I have about 25' of sidewalk on the side of my house that either the builder or previous owner(most likely previous owner) poured the concrete and used the stamp the wrong way and I don't like the look of it. What concrete should I use to cover this up? I have power-washed all the moss off it yesterday. See Pic.

 

That is the quickrete mold for making walkways.

Unfortunately there is no patching that will stand the test of time, concrete is not easily patchable. They make some patching materials, even epoxy based, but they are more for interior use. Put them outside and eventually they will fail!

 

It would have looked nice if they used it correctly... I have to try something.

 

Yea, it looks a bit like poor man's stamped concrete. Unfortunately I think the best option is to remove the walk and re-pour. A lower cost option would be to glue outdoor carpeting on top but once you do that you're sorta committed to stay with carpet as the glue can be very difficult to remove.

 

The stamping is deep so I'm going to try pouring some over it and see how it holds up. What cement should I use?

 

Look into topping mixes. A year ago I was looking at options to repair a damaged slab. One of the things I looked at was using a topping mix for an overlay. We decided to go in a different direction but I did the research and I found that there are some topping mixes that contain bonding agents and there are many that do not. The most popular brand does not but they do sell a bonding agent. I think the one most recommended was a Canadian product.

In any case, outside of labor you don't have much to lose. Topping mixes are relatively inexpensive. If you choose to go that way you should plan on at least 1"-2" on top of the existing walk.

 

I have used fortified topping products. Because of the rapid curing time I found it handy to have two people. One person is the mixer and the other the spreader. That way while one person is spreading the first batch the other is mixing the next batch so you can get the next mix down before the previous has cured too much to avoid a cold edge.

 

Ordinary cement/mortar will probably fail. I learned that the hard way years ago. A product fortified with a bonding additive is needed. Google "resurfacing concrete" you'll get lots of tips regarding products and application.

I agree that putting an overlay on your sidewalk is probably a 2 person job.

 

OK, this is just a shot in the dark, But have you considered a grout to fill in the spaces.

 

I want the mess gone. It looks bad to me. I should have torn it up and continue the pavers I laid when I did the driveway.
