Concrete Polishing

Polished concrete is a process of progressive mechanical grinding, honing, densifying and polishing a concrete surface. This is done to achieve an aesthetically pleasing, highly durable, light-reflective finish.

Mohs Testing Will Save Time, Money and Frustration

In an earlier concrete polishing tip, I mentioned there are many options when choosing diamond tooling configurations and grit levels. Now we’re going to learn about another variable to consider. Today, we’ll learn how to match a diamond tool’s metal bond to the concrete prior to choosing the grit level […]

Was enough densifier/hardener applied to the polished concrete slab?

Densifiers/hardeners are either alkali metal silicates or colloidal silica. When your densifier of choice is applied to concrete and absorbed into the polished concrete slab, the silicate reacts with the free lime (excess calcium hydroxide) and forms calcium silicate hydrate (CSH gel). This reaction mimics the hydration of portland cement, […]

How to Create and Process
a Scratch-free Polished Concrete Floor

The first step to creating and processing a scratch-free polished concrete floor is to start by cleaning the floor you’re about to grind, hone and polish. Make sure the grinder is clean. This includes the bottom of the machine, the skirt and the diamonds. Inspect the surfaces of the diamonds […]

Polished Concrete Challenges
can be Overcome with Overlays

The aesthetics of polished concrete is often one of the primary reasons why it’s chosen as the finished flooring on many projects. The material’s natural beauty that’s expressed through varying aggregate reveals, the color of the cement binder and the clarity of the polished surface makes it a singularly unique […]

Which diamond tool should I use to start my project?

Choose the starting diamond grit and tooling segment configuration based on what’s best to achieve the job’s appearance objective. If there wasn’t one given, go with the random aggregate configuration. Objective # 1 Random aggregate (doesn’t matter what the reveal is) — objective is cutting through the cap Diamond Grit […]
