Prepare the flooring

Once a concrete floor is covered using a fresh color, its condition remains noticeable. Imperfections like swellings or cracks that are not dealt with before applying the painting will not change even in texture. This means the difference will attract many people’s attention. For that reason before beginning the process, you must ensure that the surface becomes very clean and extremely smooth.

Scrap off all the gunk

Flooring is usually notorious to have stuck-on paints from splashes and epoxy residue. Luckily, getting this away is no longer an energy-consuming task. Thanks to the available scrapers, you can fix it quickly to a pole, and voila. This strong tool has a firm, blade made from steel that makes scraping away the toughened residue simple. Just thread the pole to the handle, you will realize that its blade is angled and bent properly for comfortable work while standing.

Keeping in mind that new paint will stick well on a clean and dry surface, work carefully. For excellent results and less peeling by the end of the day, degrease all the interior concrete flooring. Because the cleaning products are usually applied when the surface is damp, put on the protective gear on the eyes, body, and hands. Then spray the floor carefully.

The effectiveness comes because the interior floors will not dry out quickly compared to the ones outside. Apply the degreasing product as per the guidelines on its label. Using a hard push broom scrub this solution to the floor and direct the solution out. If there are any stubborn spots, use the right masonry rust removers. And scrub the stained area using the wire brush.

Need Appropriate Brush

Ensure that the brush used is easy to hold on your hands. The handle should be soft, and ergonomically designed for grip or straightforward attachment to the pole. That way you do not bend down and strain your knees and hands while scrubbing larger stained areas. The bristles should be hard enough to retain the original shape even after use in removing stains on the whole floor.

If you find that trickier, you can clean the floors using a pump sprayer. This will drench concrete thoroughly with water, after which the degreaser should be applied following the manufacturer’s instructions. Then scrub well using the push broom. At that time bring a vacuum cleaner for removing any excess liquid. The spraying process can be repeated, and the water vacuumed up every time, to rinse the degreaser agent away completely.

Check out any existing cracks on the floor. Why? This is a potential cause of damage to the new finish. Use a concrete filler it adheres well especially to clean cracks. So ensure you remove any peeling concrete with the wire brush. Without doubts, its narrow tip will enable the bristles to go deep into the cracks and corners. Additionally, the ergonomic soft-hold handle will minimize fatigue on your hands as you easily grasp it. Any debris can be cleared using the vacuum cleaner and then the cleaned cracks filled using the crack filler. The caulking gun will typically dispense it precisely. Then use the putty knife to smoothen the excess. Once it dries up, use the sandpaper to lightly sand the cracks.

Prime and then Paint

how to paint interior concrete floors

Before painting concrete flooring, it is vital to prime. This ensures that the freshly anticipated looks will stick for a longer time. So choose a primer that blends well with concrete and the paint that will be used for finishing the surfaces. The best choice is epoxy because it handles well high foot traffic. With this durable results is granted, and also an excellent hold over time. The select paint and primer must be fit for use on the interior floor.

Before priming, wait for the floors to completely dry. Remember that wetness prevents paints and primer from sticking well. One quick way to determine if your floor is already properly dry is to put a piece of a plastic wrapper on its surface. The wrap should be sealed on the edges using tape. This can go overnight before checking the covered plastic. If this plastic shows signs of moisture from underneath, then you should allow the flow to dry for an additional 24 hours. When the time elapses test it again. If you see no condensation then you can continue with the process.

Large renovation projects often require different applicators. So check through to ensure that all that you need is available. Stopping while in the middle of a task to get a tool or an item is risky. The paint may dry out prematurely and leave visible marks from the roller or brush. Before starting out ensure no essential piece is forgotten. Well, you can buy complete kits to save on the supplies. For instance, there are paint and roller kits that include all the essentials for prime and paint rolling. If you get a threaded frame equipped with a standard pole then you will roll comfortably while standing.

Before Applying the Primer

Before applying the primer, cover the undersides of all columns, posts, and baseboards using the painter’s tape. With the paintbrush spread over the primer everywhere on the concrete flooring posts and also on all the floor edges. When you have attained a clear cut all around the ends, apply all the primers using the paint roller. Keep in mind to begin rolling from the opposite side of the door to avoid closing yourself with paint in a corner.  Always work in thin swaths, approximately 2 feet in width. While still continuing with the work, never allow the already applied swath to dry out completely before rolling another one. This way your finished floor will not have noticeable roller marks.

Check to see if the applied primer coat is completely dry then add epoxy. Epoxy paint is sold in two parts, so both must be mixed together following the guidelines on its label before you begin painting your floor. Use the same procedure you followed while applying the primers.

Seal the Flooring

Check from the epoxy covering label for the time you wait for it to completely dry. when the time comes, be sure that the floor will have fresher and amazing looks. For you to get long-lasting results, applying a sealant is a wise idea. Always buy a sealant meant for interior use and also see into it that it will match well the epoxy that was applied.

Follow the maker’s guidelines for temperature, ventilation, and humidity. Failure to do this you will notice the product peeling off within one month or after one year. Remember even nicely done floors get in ruins if you do not pay attention to the needed cure temperatures.

Sealants are also applied with the same method used for applying the paint and primer before you step on the floor. This adds a glossy finish and also offers a durable protective coating. This also prevents any form of fading on the paint. So the flooring will still look good after some years.

How to Clean Up the Concrete Floor

The good thing is that the sealants, primers, and paints used today are easy to clean. Water and soap come in handy after the process. The paintbrushes and rollers should be soaked quickly to prevent the drying of paint on them. The tools can be reused for painting the flooring if washed thoroughly after use.

There is a designed roller cleaner that makes its maintenance simple. With its easy-hold handle and curved edge, it will push the paint from the roller. Equipped with tines it works like a comb to pull off the most sticky paint from the bristles.

The one-use pan liners should be tossed off while the plastic roller pans kept for coming uses.

If the sealant is completely dry, cut the tape’s edge with a blade before removing it. Cutting provides an easy pull-off and a neat edge. This also holds the tape’s edge straight when cutting.


Finally, in case your garage, basement, or patio flooring is concrete then it is time you should do away with dull. Yes, painting can completely refresh the looks of the space. Together with the right masonry tools and procedures, you can easily turn the floor into a nice-looking surface. This will be a great complement to different indoor spaces.
