After pouring the stripper, use a squeegee to spread it out over the designated area. Ensure to spread correctly around the area that you want to remove the sealer.
Step 3: Allow the chemical stripper to set for at least 15 minutes. This step is really vital as it allows the stripper to get to work and weaken the asphalt sealer. If you don’t let the chemical stripper set in, the sealer will be tough to remove.
Besides, you should apply it evenly as too much of it may runoff. Furthermore, you should only apply to the areas you want to remove the asphalt sealer and not the entire concrete.
Step 4: After the chemical stripper has set in, it’s now time to get messy. You will have to obtain a paint scraper to remove both the chemical stripper and asphalt sealer. As you get rid of the sealer, you should see rough-looking concrete. Watch out for the splashes and collect the scrapings for proper damping.
In some situations, the asphalt sealer may be stubborn to get off the concrete. If that’s the case, you should add more chemical strippers to the area and give it more than 15 minutes. Repeat scraping, and it will get off. But if it refuses for the second time, you may have to get in touch with a professional contractor to deal with it.
Step 5: If you have successfully removed the sealer, it’s time to rinse the concrete. With the help of a pressure washer or garden hose, spray the water on the concrete before applying a cleaning solution or detergent. It’s best if you use a powerful pressure washer. A pressure washer with a PIS of about 2700 is perfect for such a job.
Step 6: Next, mix 50 percent warm water and 50 percent soap solution or detergent. Pour this mixture on the concrete and thoroughly scrub it. This will ensure that any loose sealer left on the surface is removed. Scrub the concrete for about 10 to 15 minutes. You can now rinse the concrete using your pressure washer or garden hose.
Ensure no sealer or chemical stripper remains behind, as they may affect how effective your sealer works. If possible, rinse as many times as you can to have clean concrete.
Step 7: When you’re done rinsing the concrete, allow it to dry before applying another sealer or a finish of your choice. Depending on the weather, the concrete may dry faster or slow. It’s best if you conduct this duty when there’s the sun.
