How to Maintain Walls Made of Precast Concrete. Washing with pressure
One of the greatest ways to clean precast concrete fence panels is to use this technique. It’s quick and simple. You can buy or rent the equipment from your neighborhood hardware store. Since concrete cannot be harmed by pressure washing, you can clean your concrete fence without worrying about doing any damage.
Cleaning Your Hands
You can clean your concrete wall with just your hands, soap, and a cloth. Although this method will take longer than pressure cleaning, it’s a decent choice if you only want to clean a small portion of the wall or don’t have access to a pressure washer.
Prior to hand cleaning, make sure all surfaces are sealed to prevent more damage than good. Concrete walls respond quite well to this technique; just be sure to use the appropriate detergent. Use bacterial cleaners, alkaline cleaners, or pH-neutral chemicals; they are all quite mild and made to be applied to concrete walls.
Use the bacterial cleaners if your wall has been used as an outhouse by dogs or other animals. Those pee stains will be the easiest for them to remove.
If you want to clean up paint, move quickly and don’t wait for it to dry. You’ll need to consider employing more involved and expensive cleanup techniques if it dries. First, use fresh cloths to mop up any excess paint. After that, scrub as thoroughly as you can using water and a powder-based cleaner until the area is clean.
Sandblasting
As you might expect, this approach is more severe and ought to be saved for dire circumstances, such as graffiti or paint spills that have perished. You’ll probably need to contract with a business that specializes in sandblasting sealed concrete to do this. Doing this on your own is not advised. Sandblasting has the potential to destroy your concrete’s sealant if done incorrectly.
How to Maintain Walls Made of Precast Concrete. Scraping by Hand
Usually, this last technique is only applied when tar or another sticky material spills onto the concrete fence panels. Let the material dry first. If it’s tar, rapidly chill it with ice. After it cools, scrape out the tar or other material using a chisel or other flat scraper. To be completely clean, scrub.
Painting
Concrete walls can become so filthy at times that using any of the earlier techniques would not be worth the time and expense. Assume, for instance, if a group of taggers entered and covered the entire area with graffiti. In some situations, painting your fence can be your best bet. When painted, concrete fences look really good. The correct paint will cover the majority of issues and cling effectively to the concrete. Unlike wood fences, concrete fences require relatively little preparation before painting.
