Patching concrete problem

[Tommi Bauer]

I have a hole to patch outside of my house, it's not a small one. Basically it is the hole where the metal electrical meter box outside going through the bricks into the basement fuse box.

I bought this Dap Ready-mixed concrete patch

After waiting for 10 hours, this morning I see cracks on the concrete.... is it normal? should I just apply 2nd/3rd coat? or did I bought the wrong product?? and need to redo it? help.........

How large is "not small"? Did you rtfl?

[Tommi Bauer]

It is like a 4 inch dryer vent, but in the middle there is a 2" - 2.5" dia. PVC/ABS electrical pipe going through.. so I am filling the gap around that. I didn't use any wire mesh.. so, what should I do now?

What is rtfl?

I've used hydrauloc cememt like Damit and it worked well to patch a hole but may be dark.

I was thinking the same thing. Hydraulic cement is kind of pricey, but it works great. So you may spend $10 on that hole, but it will last forever.
