The process of cleaning render can be a bit daunting, but it’s important to get it right if you want the best results. The good news is that render cleaning isn’t hard and by following these steps you’ll know how to get the best results every time:
Be prepared for Render Cleaning
Before you start the render cleaning, make sure you have everything that you need on hand. This includes:
- A clean bucket and brush (or similar tools)
- A scraper, if necessary
- A ladder or step stool to reach high windows
- A pressure washer
Step 1 – Premade chemical or homemade paste
The first step to cleaning the render is to apply a chemical solution to it. You can use either a premade chemical or make your own. If you choose to go with the premade option, read the instructions on the packaging carefully before using it and always wear gloves when applying.
If you are going down the homemade route, mix together equal parts bicarbonate of soda (baking soda) and water in an old bucket or container that has been cleaned thoroughly beforehand. This mix will help restore brightness to the colour. It’s not too harsh though so you may need a more specialised render cleaning service by professionals for more stubborn dirt and grime.
Use an old brush or sponge to apply this mixture evenly over all surfaces of your render until they’re covered completely by white froth; this will help lift dirt away from them during washing later on! Leave this mixture on for at least 30 minutes before proceeding to step 2 below.
Step 2 – Clean brush and bucket of clean water
Use a clean brush and bucket of clean water to brush any particularly stubborn areas of dirt to work in the chemical solution. Then rinse the brush in clean water, and leave it to dry.
Step 3 – Apply a cleaning agent
Once you’ve got the render clean, it’s time to start applying your chosen cleaning agent. There are several different ways you can do this:
Brush – A brush is a good choice if you want to get into all of those nooks and crannies that other tools won’t reach. You’ll need to use a soft-bristled brush with stiffer bristles for tougher stains, and softer ones for more delicate ones (like grease). You should also make sure that there are no loose hairs or threads hanging out; these can damage your render as well as yourself!
Sponge – This is another great option if there are lots of hard-to-reach places on your wall or roofline, just be careful not to leave pools behind when rinsing off excess liquid! Sponges come in different sizes so make sure yours fits comfortably within reach before purchasing one online.
Step 4 – Leave to dwell
Once you’ve scrubbed the render, it’s time to leave it to dwell. This is the most important part of cleaning your render because it allows any dirt that may have been loosened by the process to be absorbed into its pores.
Leave your brush on a tray or in a bucket filled with clean water and let it soak for at least 10 minutes, but longer if necessary – up to 30 minutes if you want an extra thorough clean.
Step 5 – Pressure wash off with a pressure washer set to low pressure.
You can use a pressure washer, but only if you’re careful. Pressure washers are not the same as garden hoses, and they have much more power than even your most powerful hose. If you don’t use them with care, they can cause damage to your render.
When using a pressure washer for cleaning render, always set it to low pressure and use it in a well-ventilated area.
If you follow these steps you will now have the best results when cleaning your render.
To summarise, the first thing you need to do is prepare your surfaces for cleaning. You can do this by using a power washer or pressure washer and spraying down all of the renders with water. This will help remove any dirt, grime or moss from the surface so that it’s easier for them to be cleaned off later on in the process.
Next, use a pressure cleaner with an attachment that has been designed specifically for cleaning render (this will have bristles on one side). Use this attachment to scrub at each area where there are imperfections in your render work until they have been removed completely from view – remember not too hard though as you don’t want any marks left behind!
Finally, take another look over all areas again just in case anything else might have appeared since we started working on them earlier today; if so repeat steps 1-3 again until no more marks remain visible after inspection
By following these steps, you will be able to get the best results when cleaning your render. But, if you’re not confident about using chemicals, or don’t have access to the right equipment then you can always hire a professional render cleaning service to come and do the job for you. The benefit of hiring a professional as well is they can apply a preventative sealing solution once the render is clean.
