The question can you paint a concrete floor keeps coming up because like you, most people are tired of the look of the old concrete floor. And you want a new look to lighten up your house in a unique way. Well, the answer is a big yes.
A specific paint made for concrete floors is used in painting it although any paint can do the job, but it will fade with time. It can be painted in any color of your choice, and you can decide to design it too. In a house where the carpet does not look good anymore, you can choose to rip it off and paint the floor alone.
Painting your concrete mandates more skills, time, and tools. It is nothing like painting a wall. When painting the concrete, it breathes, spreads moisture, and sucks up paints. It requires more paints and coating that would go on for days to a week. After the painting has been done, you can use a concrete floor sealer to finish it all up.
Types of Concrete Floors
There are two main types of concrete floors that are mostly used by people. It is essential to have an idea of the type of concrete floor you own. This is to enable you to know what it is compatible with.
Power Floated: This is the most widely used concrete floor. It is polished with a machine before it is cured. The surface is left with a smooth and sleek hard-wearing look. Before a paint or stain is applied to it, the surface must be sanded or chiseled.
Screeded: This standard concrete floor is applied on a poured concrete slab. They have rough unpolished texture because they went through the process of hand finishing with a wooden float. It has porosity features that a power floated floor does not possess.
How do you Prepare a Concrete Floor for Painting
Some steps are required to carry out the concrete painting process. These steps should be followed sequentially to avoid mistakes. With these steps, you can get your floor ready for your paint to have its way.
Removing the Carpet
Most times the concrete is not bare on its own, it might be covered with carpets, tiles, or vinyl. Before the painting goes on, the carpet needs to be scrapped off. When the rug is out, tack strips should be removed as well. They are those pieces of wood along the edge of your carpet that holds it in place. When that is done, remove the carpet glue using a hydrochloric acid solution which must be diluted with four parts water.
Wear a glove, mask, and protective eyewear, and make sure to work in a well-ventilated room.
Cleaning the Surface of the Concrete Floor
This step is the most crucial point because specks of dirt, holes, oil are on the floor surface, and paints will not bond well. Before painting takes place, there should be a clean, smooth floor to make the whole process blend. Use a degreasing oil to get specks of dirt out.
When the specks of dirt feel hard, use a stiff brush and a trisodium phosphate mixture to remove the traces of dirt. When the surface is dry and clean, then the holes and cracks should be repaired. It can be done with a concrete patch kit, and all the holes must be repaired before proceeding to the next stage. Paints stick well to a textured surface.
You can test if you have achieved a smooth surface by pouring water on the floor. If it soaks, then it is ready to be painted, if not then keep roughing up the body. You can also test the moisture on it by pasting a square of plastic or aluminum wrap to the floor and wait for when the condensation is not present. Fill the holes with a concrete patch if any.
Strip the Old Paint If Any
The old paint both indoor and outdoor should be stripped off using a paint scraper or wire brush. In most cases, carpets cover up the concrete, and this same tool can be used to scrape it off. You may want to sand your floor, and doing this requires more energy. You will keep sanding till it is very smooth. After sanding, you will need to sweep or vacuum it consistently till they are out.
The floor should undergo this process because it gives it a smooth finish. It helps guarantee that your paint will stick. Select a primer that is suitable for your floor and paint. Using a paintbrush, apply the primer at the edge of the room before applying it to the floor using a paint roller.
Make sure you keep a wet edge by not allowing the paint roller to dry out. It helps impede visible roller marks on the floor.
The paint should be specifically designed for a concrete floor. While painting, you should start from the proper angle of the room and work towards the door. You can choose to use an acid stain instead of paint. The procedures are the same as using paint. Follow the instructions on the paint or stain label, mix well, and apply to get the best results. You should coat the floor up to two to three times and allow each coating to dry before applying another.
Seal the Work
After painting, please read the instructions on how long it will take to dry before applying a sealant for durability. Choose one that is made for your exterior or interior floor and also compatible with your paint. The temperature written down by the manufacturer should be adopted to avoid the paint from peeling off in a short time.
Brush the sealant at the edges and the floor and allow it to dry. Then wait for a fantastic look that will last for years.
