I live in Puerto Rico and many of our houses have concrete roofs. Many were built before epoxy coated rebar was available and built using beach sand so yeah, this is a very common repair we have to do around here. You did an excellent job! I would add to use concrete bonding agent and, you could substitute rust oleum with phosphoric acid of some sort to treat the rust. As you mentioned on the caption, one MUST treat any leaks and seal the roof beforehand otherwise, all that work be soon for nothing. Great video!
I am in old san juan. I have leaks in roof and exposed rebar. What would you suggest? I do have a contractor, but i want to make sure he does all the necessary steps.
@@michaelk906 Hello, It all depends how bad your damage is. I would get an engineer or contractor define if the roof is repairable. I've seen some roofs that are simply too far gone. I hope that's not your case. Anyhow, the 1st thing I did in my case is control the leaks and the spots where water accumulated. I did a complete stripping of multiple coats of different sealants that were on, level the low spots with self-leveling cement, treated the roof with a good primer and applied 3 heavy coats of Lanco Urethanizer, allowing a few days in between coats. I really like that product and holds up way better than the usual silicon elastometric products. It shold last at least 5 years (with a yearly pressure washing and spot checking). Sealing your roof is essential as it will prevent humidity from making the rust issue worse of course. Once that is taken care of, you can allow your roof to 'dry up' and then you can tackle the exposed rebar as I mentioned on my previous post. 1. chip away loose rust and cement and appy 'Klean Strip Metal and Concrete Prep' (phosphoric acid basically). It will convert the rust into a good base for paint and cement and also prep the surrounding cement 2. use cement bonding agent and apply cement. If the holes are big/deep, do it in various coats, allowing 15-20 minutes to an hour to allow it to harden up between coats. If you do it too thick, the whole patch may fall off. As I said, this is a very common repair here in PR. If your contractor is competent, he should recommend a similar approach. Again, stopping the leaks is 1st priority. Best of luck!
@@Fred82ndAbn one more question if I may. In old san juan , I have a 3 story small commercial property. There are existing stairs to second floor on back of property- 65 feet towards back. (have to walk thru the existing retail shop).Now i want to make the 2nd floor a residential apartment , so I want to make stairs from the front entrance of building to second floor, as I'm planning on making a residential apartment. Will I cause a structural issue by building stairs and breaking a hole in 2nd floor ceiling? I'm not going to touch any of the load bearing beams.
@@michaelk906 Sorry, I'm not a civil engineer but I imagine a contractor would be able to tell you if it would be possible. It may need a reinforcing wall or column to bear the load left by the hole and also hold the new stairs.

I live in Mexico, and somehow my landlord believes that because I live in the house, any restoration or repairs are my responsibility, even when these are caused by bad maintenance. Lots of landlords here seem to think that way. But since moving to another house can bring another set of problems, and maybe an even worse landlord, I've decided to take the loss, and just fix what needs to be fixed. My rent is on the lower side, and I'm hoping to live here for a while, as well as possibly buy the house somewhere down the line, so it's a matter of choosing the lesser of two bad situations. It could always be worse! Anyway, I had this happen in one of the rooms. A big chunk fell off the ceiling, and upon further inspection, it has happened before, because the places with cracks have been patched up with something you'd use to patch cracks in walls. Not suitable for the job! So I am really happy to have found this channel and this video, because now I can fix this and I don't have to hire a contractor who will undoubtedly charge me an arm and a leg, and possibly not do a great job either. THANK YOU! I do have some questions. The issues are in our living room, right beneath one of the bed rooms, close to the windows. So it makes sense that it's there, since this would be close to the outdoors. Our roof was recently treated (after we had water falling down the ceiling above the stairs, which indicated a leak in the roof). But this issue is probably due to issues in the outer wall, right? So how would we treat the wall? Is there anything I can do for this?
So glad I found your video. It was exactly what I needed. At my old age I was able to do it following your instructions carefully. Perfectly explained. Mine was pretty close to being as good as yours . Didn't use bonds. Use whit glue because I couldn't afford that large container and then would have to discard. Thank you
I am just doing this job in my garage. Luckily I have a compressor and needle gun. Saved me a Lot of time ! Turned out to be in better condition than I expected too. Seems I am on the right track and what I had planned is near identical to what you have done :)
@@electronicsNmore I thought it is a good idea(depending on distance to a water body or altitude) to have a bunker in Florida for hurricane season comes. I am near Chicago so it would be great here as well.
Nice repair but wouldn't the first thing you do is find out how the water is getting in to corrode that rebar to start with?? I would think stopping that problem would be your #1 issue.
if the rebar is rusting the whole shit is completely fucked and won't last much longer. that patch is literally just that, a bandaid patch. even if he stopped the leak it'll continue to rust out
It will be ok for the next five years. Enough of time to sell the house. 😂 I understand the idea of chipping away the concrete to the rebar and make sure the rebar outside of the spalling area is free of rust. Then repair.
Cured concrete will not bond with newly added concrete. It will always crack and separate. Sometimes when you pour a couple of inches over old concrete, the weight of the new concrete keeps them together. But, if water manages to get between the layers, it will eventually cause damage (particularly if it can freeze.) Laytex bonding agents (as used in the video), and other types too, provide the interface, between the layers, to bond them together. It is easy to use, and makes a very strong bond.
Hello, thank you for this super helpful how to. I'm renovating a condo with a concrete ceiling. We removed a popcorn coating and now want to seal the concrete to protect it and keep concrete dust from continuing to fall. The ceiling is in good condition, it was cast in place and has "beams" cast into the concrete, so it's not a completely flat surface (meaning we'll need to do some brush work to apply the coating, as we'll be unable to use a spray application.) I am wondering if you can suggest a product that is compatible with use on a ceiling and help us reduce brush marks during application? Appreciate your time!

I did same job . I mixed about 50% cement and 50% quartz sand , water with 15% impregnation/ bonding adhesive , but i made thick liquid , and with a brush i brushed thoroughly whole repair area . Then after this cement milk penetrated and bonded to old concrete and rusted reebar , aprox 1 hour later i made same mixture but this time paste consistency and filed the crack with it .

What type of cement?
@electronicsNmore I have this same question. Is it just a regular mortar mix? Stucco? Fast drying concrete? What?
Question, I have an outdoor staircase where this has happened, would you do the same process- Thank You

mortar/stucco mix

What type of mortar do you suggest for overhead exterior repair?
Mortar stucco mix
what type of cement you used and recommend for this sort of repair jobs please?

Good job on the repair. Question, is that room a bunker?
It's a concrete block room that's connected to the back wall of a concrete block home.

Looks like every condo balcony in south Florida.
and hopefully not more foundation columns.....
Yes, very common in South Florida.
Thank youuuu
You're welcome!
Brand of cement?
@@jornlazatin8631 Any masonry / stucco mix will work.
I'd use Extend Rust Treatment Spray prior to the Rust-Oleum; just my experience with both light and heavy rust. All else well done.👍

Very god
How long does the repair last?
When done properly, and you also make sure no water can seep in from above, it will last years.
I had handyman did that job on a ceiling, lasted maybe a year. Next time I will DIY.
Wouldn't it be better to chip the concrete past the rebar to make sure the new cement adheres and is help by it?
Just remove all loose concrete.
Cured concrete will not bond with newly added concrete. It will always crack and separate. Sometimes when you pour a couple of inches over old concrete, the weight of the new concrete keeps them together. But, if water manages to get between the layers, it will eventually cause damage (particularly if it can freeze.)

You need sika voh
Rebar can be corroded in continuous segments that are no exposed yet.

Never had to do that.
Just make sure you use zinc paint to neutralize the rusting
Finally. English speaking video.
this what i would have done.drill into cement put anchors in and attach hardware colth,,1/4 in wire net to anchors screws,,then cemet,,using Rock tite
In the past I've drilled in tapcons to act as anchors.
After 3 to 4 month the cent joint is removed automatically
Just keep repairing them properly like that, and you will be rewarded with pancakes in the mourning.
It is stupid not to give the mix ingredients for the mortar!!
