In the beautiful and varied climates of the UK, homeowners take great pride in the upkeep of their homes. One such key aspect of many UK homes is the render on the exterior walls. But as picturesque as it can be, this render requires regular maintenance to keep it looking pristine. Over time, factors like the environment, algae growth, and pollution can take their toll on a house’s render, leading to a tired and worn appearance. This comprehensive guide will take you through the process of how to clean render on a house, ensuring it stays as charming as the day it was first applied.
What is Render and Why Does It Get Dirty?
Render can come in many different forms which include K-Rend, Sto-Rend, Weber, Parex, cement render and pebble dash. Its purpose is twofold: to provide an aesthetic finish to a building and to offer protection from the elements. Given the UK’s often unpredictable weather – from scorching summer days to icy winter spells – render has become a staple in many homes.
However, due to its porous nature, render is prone to gathering dirt. Environmental pollutants, car emissions, and general airborne particles cling to the render. Add to this the wet weather, and you have a perfect breeding ground for moss, algae, and mould. These not only detract from your home’s appearance but, if left untreated, can lead to long-term damage.
Essential Tools for Cleaning Render
Before embarking on this cleaning journey, it’s crucial to be well-equipped. Here are the must-haves:
- Soft-bristled brush: A manual tool for dislodging surface dirt.
- Low-pressure power washer: Too much pressure can erode the render, so stay on the side of caution.
- Render cleaning solution: Opt for eco-friendly options to minimise environmental impact.
Step by Step: Bringing Life Back to Your Render
1. Start with an Inspection
Every good cleaning begins with an evaluation. Examine the render for cracks, chips, or any other forms of damage. These need addressing before cleaning commences.
2. Setup and Safety
Remove potential obstructions – be it garden furniture, vehicles, or potted plants. This not only makes the process smoother but prevents accidental damage.
3. Dry Brushing is Key
With your soft-bristled brush, gently sweep across the rendered surface. This preliminary step ensures that you’re not just spreading the dirt around when wet cleaning starts.
4. Bring in the Cleaning Solution
Following the specific instructions, apply the render cleaning solution. Let it soak for a while, allowing the active ingredients to break down stubborn grime and biological growths.
5. Time to Rinse
The low-pressure power washer comes into play here. Begin at the top and gradually make your way down, ensuring all cleaning solution is washed away.
6. Double-Check Your Work
It’s common to miss a spot or two. After the primary wash, inspect the surface again. Should you find lingering stains, a second round of cleaning solution and rinsing may be necessary.
7. The Waiting Game
After the washing, the render needs ample time to dry. The duration can vary based on weather conditions, but patience is essential.
Expert Tips to Keep Your Render in Prime Condition
Biannual Checks: Instead of waiting for visible dirt, schedule biannual inspections. Catching issues early can save much effort later.
Stay Gentle: Render can be a delicate material. Gentle cleaning methods are always preferable.
Use Biocide Treatment: To ward off organic growths for longer periods, consider applying a biocide treatment after cleaning.
