How to Clean External Wall Cladding
There are many different types of external wall cladding including solid aluminium and aluminium composite panels, timber cladding, steel, concrete, brick and more. The one thing they all have in common is that over time they will start to feel the effects of the elements.
It’s important to regularly clean your cladding to ensure it’s free from dirt, mould, stains and other contaminants. Over time, they can build up on the surface and damage your cladding, affecting its durability and useful life. You may even need to replace it earlier than expected because it has not been properly cared for.
Additionally, keeping your cladding clean will mean your home’s exterior shines. If you’re selling your home, this can be a simple way to improve curb appeal. And even if you’re not, it’s a great way to show that you take pride in your home.
Further, if you’re intending to complete any maintenance work on your cladding, like painting, staining or repairs, having a clean surface is essential. If you’re going to put in the time repainting your home, you need the surface properly cleaned and prepared to ensure high-quality and long-lasting results.
How to Clean External Cladding
Different cladding materials may require different cleaning techniques or specific cleaning products for best results. It’s worth noting that this is just a general guide. Some of the steps or equipment may not be suitable for all types of cladding. Before starting, it’s always worth checking the manufacturer’s cleaning recommendations.
But if you’re looking for a general cleaning guide, here’s what we recommend.
- Gather materials
Start by getting everything you need ready. This helps to ensure the job gets done quickly and you don’t find yourself having to improvise halfway through the task.
You’ll need the following:
- Soft-bristled brush or broom
- Bucket of water
- Suitable cleaning solution
Choose a cleaning solution that is designed for your type of cladding. It can help to check for any information from the manufacturer.
- Remove dry dirt
Using your brush or broom, remove any loose dust, dirt and other debris, like rain spots and bird droppings. Take care not to brush too aggressively as this may damage the cladding. If you can’t get something to come off, don’t worry. The next couple of steps should take care of it.
It’s recommended to remove as much dirt as you can before the next step. This is to ensure that when you start using water, you don’t just end up turning the dust and dirt to mud. That can make getting your cladding clean far harder.
- Wet cladding
Using your hose, spray the cladding to remove any remaining dirt. If you’re having trouble getting the dirt to move, you can use a power washer to clean your cladding. However, you need to be careful to not damage the cladding. Make sure it’s on a low setting and you keep a good distance between the power washer and the cladding. If not, the pressure of the water may chip, splinter or dent the cladding.
- Take care of stubborn stains
If there are still stains, mould or dirt left, there’s another step you can follow. Mix up your cleaning solution in your bucket of water. Wet your sponge with the solution and gently scrub at any problem areas. This should remove any remaining marks and dirt.
- Rinse and let dry
Finally, use your hose to clean off any cleaning solution left on the cladding. If left there, it can cause damage to the cladding, like ruining the finish. Then you just need to let the cladding dry.
It shouldn’t take more than a few hours to clean your external cladding. And the results are well worth it — your home will look great, and your cladding will last longer.
