 topping. I'm also providing a WWM reinforcing. I've normally secured the mesh to the concrete using Hilti PAF. Does anyone have an alternative method of securing the WWM in place?

I have no confidence that it can be held in place vertically in a horizontal pour unless you intend it to end up at the bottom of the pour. We typically require chairs for this purpose, but somehow the WWF always gets smashed into the subgrade in the case of slabs on grade.
If you want to maintain horizontal position in a horizontal pour, you could simply install nails or screws into the concrete in some rectangular pattern to act as vertical "pegs" to keep it from sliding around.
