Stucco is a great alternative to your standard siding, brick or stone walls.
Unfortunately the textured surface of stucco can act as a magnet, attracting dust and dirt from all over.
This can turn a once beautiful wall into a shadow of its former self.
Luckily, the power of a pressure washer can blast away this unappealing buildup, making your walls look brand new again.
Before doing any power washing, you need to make sure there aren't any cracks or chips in the stucco. If there are, water can seep through them, potentially leading to structural damage down the line.
All cracks and chips should be patched and given enough time to dry. You should let patches dry for about a week.
When washing stucco, it's best to divide the project up and work from section to section.
You're going to need a good detergent in order to give your stucco the shine it once had.
Apply the detergent from the bottom up and allow it 5-10 minutes to fully work.
The detergent needs to be wet to work, so you will need to add water as needed while the detergent is doing its job.
When cleaning heavily stained areas, use a rotating scrub brush attachment. This will make sure the stains are properly removed.
A quality rotating wash brush will make cleaning these difficult stains a breeze, getting the job done faster than ever before.
Rust must be removed by hand, using a brush and a rust removing product.
When rinsing always make sure you are using a low pressure spray pattern and hit the wall at a 45 degree angle.
Because of the delicate nature of stucco you need to always hold the spray nozzle a minimum of 24 inches away from the surface.
Work from the sections that you identified earlier, and rinse off the detergent and residue from the top down.
