Can cracked concrete be repaired?
Wide cracks in concrete are best patched and sealed with a concrete patching compound. Smaller cracks, less than 1/4 inch wide, can be repaired with a concrete caulk or liquid filler. Patching compounds typically are mixed with water and applied with a trowel.
What can you cover cracked concrete with?
Lastly, the most popular way to patch up cracks formed in concrete is with polymer resin. This option is the most expensive DIY option as it not only fills the entire depth of the break but also forms a permanent chemical bond with the concrete slab, gluing the slabs together to seal it from any structural moisture.
How do you fix hairline cracks in concrete?

How much does it cost to repair cracked concrete?
Cracked concrete is the most common issue for homeowners. Concrete driveway crack repair methods depend on the size of the hole. Most contractors charge an average of $2.00 to $2.50 per square foot to apply a filler and sealant to the damaged area.
Can you pour new concrete over old cracked concrete?
There are situations when pouring new concrete isn’t the most suitable option.

Will epoxy fill cracks in concrete?
A. It’s true that neither basic garage floor paint nor an epoxy coating for garage floors fills cracks, but that doesn’t mean you can ‘t patch the cracks and then paint. Epoxy floor coatings, which are more durable than paint, usually come with vinyl chips that make the surface look like it’s scattered with confetti.
Will hairline cracks in concrete get worse?

Should you fix hairline cracks in concrete?
This less evasive crack repair technique breaks the rules for concrete repair. Hairline cracks are not worth the trouble fixing. You have to cut open a hairline crack if you want to actually repair it.
Will concrete sealer fill hairline cracks?
Ideally, the sealer has a low surface tension so it readily wets out the concrete and a low viscosity. These two characteristics allow the liquid sealer to penetrate deeply into the crack. Common concrete countertop topical sealers can be used, but getting them to penetrate and fill a hairline crack can be difficult.
