Is It Still Usable? How to Determine if Your Self-Levelling Compound Is Still Good
Yes, you can still use it if it’s been opened and shows no signs of spoilage! The primary concern with self-levelling compound is moisture infiltration. Moisture can compromise the quality of the mixture, rendering it unusable. To assess its condition, simply open the bag and inspect the contents. If the powder remains dry and free-flowing, it’s safe to use. However, if you notice any clumps or hardened sections, it indicates moisture has entered, and the compound may not mix properly, leading to uneven flooring. In such cases, it’s advisable to discard the hardened material. Over time, if self-levelling compound is stored improperly or left exposed to humidity, it can eventually become a solid block within the bag, making it unusable.
What Is Self-Levelling Compound?
Self-levelling compound, also known as floor screed or leveling mix, is a cement-based material designed to create a smooth, flat surface on uneven subfloors. It is typically applied in thin layers over substrates like concrete slabs or wooden floors before installing final flooring materials such as tiles, vinyl, or hardwood. The key feature of this compound is its ability to self-level—meaning it flows across the surface, filling in bumps and dips, to produce a level base. Although it is called ‘self-levelling,’ it has practical limits. It won’t flow perfectly over large distances like water, so some manual assistance might be necessary to achieve an optimal finish, especially over extensive areas.
Reasons to Use Self-Levelling Compound
Applying self-levelling compound is essential when preparing a subfloor for rigid flooring types. It transforms an uneven, bumpy surface into a perfectly smooth and stable foundation. This is crucial because a level base prevents issues such as cracking or movement in tiles or wooden flooring. Without proper leveling, tiles may crack or loosen, and wooden floors may develop bounces or creaks. Conversely, softer flooring options like carpets or vinyl can comfortably accommodate minor imperfections, but for solid, durable finishes, a level surface is vital to ensure longevity and aesthetic appeal.
