Thin/ Light Concrete Repairs
Over time exposure to the elements surface concrete can become worn and develop scaling, small cracks, and other minor dents. Careful preparation, the correct water-to-cement ratio can help prevent these situations. However, it is important to know that durable repairs can be made to the affected area extending the life of the said concrete surface.
The first step in achieving an effective repair is surface preparation. A solid clean surface is necessary so the overlay or other concrete application can permanently bond to the damaged area. It is important to remove any chips, damaged, and loose concrete from the area. Once the surface has been cleared, the concrete surface should be cleaned with a stiff bristle or wire brush and pressure wash thereafter. There are other cleaning agents that can be used to effectively clean the surface

For small cracks and dents, there are a number of patching products that can be used in lieu of replacing the concrete. For bigger repairs, a new cement mix is best advised. Before application of patch or cement mix filler, make sure that the surface is dampened with water. Apply mix, smoothening out the surface firmly as the first layer. The bigger/wider the cracks, you will need to add more layers of concrete to achieve maximum results. Just like any other concrete application job, do not apply if the temperature is freezing cold or scalding hot.

For badly spalled concrete surfaces and many patches, it is best to prepare by grinding away as much of the residue as possible. Each job will tell you how much grinding, chipping, or hammering away you will need to do. For excess debris, the best practice is to keep an Air-vac handy to pick up all loose small particles left over by removal. Again, for concrete repair purposes, preparation is always the most important. Moistening and blowing away the area to feather out all debris is crucial.

The concrete mix/patch mix that you use needs to spread evenly and thinly. You will gauge the spread once you’re in the midst of applying the layer. The layers should be easy to trowel over the surface. Don’t mix the whole bag at one time either, give yourself ample time to not rush said project. Take your time and pay attention to all the small cracks and crevices. Let the trowel do the work as you continue spreading the mixture over the surface. It should take 30 minutes to an hour depending on weather conditions.
Once you’ve allowed the concrete to correctly dry, it is best to go over the surface area with a rubbing stone lightly, smoothen out any clumps, trowel marks, or anything that’s still rough. Once again, wet the concrete surface area before you apply the resurfacer. Blow away and let dry any excess moisture. Mix your resurfacer to specifications and again apply with a trowel, letting the tool do what it’s meant to do.
