If you are painting and have accidentally gotten paint all over your concrete, you might think that there is no way to get the paint off, but really there is. If you have had this accident happen, there are some easy things you can do that will help get rid of the paint that accidentally went onto your concrete. As most people know, standard hand-scrubbing does not work and you might feel like giving up, but there is an alternate method to hand-scrubbing that works.
If you have paint stuck on your concrete you might want to think about pressure washing the area. The high water pressure that comes from pressure washing is the most common method for getting paint off of concrete, this electric pressure washing method is done for concrete that is outside and also this method does not work well on stronger paints like epoxy. You can buy an electric pressure washer at any local hardware or home improvement store, or possibly rent one for a day at a renting center or local home improvement store.
If you have a big job to do you might just want to buy one as they are only a couple hundred dollars, compared to renting one if you do not know how long the job will take you. Also, if you are trying to get paint off of a concrete surface that is outside you can try using a floor grinder with a diamond wheel, this method will leave scrapes behind and should only be used if you are going to go over the concrete with something else. If you do not mind having scrapes on your concrete from the grinder, then you can try this method, it is very effective and might be a better choice if you do not have the money to rent or buy a high-powered pressure washer.
Another very common method of getting rid of the paint on your concrete consists of you buying chemical stripping agents. Soy-based stripping agents are the best to use because they are the safest due to them being not toxic and the soy-based stripping agents are also some of the easiest agents to use to help remove the paint. The stripping agents come in a gel, and you can use the gel on the same area over and over, which you will probably have to because you have to repeat this process a number of times to get all the paint off of the concrete.
The stripping agents are good to use because you can get them at any home improvement store, and are fairly reasonable in price, but again, you will be doing this longer than if you were to use a best electric pressure washer. You just apply the gel to the concrete area where the paint is at and let it sit for a while, which helps the paint loosen from the concrete. Once it has sat for a while and the paint is loosened from the concrete you then use a thick plastic scraper to take off the paint from the concrete. This process might need to be repeated several times to ensure you have gotten the most paint off of the concrete as you can.
After you are satisfied with how it looks, take a nylon brush and rub the paint out as much as possible, which should only be particles of paint at this point. Make sure to add scouring powder and water to the affected area of concrete to help you brush the rest of the paint away. To make sure you have the concrete back to normal after the paint accident, you just rinse off the area with water and it should look as good as new. If you cannot get the soy-based stripper, and end up getting a toxic chemical agent you need to be sure to follow all safety guidelines that are associated with the chemical. Toxic chemicals can harm the environment and also can cause harm to your eyes, your hands and possibly your pet.
A shot blaster, which is similar to a sandblaster is another option if you are trying to get paint off of concrete. The shot blaster uses little metal beads to help get rid of paint on concrete, instead of sand like the sandblaster uses. This machine works well with getting paint off of concrete, and usually does not harm the finish of the concrete, although it will look better if you paint over it or treat the concrete after you use it. The shot blaster can chip your concrete if you use the machine too fast, so you need to go at a slow and steady pace with the machine. The shot blaster can be found at home improvement stores as well as in your local hardware store and will cost you under a hundred dollars typically.
