Dealing with Surface Pitting During Polishing

Surface pitting is a common issue faced by many contractors when polishing concrete or terrazzo floors. These small holes or voids can be caused by air bubbles, improper mixing, or wear over time. If not properly addressed, these pits remain visible after polishing, detracting from the floor’s appearance and compromising its long-term durability.

Understanding the Effects of Pitting  

Pitting creates an uneven surface that disrupts the reflection and clarity of polished floors. Besides affecting aesthetics, these flaws can trap dirt and moisture, making cleaning and maintenance more challenging. It is crucial to address pitting during the polishing process to achieve a smooth, high-quality finish.

Methods to Manage Pitting  

The first step is to assess the extent of the pitting. Shallow pits can often be smoothed out during initial grinding, whereas deeper voids usually need to be filled with repair materials before continuing with polishing. After filling, polishing should proceed using the appropriate grit progression to restore a uniform texture and shine.

Importance of Tool Selection  

Choosing the right polishing tools is key to effectively managing surface pitting. After pits are repaired or leveled, resin pads for terrazzo can refine the surface and blend the repaired areas seamlessly. For concrete, concrete floor polishing pads serve as finishing tools to smooth out minor imperfections, while dry polishing pads are especially useful in environments where water cannot be used, helping complete the polishing process without causing moisture-related issues.
