Concrete Epoxy Patch, Repairing Cinder Block Wall Cracks or Holes

Finding a crack or even a hole in a cinder block wall or even concrete can be daunting for the average homeowner, don't panic yet as it can be repaired!

It is best not to attempt basement walls until the reason for the cracks is determined by a professional and repaired as it could be a much bigger problem than just "a crack"

In Florida, cinder block homes are nothing new. While remodeling the "office" as I call it (I'll not mention what my wife calls it,) installing ceramic tile flooring, removing very old wallpaper and painting I received the usual surprise when from under the paper covered walls sprang... cracks.

There were even a couple of areas where the original builder had built the wall up to hide defects when finishing the wall. After 30 years the drywall compound had dried and begun to flake, leaving me ample room to practice my skill at patching.

There are several products available suited to our project, but an epoxy concrete patching mix is best for what we want it to do. It needs to be able to have a thin layer in places and still adhere well epoxy patch will do that. Always read the instructions, as some products can't be spread thinly or shouldn't be.

If the crack is very thin it may be necessary to widen it with a four-inch disc grinder be sure to wear eye protection, as it will throw concrete dust at you. A dust mask is another necessity as breathing the concrete dust is definitely a bad thing! All that's needed is a small v groove on the wall so don't get too carried away.

At this point you really need a good shop vac, it can suck up all the dust and smaller debris without destroying itself. The area needing patched must be clean; I used a wet rag to eliminate any residual dust as a final precaution.

Before mixing any material be sure to have a few items on hand as once you start you can't leave it for very long or it becomes...concrete.

1) You need a small trowel to spread and mix the epoxy concrete patch with
.
2) A 10 to 12 inch long flat trowel with the handle in the middle of the back portion makes it easier to spread over larger areas or feather the edges.

3) A five gallon bucket to mix and carry it in
