Ardex NA vs F. Ball Stopgap: Which Levelling Compound Is Right for Your Project?
A smooth, level subfloor is essential for achieving a professional flooring installation. Whether you're laying LVT, vinyl or carpet, choosing the right levelling compound can make all the difference.
Both Ardex and F. Ball Stopgap are well-known names in the flooring industry, offering high-quality smoothing compounds for a variety of subfloors. However, Ardex has become a popular choice for installers looking for reliable performance and a complete flooring system.
Performance Compared
Both Arditex NA and Stopgap 1200 Pro are premium two-part latex levelling compounds, making them ideal for refurbishment projects where speed and reliability are essential. Both can receive most floorcoverings in around 4 hours, are moisture tolerant, and can often be applied without priming on suitable substrates.
One notable difference is application depth. Arditex NA can be applied from 2–20mm in a single application, whereas Stopgap 1200 Pro is designed for 2–10mm, requiring the addition of aggregate for thicker applications. This gives Arditex NA greater flexibility when dealing with uneven subfloors.
Arditex NA also becomes walkable in around 2 hours, helping installers progress more quickly on busy projects.
