Carrying out cement floor repair is required when you have cracks on your cement floor. Though it is not a complicated process, yet it requires skill and a proper understanding of how to do the job. With the right tools and the materials you can carry out the repairs on your cement floor by yourself instead of calling in a mason. You can also save a lot of money by doing the job yourself.
Check the Area that Needs to be Repaired
Check the damage in order to be able to find a solution or fix a problem. Cracks, ridges, bumps, humps, depressions and chipped surfaces are some of the common problems with cement floors. In case the damage is on a small area, it will take more precision and effort. Large repair areas are easier to work on.
Creating a Rough Surface
The first step in cement floor repair is to chip the surface of the affected concrete area. This will help the cement mixture to bond later on. For a small area of work, a chipping hammer will do the trick. If you are looking at a vast area you will need an electric chipping hammer or a jack hammer. Work around the area that is damaged and requires repairs. Chip the floor properly so that when you apply the fresh concrete it bonds well.
Mixing the Cement
Mix 1 part of cement to 2 1/2 parts of clean sand. Follow it up with a latex or liquid bonding agent. The quantity of the latex should be enough to bring the mixture to a stiff plastic consistency. Follow the instructions on the bonding agent before you use it. Certain brands have different methodologies. Remember to use gloves while working.
Preparing the Surface
The area where the mixture has to be applied needs to be rid of dust and debris. Follow it up by wetting the area with clean water. Wetting the ground will work as an adhesive and will prevent the mixture from drying up quickly. A dry surface will harden the mixture by absorbing the moisture which will later cause the cement to crack.
Applying the Mixture
Use a trowel to scoop out the mixture and spread it on the surface with pressure to eliminate any air bubbles. Level the surface of the mixture with the trowel. Let it be a few inches above the existing level, this will give tackle shrinkage. It generally takes an hour or so to become stiff.
When the cement becomes a bit stiff use a trowel to flatten and make the surface smooth, this will make the paste rise. The paste forms the surface of the finished slab. In another 2 hours the area will become hard. Splash some water to avoid moisture loss.
