ᐅ Repairing and coating a trowel-finished garage slab foundation

Hello everyone,

We have a power-troweled concrete floor in our garage.
In a few spots, the concrete has chipped off in various sizes, probably due to objects that fell on the floor during construction, such as a hammer or similar.
The holes range from 0.5 cm to 3.5 cm (0.2 to 1.4 inches) in diameter.
My question to you: how can I repair these areas myself so that the floor is as uniformly smooth as the rest? Do you possibly have product recommendations?
I am planning to "paint" or coat the slab to protect it from influences like de-icing salt or similar and also to give it a more uniform appearance. Currently, the concrete looks “spotty,” which seems to be normal.
Here I would like to ask whether a coating is recommended or if it is unnecessary because of the power troweling. What kind of coating would you recommend for a DIY project?

Thanks for your answers.
Good luck, Ippebson

Hello again,

Does no one have experience with this? I was able to find some information in other threads regarding coatings, especially about the 2-component epoxy resin coating, but not about its necessity or requirement for power-troweled concrete floors.
Also, my initial focus is on the topic of repairing damaged areas.

So, let’s get typing!
Good luck

Hello,

I can tell you that we will also be coating our concrete floor (not smoothed) with a two-component resin.

In my opinion, an uncoated floor cannot last forever. Especially because of the salt used in winter, the concrete will start to crack and break up over the next few years.

Hello

use "repair concrete," it hardens like rock.
After that, apply a coating (2-component resin is a good choice) and you will have peace of mind for a long time.

Can anyone provide information on the installation instructions?

Minimum outside temperature and humidity?

Can you recommend a manufacturer or a specific product?
