How to Repair a Concrete Slab Floor How to Repair a Concrete Slab Floor
It is a smart thing to learn how to repair a concrete slab floor. This type of material is used in many different homes and it is likely that you will live in one that needs repairing at some point in your life. Concrete slab floors are great because they are reasonably priced and versatile, however there are the occasional problems that need fixing. Here are a few tools and materials that you may need, along with some quick steps that can help to guide you if your concrete slab floor needs repairing.
Step 1 - Prepare the Area
Before doing anything to repair the hole or crack, you will want to clean the area off. Use a screwdriver to pry off the ends of any chunks that are coming undone and a vacuum or broom to get off any debris. One key trick to repairing concrete slab flooring is the get the area you are fixing wet. This should be done a few hours before you do the job and will help the area to be moist enough to adhere to the cement. Use a sponge and water to squeeze and dampen the area.
Step 2 - Mix Cement and Apply
In a bucket, follow the directions on the cement and mix it to a paste-like consistency. You want it to be thick, but not too thick that you can't work with it. Using a putty knife, you can slowly apply the cement that you mixed to the crack or hole in the cement slab that needs to be repaired. While you are working, make sure that you are cleaning up any excess cement that gets on the floor so that it doesn't dry and become uneven. Continue to watch the area that you just worked on for about 24 to 36 hours. You will want to keep spraying a light flow of water on it to make sure that the cement sticks in the cracks and holes like it should. Spraying water in can be tricky if you have never done this kind of work before. You want to make sure that you do not put so much that it is watery, but do not let it dry out either. This step is similar to watering a plant.
Step 3 - Seal
Allow the area to dry after the first 24 to 36 hours. Typically this will take a few days to adhere and then dry properly. After about 3 to 4 days, you will want to apply a sealant to the floor. It is best to apply it to the entire floor to keep it protected and also so that the look isn't uneven. Begin in one corner of the room and move your way to the door. Paint the floor with the sealant and a roller or brush, depending on the size of the room. Allow the sealant to dry for about 24 to 48 hours before walking on it.
