Concrete stair riser repair

Hello ALL!

As we're thawing from winter... I noticed that the top riser of my concrete stairs leading to my front door have started to crumble a bit. I am assuming that some water has made its way into the concrete, and the freeze/thaw cycle had popped off some of the concrete.

I live in Toronto...so, a pretty similar climate to NY. I was wondering what the best way to repair this riser would be? Would hydraulic cement work? Would that be my best option? I haven't done any masonry work/repair previously... I know I'd have to clean the area, and chip away any loose concrete. Then what do I do? Any products out there that you'd recommend? A process that would be best?

Thanks, and looking forward to your thoughts.

Hello Chromed,

I don't have much personal experience with working with concrete, but I see that no one has replied to your question. Hopefully, someone with real world experience will come along and share his/her advice.

In the meantime, I suggest the following video : https://www.youtube.com/watch?v=Llxg17jOLIU

I did observe a pro repairing a concrete step where I work. One of the key aspects of the repair is to use a bonding agent. The guy in the YouTube video uses a clear or translucent bonding agent. The pro who worked on the step at my workplace used a pink colored bonding agent, which, to me, would be easier to make sure you have full coverage.

Good luck with your repair.

 

I've repaired my steps with the same problem. I used Top and Bond and it seems to work. Don't know if it's the proper stuff or not.

 

Thanks to both of you for the replies! Very much appreciated!

Looks like that top and bond will accomplish the same result as the video. And thanks for the video... that will definitely help.

I will wait for warmer weather, then get cracking on this project.

 

I finally got around to getting this project done. Yes, I know its August...but hey, better late than never!

SturdyNail, I used the video that you posted! It completely helped. I used all the products that were mentioned in the video, just except for the Acrylic Concrete Cure and Sealer...

I first bought the Top'n'Bond, then I read the instructions on the Top'n'Bond... they recommend for gaps less that 2"... these gaps (most of them) were bigger than 2"...

I've included the pic of the final result...just in case stumbles on this thread.
