How to level a concrete floor by DIY method
Steps to level a concrete floor
- First, sweep or vacuum the floor clean. Then scrub it with sugar soap, diluted according to the manufacturer’s instructions. Rinse it off with plenty of water and leave it to dry for a couple of days. If the room is cold, put in temporary heating to ensure the floor dries completely.
- Dents are best filled with a small amount of the self-leveling compound, which must be allowed to dry for 12 hours before you lay the all-over coat of compound.
- Follow the manufacturer’s directions for mixing the compound with cold water. A trowel is a good tool for mixing. Because the compound will start to dry after 10 minutes, at first mix only about an average-sized bucket for each batch. As you start to work more quickly, you can make large batches.
- Just prior to using the compound, dampen the floor with water. This prevents the compound from drying out too quickly and possibly cracking at a later date.
- Pour the mixture onto the floor, a bucket at a time. It will start to spread out in a puddle, so allow space for it to spread to any neighboring walls.
- You can assist the compound in spreading by using a steel float. Hold the float parallel to the floor and move it in a semicircular motion. You should notice the float marks disappearing as the compound dries.
- Should you not-at first – be able to use the float with complete success, then immediately sprinkle water onto the compound to prevent it from drying and try again.
