Best 3-Part Epoxy Patch for Big Concrete Cracks

Epoxy PatchEpoxy Patch is the best three-part concrete crack repair system. This is the patching epoxy that dries 10 times stronger than regular cement. It can be applied to cracks up to 1 inch thick. It creates a 100% waterproof crack repair. You can also use it to fix holes and pitting in concrete, as well as asphalt, wood and metal. This is a resin-hardener-aggregate kit that dries in about one hour and cures in two to a medium gray color.

You have an hour to work with the mixture, which is much longer than other epoxies give you.

Please remember that you have to work within the product guidelines. I have to shake my head at someone blaming the epoxy when they used the product incorrectly. Fill deeper cracks with sand. Don’t just pour Epoxy Patch into a vast canyon of a crack. But if you’re at all concerned that the crack is structural, get a professional to assess the damage. Don’t expect a crack filler to fix a flood under the concrete structure. This product fills cracks with a hard, expanding, waterproof patch.  Learn how to diagnose a structural crack here. For up to 1 inch wide x 2 in. deep cracks, fix it with the easy to use Epoxy Repair that you can buy here.

tenacious grip, this stuff ROCKS … I am confident in this stuff. It is very powerful. My only issue, which is not the products fault, is that you do not have a long pot life on this… — Amazon reviewer

Sand is included with the product. The more sand you use, the tougher it will be to trowel. The product will work fine if you hold back up to a third of the sand.

Unlike other epoxies on this page, TurboKrete is not readily mixable by hand. Use a drill-powered mortar mixer. Apply TurboKrete only between 45 and 90 deg. F. It will dry to a light grey.

This stuff is perfect. I tried different things and I’m a contractor June 22, 2017 Verified Purchase

This stuff is perfect. I tried different things and I’m a contractor. Nothing is as easy to use and works well. I did use a 4″ angle grinder to open up the cracks, acid washed them out, blew them out, dried them and used this in two coats. It turned 100 linear feet of garage cracks to nearly perfection before I epoxied the garage. Highly recommend. Nothing is a miracle super quick fix, but this is pretty close. — Amazon reviewer

Best Self-Mixing Epoxy Crack Repair for Hairline Cracks

RTG Concrete Crack Filler

RTG Concrete Crack Filler

RTG Concrete Crack Filler is an epoxy, but you don’t have to mix it on cardboard or rush to apply it before it gets hard. That’s because RTG mixes the resin and hardener for you, right inside the dispensing tube. As you push the bottom of the applicator, two cartridges release their epoxy components into the tube. You get a mixed epoxy crack filler right out of the mixing tip.

RTG gives you a waterproof crack repair up to 1/2 in. wide. Install the applicator into a caulking gun, aim and fire. It’s best if you wait for warmer weather to apply RTG. Wait until it’s at least 55 deg. F. Paint after one day. Use a UV protective paint if the crack repair is in direct sunlight.

Great Products. Worked as Expected.

After being irritated for years by a long thin hairline crack in my workshop floor, I decided to do something about because I eventually plan on painting over it with an epoxy floor paint. This product had a fairly thin consistency that made it easy to fill the crack without making a mess or wasting too much product. The crack is completely filled now, and you won’t even know it’s there once it get painted over. — Amazon reviewer

  • RTG fills hairline and small concrete cracks
  • It’s really easy to use because the epoxy mixes in the nozzle as you dispense it
  • The crack seal is waterproof
  • It repairs cracks, holes and seams
  • Use it on concrete and cement steps, patios and garage floors
  • Use at least an 8:1 ratio caulking gun: 1 pound of force produces 8 pounds of pressure
  • Apply at temperatures of 55 deg. F. or greater
  • Wait 4 hours to sand
  • If repair is in full-sun all day, cover it with a UV protected paint
