We have ALWAYS applied a 10 mil low viscosity epoxy primer first, then apply an epoxy intermediate coat (10 mils), broadcast flake into it, then apply 10 mil polyaspartic topcoat. This has been the system we have installed for 28 years without fail. Diamond grinding must be done as preparation...

I agree 100%. We have done the same repairs in parking decks. Saw cut the perimeter, chip 1 1/2 - 2 inches around and under the rebar, sandblast the rebar, apply Sika Armatech 110 epocem to the rebar, apply epoxy bonding agent to entire repair and pour high-strength mortar. Somebody mentioned...

There is no argument, I believe that's what I said already.

I agree with Alpha, remove and replace would most likely be the best option for the apron at least. Any patch is only as good as what its bonded to and it doesn't look very good as far as substrate condition goes.

I would always recommend using epoxy and or polyurea repair materials. The bond strength is far superior to any cement based products, especially if the concrete condition is questionable. I would also recommend using a penetrating epoxy / polyurea to repair cracks as opposed to topical gel...

It is always recommended to diamond grind concrete prior to installing any coatings. Even if it is a new concrete slab, the scratch created by diamonds create a mechanical profile for epoxy or polyaspartic to bond to. Mechanical preparation is always the recommended method. I have always...
