Wet Vs. Dry Concrete Grinding & Polishing-What You Need to Know

2020-09-13

Concrete can be polished using both wet or dry techniques, and contractors generally use a combination of both methods. Wet grinding concrete involves using water, which makes the diamond abrasives cooler and eliminates the dust from grinding. By acting as a lubricant, water can also prolong the life of your abrasive tools—particularly the resin bonded discs, which may melt under high temperatures. The downside of wet grinding is that this technique can be messy. The slurry that is a by-product of this process must be disposed of by crews, which can add to downtime and prolong your project.

A concrete grinding contractor can use special dust-containment systems if the chosen grinding method is dry polishing. This water-free technique is typically used at the beginning of a project when the largest volume of concrete is removed. Crews may switch to wet grinding as the concrete becomes more smooth and metal-bonded diamonds are swapped out for resin-bonded abrasives. In some cases, contractors may use resin-bonded discs that are designed for dry polishing to enable the entire process to be free of added water.

Concrete grinding is a dirty job. With the help of an experienced concrete contractor, however, you can minimize the mess, increase your productivity with your new flooring and get back to using your space quickly.
