Assuming you have a basic understanding of what retaining wall blocks are and why they’re important, we’ll move on to cleaning them. The first step is always to clear away any debris from the surface of the blocks. This can be done with a broom, rake, or even a leaf blower.
Once the surface is cleared, you can move on to washing the blocks with a garden hose fitted with a spray nozzle. Start at the top of the wall and work your way down, using a back-and-forth motion as you go. If there are any stubborn stains, you can try scrubbing them with a soft brush or sponge before rinsing.
- Sweep the retaining wall blocks with a broom to remove any dirt or debris
- Use a hose with a spray attachment to rinse off the blocks
- Mix up a solution of 1 part bleach to 10 parts water in a bucket
- Apply the bleach solution to the retaining wall blocks with a sponge or brush and scrub them clean
- Rinse off the blocks again with fresh water from the hose to remove any residue from the bleach solution
If you have mold growing on your retaining wall, it’s important to clean it off as soon as possible. Mold can cause serious damage to the wall and can also be a health hazard. There are a few different ways to clean mold off of a retaining wall. One way is to mix together equal parts water and bleach. Then, using a brush, scrub the moldy areas with the mixture. Rinse the area with water afterward.
Another way is to mix together one part vinegar and two parts water. Spray the mixture onto the moldy areas and let it sit for about an hour before scrubbing with a brush. Rinse afterward. If you have stubborn mold that won’t come off with either of these methods, you may need to use a power washer.
How Do You Clean Concrete Blocks?
Cleaning concrete blocks is a necessary step in preparing them for painting or sealing. Concrete is a very porous material, which means it can absorb stains and dirt easily. If you don’t clean the blocks before painting or sealing, the finish will not be as smooth or long-lasting.
There are several ways to clean concrete blocks. One way is to use a power washer with a detergent designed for concrete surfaces. You can also use a stiff brush and soapy water to scrub the blocks.
For tougher stains, you may need to use a pressure washer with an abrasive cleaner or rent a concrete surface cleaner from a hardware store. Once the blocks are clean, they need to be rinsed thoroughly with clean water. If you’re planning on painting the blocks, they should be allowed to dry completely before proceeding.
