To repair deeper concrete defects or to replace missing pieces of concrete, simply add small stones to the mixture. The proportion should be three parts of stone, two parts of sand and 1.5 parts of portland cement for a strong mix. Always use cement paint to bond new to old concrete. Now, once it dries, you can paint it.
And what I would look for is an epoxy floor paint. I like epoxy paints because they are chemical healing. When you buy the floor paint, you get the paint in a gallon can that is about three-quarters filled and then a quart of hardener. You mix them, stir them and then apply the paint.
Sometimes, there is an additive that comes in after the fact that it gives the floor some texture, helps to hide dirt. But patching it first and then adding an epoxy paint will make it look like new in no time. Wondering how to fix a crumbling concrete driveway? Here's some information that can help you decide.

Professionals describe this condition as “chipping.” Chipping is not really a condition that lends itself to D, I, Y repairs. However, if the damage is not too serious, you may be able to handle the repair yourself. You'll end up with a good enough result, but it probably lacks the look that a professional would produce. If your driveway has been severely affected by flaking, which has led to cracks throughout its depth, it may be wise to appoint a professional to carry out the necessary repairs.
In any case, it's your drive, so ultimately, it's up to you to decide. If you decide to undertake the work yourself, here's what you need to do. Temperature is the most important thing and you need to ensure that the air temperature remains above 10 degrees Celsius or 50 Fahrenheit for at least eight hours after the concrete has been poured. After that, the temperature should remain above 0 degrees Celsius or 32 Fahrenheit for the next 24 hours.

The crumbling of concrete is not only unsightly, but can also be a sign of serious damage under the structure. However, if these joints were never sealed, or if the old sealant has hardened, crumbled or separated from concrete at some points, the joints cannot do their job.
