Floor Grinding : Understanding the Process and Importance of Concrete Floor Grinding

 Floor Grinding is a process that transforms old concrete into a smooth and shiny surface. It removes blemishes and imperfections from the concrete, which increases its longevity and makes it a more usable surface. This is especially useful for commercial and residential spaces that are in high traffic areas.

A floor grinder works by moving the machine over the surface of the concrete and rotating discs underneath, which contain abrasive pads that grind or polish the surface. The number of discs and the grit size varies, depending on the type of machine and the material it is working on.

 Typical floor grinder

In a typical Floor Grinding , an operator sits on or walks behind the machine and moves it in smooth, even movements. The abrasive pad or pads are typically encrusted with industrial diamonds, which are available in different sizes and strengths.

If you're not familiar with the process, it's important to understand that the abrasive can create a lot of dust and need to be sucked up by a vacuum. This can be a hassle, so it's best to choose a contractor that is experienced in keeping the messes to a minimum.

Concrete floor

The concrete floor can be ground using a dry or wet method, and there are certain tools that can help reduce the amount of debris generated during this process. Generally, contractors use resin-bonded abrasives for dry grinding and metal-bonded diamonds for wet grinding.

With a wet grind, the abrasive is saturated with water to reduce the amount of dirt that is produced during the grinding process. This allows the contractor to keep the messes to a minimum and make more efficient use of their time.

This can also be a great way to prepare a concrete surface for sealing or polishing. The floor can be polished prior to being sealed, which improves the appearance of the surface and prevents the need for additional coats of sealant.

 The grinding and polishing process

When you choose a contractor, ask about the grinding and polishing process and whether the concrete will be wet or dry. If the process is wet, the contractor may use special dust-containment systems that prevent the accumulation of grits and debris on the concrete.

 The machine and causing gouges

For a smoother and cleaner finish, it is recommended to sweep the concrete before each pass. This will help to minimize the likelihood of debris getting stuck in the abrasive or the machine and causing gouges.

It is also essential to follow a pre-determined sequence when grinding wood floors, as this will ensure that the floor is left with a consistent scratch pattern across the entire length of the floor. The abrasive should progress from a coarse to fine grit, but not skip any steps along the way.

Conclusion

Another thing to consider is how much the floor will be moved during the process. When the floor is moved, the machine's abrasive is more likely to get caught in the moving pieces and cause a mess. To avoid this, keep the cutter head moving as you grind.
