Repairing concrete

[RickH]

I have a small. Strip of concrete that garage door has damaged …and also concrete fence posts on a few there face has spalled exposing rusty reinforcing.

Anybody used a concrete ‘patch/repair’ paste … is this one any good ? or do you know of better.
On posts, I will use rust converter to try and help in repair

Never used that product but I would imagine the success will depend on the preparation and thickness applied. You could also use it on the post but would think it would only be a short term measure once rebar has started to corrode. A pic of the 2 might help get more advice.

It's probably pointless messing about, once they're falling apart you're not going to halt it, they're presumably a few decades old. Fence posts are cheap.

Might as well replace the panels too, do the job right.

The posts are 20 years old … and apart from 2 of them spalling ( about 3” x 1/2” ) are fine.

I have used this tub in the past to patch up some brick work and some minor repointing. Will probably not use it again.
- This "beige" is quite beige and very bright. I thought this beige would match my existing 3to1 sand cement mix, but it is way too bright and visually stands out
- Very rich in resin (good thing) but also quite coarse sand/balast. Much more coarse than other repair cement I have used, so if you are looking for a fine smooth finish, that is going to be difficult.

On later projects I switched to the grey version (much less visible) and than later switched to metolux metoset concrete repair resin, which is a lot smoother and comes in a cartridge, so easy applicable. Most work only done last year, so can't really comment on durability of either.

Thanks … I saw that Soudal also sell it by cartridge.
Where did you get this … I have seen a few suppliers, ~£14 including delivery.

yeah I remember searching a while... if you get a pack of 5 or 10 it's ok, but I only needed one. So in the end I bit the bullet and went with amazon £15 quid....

For small cracks or surface damage, try using a concrete patching compound—it’s easy to apply and can really improve the look. But if the damage is deep or structural, you might want to consult a pro.
