However, it’s important to note that the type of sander you should use will depend on the state of your concrete. For instance, if your concrete is still relatively smooth with only a few rough spots, you can use a handheld orbital sander with diamond abrasive discs.
On the other hand, if your concrete is severely uneven or has many deep stains to remove, you’ll need to use a larger floor sander with heavier grit sandpaper. Remember to wear proper protective gear, such as a mask and earplugs, and make sure to thoroughly clean up the fine dust created by sanding. With the right tools and precautions, using a floor sander on concrete can help you achieve a smooth and polished surface.
Types of Floor Sanders
Using a floor sander on concrete can be a great way to revitalize your old garage or basement floors. For this task, you will need to use a specialized type of floor sander known as a concrete sander. Concrete sanders typically use diamond-tipped abrasive pads to grind down rough and uneven concrete surfaces to a smooth finish.
This type of sander is perfect for smoothing out rough spots caused by settling or surface damage like tire marks or oil stains. Keep in mind that using a floor sander on concrete can be a messy job, so be sure to wear protective gear and cover any surfaces you don’t want to get dusty. With some patience, you can achieve a beautiful and durable finished surface for your concrete floors that will last for years.
The Right Abrasives and Grits to Use
Using a floor sander on concrete can be a challenging and time-consuming task but with the right abrasives and grits, the process can be much smoother. Diamond abrasives are the best option for grinding and polishing concrete surfaces. They come in different grades, ranging from coarse to fine, depending on the level of abrasion needed.
Coarse diamond abrasives work best for removing old coatings or leveling uneven concrete surfaces, while fine diamond abrasives are perfect for polishing and achieving a smooth finish. Choosing the right grit is also crucial in achieving the desired finish. The lower the grit number, the coarser the abrasive.
For example, a grit of 30 is considered coarse and is ideal for removing thick layers of concrete, while a grit of 400 is considered fine and is perfect for achieving a matte or satin finish. It’s important to note that using the wrong abrasive or grit can damage the concrete surface and result in an uneven finish. Therefore, taking the time to choose the correct abrasive and grit is key to achieving a professional-looking concrete surface.
Preparation of the Concrete Surface
If you want to prepare a concrete surface for coating or polishing, using a floor sander should be your go-to option.
