Nowadays, homeowners prefer installing or adding the concrete floor because of its easy maintenance. Not only for this, but the concrete floor also looks more attractive and appealing than other floors. However, owners and floor builders have to sand the floor for revelation and appearance.

If you are also looking for the answers to these types of questions, you are at the right place. We have collected the best steps and techniques from sanding the concrete floor effortlessly.

A Few Considerations For Sanding The Concrete Floor

Most of the people are focusing on the floor sanding to give it a wholly exposed look. These floors are super easy to clean and maintain. But you have to install or sand the floor appropriately before thinking about keeping it. If you want to rub the concrete surface, make sure that the surface is smooth and level.

Undoubtedly, figuring out how to sand the concrete floor is a more difficult question than maintaining the floor. Don’t worry; it’s not something that you cannot do yourself. One can surely sand the floor himself by following a few expert-level instructions and guidelines. So, let’s take a deep dive into all the steps for better considerations.

Clean And Smooth The Surface

Even before thinking about sanding the floor, you have to clean the surface appropriately. It’s completely useless and a waste of money to sand the dirty and uneven floor. Therefore, it’s better to find out all the irregularities while cleaning. Moreover, inspect or examine the complete floor for cracks and any damage. So, you can fix the damages earlier.

Keep in mind to remove the concrete bumps from the corners more carefully. Don’t use the sharpest tools for this purpose. You can use the chisel or a simple scraper to remove all the bumps without floor damage safely.

Choose The Sanding Tools Wisely

Determine the type and condition of the concrete floor before choosing the sanding tools for it. If you have to sand the floor entirely for total exposure, use an orbital sander.

It’s up to you to use the orbital sander wet or dry according to the floor’s condition. Unfortunately, you cannot get the desired results with this tool, and it will also take more time than usual.

However, you can also go for a grinder if you have already done some sanding projects. Otherwise, it will be difficult for you to use this sanding tool.

Well, there are many types of sanders available in the markets. But you still have to choose one according to your skill level and floor’s requirements.

Determine The Range Of Sandpaper’s Grits

As we mentioned earlier, the selection of sandpaper depends on the floor’s conditions and your skill levels. Similarly, you have to choose the grits of sandpaper accordingly to get your job done nicely. If you are searching for the basic level sanding, go for the lower grit sandpaper. However, use higher grit sandpaper for the smooth and proper floor finishing.

If the floor is not in good condition or crack from different points, use the grinder instead of sandpaper. Are you working for the first time on the floor sanding? If yes, choose the basic grinding disc instead of a higher one.

Start From Corner To Ends

Well, it’s great to hire professionals for the sanding. But if you don’t have enough budget and time, you can do it yourself. For this, you have to work in a professional pattern or method to achieve successful concrete floor sanding results.

You can start sanding the area from corners to end to complete it smoothly. Moreover, you can also work in the small sections to get the job done effortlessly. In this way, you can cover the complete area even without leaving a single corner.

Ideally, you can also use the grinder even after using the sandpaper to achieve smoother and grandeur results. Once you have sanded the floor, please wait until it dries completely.

Clean the floor thoroughly after drying. In this way, you can remove all the sanding dust, dirt and debris. Remember, it’s always better to remove the bumps and sand debris earlier after sanding. Over time it would be difficult for the owner to clean the floor.

Use A Concrete Sealant

Do you want to give a glossy finishing to the floor after sanding? If yes, use a concrete sealant after the sanding process. Not only for the attractive appearance, but sealant is also essential to save and maintain the floor.

Even after post-sanding cleaning and sealing, you have to clean the floor from time to time to keep it durable for a long time. Moreover, you can also apply the sealant after the yearly cleaning of the base yourself for a better concrete surface.

Maintenance Is Essential Even After Sanding

Once you have sanded the concrete floor, it’s time to maintain it appropriately. Not only after sanding, but you have to clean and maintain the base over time for the betterment and appealing look. For this, you have to wet mop the floor daily with a damp or soft cloth. Use natural cleaners and ingredients instead of using chemicals and detergents.

If you have kids or pets in your home, spills and spots on the floor will occur. It’s better to clean the wet and fresh spills than to dry them. Otherwise, it would help if you put more time and effort into cleaning the dried spots.


In short, sanding concrete floors look better than any other type of floor. However, it would be most efficient if you do the sanding with the help of professionals.

But it’s worth it to sand the floor yourself by following the steps discussed above. Hopefully, you have enough information from this article to get a compelling and splendid concrete-sanded base yourself. Now, it’s your turn to get help from this post and sand the concrete floor.
