Paint stains that you accidentally dripped onto driveways or garage floors so that your cement car can stay there forever. Although removing paint stains from cement is difficult and time consuming, you can do it with patience and use the right product. The following guidelines also help you remove the most stubborn paint on your yard or garage.

Steps

Method 1 of 3: For small paint stains

1. 

   Prepare the cement surface. Use a brush or vacuum cleaner to remove all dirt or deposits. If possible, use a scraper or brush to remove some of the soft paint from the cement.

2. 

   
   
   Apply chemical paint remover to the surface of cement. What paint remover you use will depend on the type of paint to be removed, such as water based paint or oil based paint. If in doubt, use a remover used to remove oil-based paint.

3. 

   Let the bleach work. Check the manufacturer's instructions on the product box. It may take 1-8 hours for the product to take effect. Some products only take a few minutes.

4. 

   
   
   Rub the cement. Use a iron brush or scraper to remove the softened paint. Or you can use a pressure washer to scrub outdoor cement surfaces, like driveways or yards.

5. 

   Repeat steps as needed. In some cases, you may need to apply the paint remover 2-3 times if necessary to completely remove the paint stain on the cement.

6. 

   
   
   Clean the cement surface. Use a pressure washer to remove all traces of paint remover. Once dripping paint has been removed, cleaning the cement surface can help avoid leaving white marks on the surface. advertisement

Method 2 of 3: For stubborn paint stains

1. 

   Create absorbent paint remover mix. Prepare materials. You will need a paint remover. If you remove paint in a well-ventilated area (outside or in a separate garage, with the door open), you can use a bleach product that contains methylene chloride. This helps the paint removal process much faster. Also, be prepared with a respirator when handling paint removal products.
   • Need to prepare absorbent material. Fine clay powder is most effective. If you don't have a fine clay powder, you can crush your cat's sanitary sand into a powder.
   • To complete the cleaning, you need to prepare a stiff brush and scouring powder.

2. 

   Mix the paint remover with the absorbent material. Make a clay or sand mixture for your cat. Depending on the thickness of the cleaner, you may not need to use too much absorbent. Absorbent material helps to absorb the paint from the cement, making it easier to remove.

3. 

   Apply the mixture. Apply a thin layer of the paint remover mixture with the absorbent material to the cement. Allow time for the paint remover to take effect. Depending on the chemicals you use, the waiting time can range from about 20 minutes to a few hours.
   • In the process of waiting, continue to apply more paint thinner mixture on the surface of the first mixture to keep the ingredients active.

4. 

   Shave the mixture. Paint thinner will do the bulk of the job. From here, you can use a hard plastic scraper to scrape the paint from the cement. Apply one more layer of the mixture if the paint remains on and repeat the process.

5. 

   Rub paint. Use a stiff brush, scouring powder and water to scrub the surface of the stripped cement to remove residual paint dust. Rinse off the cleansing powder mixture and continue scrubbing with the brush until the paint is gone. advertisement

Method 3 of 3: For widespread paint stains

1. 

   Consider firing (spray) sodium carbonate. Determine whether using a catapult (sprayer) is suitable for your needs. If the coating is over a wide surface, a sprayer may be a better option than a paint remover mixture. One form of shot that you can use is a shot of sodium carbonate, which uses baking soda as a cleaning agent. The sodium carbonate firing method is also much more environmentally friendly than chemicals and does not damage the underlying cement surface.

2. 

   Prepare the lucky machine. To shoot sodium carbonate, you need a catapult. You can go to the mechanic to rent the machine. In addition, you need a special sodium bicarbonate preparation. The baking powder bought from the grocery store is too fine to use to shoot sodium carbonate. You can find sodium carbonate powder from dispensers rentals or order them online.
   • Most standard sandblasting machines cannot function with sodium carbonate. You will need a special firing machine to shoot sodium carbonate.

3. 

   Shoot the painted sticky surface. Shoot slowly and hold the nozzle about 0.45 m above the ground. Be sure to wear a respirator to avoid inhaling dust. Move the nozzle evenly back and forth over the painted surface to ensure no missed paint is left.
   • If sodium carbonate is shot near plants, be sure to avoid splashing excess particles on the plants. High pH sodium carbonate can cause flowers and shrubs to brown and die.
   • If you need to remove a lot of paint, you should consider hiring an expert to use a sprayer. You yourself may have a lot of problems with the amount of firing material needed and the size of the firing machine.

Advice

• Some bleaching products can lighten the place where cement is processed. Therefore, you need to test first on a small surface and proceed when you are satisfied with the results.
• Paint remover should be applied to cementitious surfaces that are not warmer than room temperature.
• If all else fails, you should buy paint of your choice and match the cement surface to paint over the entire surface.
• If you are removing paint from a large surface, divide it into small areas to make it easier to remove.
• Wear rubber boots and gloves, and eye protection or goggles.
• Follow the manufacturer's instructions on the package when preparing and using paint removal products. Some chemicals may need to be mixed or diluted.
• Contact the paint manufacturer (if known) for recommendations on the best paint removal products.
• Apply the polish remover to the cementitious surface and rub it vigorously.

Warning

• Apply the polish remover to the cementitious surface and rub it vigorously.
• Use caution if using acid or acetone paint removers. Wear protective clothing and wash it immediately after using paint remover. * Products containing methyl ethyl ketone (MEK) are very flammable, smoke-emitting and toxic.
• Use a paint remover in a well-ventilated area. If you remove paint from your garage or basement floor, you will need to open all windows. Some paint remover products may be recommended for outdoor use only.
