Concrete Floor Repair

Concrete floor repair is a simple project which many homeowners can easily do by themselves in just a few hours. Although concrete floor repair is such as simple project it is one that is very important. Failure to repair concrete floors in early stages when the cracks are relatively small can lead to problems which grow progressively worse. This article will discuss the products and tools needed to repair minor cracks in a concrete floor and will provide step by step instructions for repairing the cracks.

Tools of the Trade

Concrete floor repair is not a very involved project and the tools and products needed to fill cracks in concrete are very small in number. A hammer, chisel and a trowel are needed as well as safety goggles.

Additionally, some form of cleaner is needed. If the cracked area has grease in the vicinity, it is wise to use a cleaner with grease removing capabilities. It is important to properly clean the area because grease and other debris may impede the ability of the filler to adhere.

Finally, some type of crack filler is necessary for the concrete floor repair. The size and cause of the crack will determine which type of filler is most appropriate. For most small cracks a latex, vinyl or epoxy patch will be suitable for use in the repair of the cracks. These patches come in a tube and are easy to apply. However, if the cracks are caused by water damage, the use of hydraulic cement will be necessary. Hydraulic cement is commercially available in a powder form and must be mixed with water.

The Step by Step Process

As previously mentioned, concrete floor repair is not a difficult process. Most homeowners find the process to be simple and also worthwhile because it can prevent minor cracks from turning into more serious problems. Listed below are step by step instructions for repairing minor cracks in concrete floors:

    1. The first step in the process of concrete floor repair is actually to make the crack bigger. Use a hammer and a chisel to widen the interior of the crack. This part of the process is known as keying and is necessary because it makes it easier for the patch to adhere. Be sure to wear safety goggles while chiseling to avoid being hit in the eye by flying debris.

    2. After keying the crack, thoroughly clean out any dirt and debris. Vacuuming is a good method for this process. However, cleaning with a degreaser might be necessary if there is grease in the crack.

    3. Next take the concrete filler and place it into the crack. If using latex, vinyl or epoxy patch kits this step simply involves squirting the product into the crack. For hydraulic cements, it might be necessary to use a trowel to smooth the filler in place.

    4. Allow the filler to settle for a few minutes and then check on it to see how much it has settled. It might be necessary to add more filler at this point.

    5. Next use a trowel to smooth the filler to create a level finish.

    6. The filler should then be allowed to cure overnight and rechecked after 24 hours to see if there was any further settling. If so adding more filler and repeating steps five and six will be necessary.

    7. Once the crack is completely filled, sealing the floor is recommended.
