Concrete Floor Preparation and Self-Leveling Compound

A common myth in apartment renovation is that self-leveling compound magically fixes any bad floor by itself. In reality, pouring expensive leveling compound over a dusty, unprimed, or weak substrate guarantees that the new layer will crack, delaminate, and eventually ruin the luxury vinyl tiles (LVT) or parquet installed above it. Correct floor preparation requires mechanical grinding of weak layers, thorough vacuuming, correct priming to manage absorption, exact water-to-powder mixing ratios, and the use of a spiked roller to release trapped air. Checking these steps ensures your new floors remain stable and quiet for decades.
