How To Get Spray Paint Off Concrete As Well As Other Kind of Paints

0

Concrete paint is good for covering concrete with a tough, water-repellent layer. It protects the substrate from the weather for a long time. Of course, it is not water-soluble and therefore cannot be washed off as easily as conventional wall paint. But what if the concrete stained by spray paint or any kind of paints? In this article, you will find tips on how to get spray paint off concrete as well as other kind of paints.

How To Remove Concrete Paint Effectively

Concrete paint is designed to increase the durability of concrete. For example, it prevents moisture from penetrating, which could crack the surface in the event of a subsequent frost.

Even this hard-wearing paint does not last indefinitely. After a few years it starts to peel off and you want to remove or repaint the paint. However, the paint can only be removed in a few places and is firmly bonded to the substrate in many places.

Chemical solvents are ineffective, concrete paint can only be removed mechanically. The simplest means suitable for this are a wire brush and a hammer. This way you can tap off the color bit by bit. This is very complex, but it works.

If you want to go faster, use an angle grinder. A normal grinding attachment would immediately stick together due to the heat generated. As an alternative, you should therefore use a grinding disc such as is normally used for metalworking.

In order to tile the floor, you do not necessarily have to remove the paint. Concrete paint as a substrate is very smooth, but can be made slip-proof with a primer and then sprinkled with quartz sand. Simply use flexible adhesive to glue the tiles. At the same time, it also fills small cracks.

You can also use a high-pressure cleaner to clean the concrete thoroughly. However, fine splinters of paint still have to be brushed off afterwards.

Accessories you need to remove spray paint from concrete

  • paint remover or paint thinner
  • scraper
  • pressure washer or high pressure washer
  • safety goggles
  • Bristle brush or scrubber
  • goof off
  • elbow fat

Remove Spray Paint from Concrete 

Now that you’ve gathered the right materials, here are the top 5 steps to removing spray paint from your concrete wall, garage floor, or any concrete panel that’s affected!

  1. Use a solution to saturate the area
  2. Go over the area with a spray bottle full of hot water
  3. Scrub with a stiff bristle or wire brush
  4. Reapply the solution until the color has completely faded
  5. Thoroughly rinse the concrete with hot, soapy water until clean

Step 1: Use a stain remover solution to soak the area

The first thing you need to do is saturate any color stains with your chosen color remover solution. We recommend Goof Off for most stains as it is a proven spray paint remover.

Well, before you soak the entire stain, try your remover on a small spot of concrete first to see how it reacts. If it’s too abrasive and wears away the concrete too quickly, you should look for another solution.

However, if it works well and you see some progress, soak the entire stain and leave for a few seconds.

Step 2: Go over the area with a hot water sprayer

Next, you should treat the area with a pressure washer, pump sprayer, or other form of pressure washer that you have access to.

Not only will this splatter away the paint that the solution has loosened up, but it will also dilute the paint thinning solution on your concrete and minimize any damage.

As you spray the stain, keep an eye on how much of the stain is being removed. Sometimes you can get it on the first try, but you usually have to repeat these steps a few times to completely remove the spray paint from the concrete.

Step 3: Scrub with a stiff bristle or wire brush

Here comes the fun part: the scrubbing. If you’re lucky enough to get all the spray paint off in Step 2, this doesn’t apply to you. However, once you start seeing progress and want to remove the paint completely, you will need to scrub the concrete with a stiff brush.

Don’t be afraid to apply some elbow grease. As you scrub, you should see the paint move and liquefy a bit. That’s a sign it’s working!

Step 4: Repeat the solution until it fades completely

Here we start repeating steps 1-3 to get the best possible result. Most solutions are safe to apply multiple times as long as you carefully monitor concrete erosion.

As long as your concrete can take it, you can reapply the solution to remove even the last stain of paint from your concrete floor or wall.

Step 5: Rinse the concrete thoroughly with hot, soapy water until clean

Now it’s time to thoroughly clean the concrete. This is an important part of the process, however, because if you leave paint thinner, nail polish remover, or any other thinner on the concrete, it will erode over time.

Therefore you must completely remove all residues of the thinner and the paint from your concrete. If you still have the pressure washer handy, I would recommend rinsing it at least twice with a soapy solution.

If you’re hand scrubbing, try to aim for 3-4 cleaning rounds to make sure you’ve got it all covered. When that’s all done, you can enjoy your newly stain-free concrete again!

Summary

Stains like spray paint on concrete wall and floor are often a major nuisance to home or business owners. If the surface is older or rough, it can be much more difficult to remove the paint. Since these types of surfaces are usually porous, this means that the paint gets into the cracks.

There are several types of stains in which you can find some that are easy to remove and require little effort. While at other times you may find some that are difficult to remove and require some effort. You can choose the most suitable method above based on your situation.
