Maintenance Tips for Long-lasting Acrylic and Cement Renders
Ali Hamad • February 28, 2025
Both acrylic and cement renders are excellent choices for enhancing your Sydney home’s exterior, but maintaining them is key to keeping them looking fresh and lasting longer. Sydney’s unique climate—ranging from heavy rains to strong UV exposure—can take a toll on rendered surfaces if not properly cared for. Alcore Rendering, a trusted provider of rendering services in Sydney, shares practical tips to help you maintain your render and protect your investment.
Routine Cleaning – Keep Your Render Looking Fresh
- Dust and Dirt Removal: Over time, dust and dirt can build up on rendered surfaces, dulling their appearance. Use a soft-bristle brush or a low-pressure hose to clean your walls gently. Avoid high-pressure washing as it can damage the surface, especially for cement render.
- Stain Removal: For tougher stains, use a mild detergent diluted with water and a soft sponge. Test the solution on a small area first to ensure it doesn’t affect the render’s finish. Alcore Rendering recommends avoiding harsh chemicals that can strip the surface.
- Frequency of Cleaning: Sydney’s coastal homes may require more frequent cleaning due to salt deposits, while urban properties might accumulate more dust. Aim to clean rendered surfaces every six months to maintain their appearance.
Protecting Your Render Against Sydney’s Climate
- Rainproofing and Moisture Management: Heavy rains in Sydney can lead to moisture buildup, especially for cement renders. Check your gutters and downpipes regularly to ensure proper drainage and prevent water from pooling near walls. Applying a water-resistant sealant can also add an extra layer of protection.
- Managing UV Exposure: Sydney’s strong sun can fade colours over time, particularly on acrylic renders. Consider applying a UV-resistant topcoat to maintain vibrant colours and prevent cracking caused by heat exposure.
- Dealing with Seasonal Changes: Both acrylic and cement renders can expand and contract with temperature shifts. Inspect your walls for hairline cracks after extreme weather and have them repaired promptly by professionals like Alcore Rendering to prevent further damage.
Conclusion
Maintaining your acrylic or cement render is essential for keeping your Sydney home looking its best and ensuring its longevity. With simple routine cleaning, climate-specific precautions, and timely repairs, you can protect your rendered surfaces from damage and enjoy their benefits for years to come.

All About Rendering

Thinking of getting your home rendered but not sure if winter is the right time? You’re not alone. A common misconception among Sydney homeowners is that rendering can only be done in summer or warmer months. At Alcore Rendering, we work year-round and understand how to adapt to the seasons, especially Sydney’s milder winters. In this blog, we’ll break down the ideal conditions for rendering, why winter isn’t off-limits, and how we ensure quality results no matter the season. Does Weather Really Affect Rendering? Yes, but not always in the way people assume. While render products do need time and the right environment to cure properly, Sydney’s winter conditions are usually quite suitable. Here's what matters most during a rendering job: Temperature : Most render types cure best between 10°C and 30°C. Sydney’s winter days generally fall within this range. Rain : Wet conditions can delay rendering, as render needs a dry surface to bond and cure. That said, experienced teams like Alcore Rendering plan around rain effectively. Humidity and drying time: Cement render cures slower in winter, which can actually reduce the chance of cracks forming from overly fast drying. So, while weather is a factor, Sydney’s winters are mild enough to allow rendering projects to go ahead without major concerns, especially when managed by the right team. Benefits of Rendering in Winter Believe it or not, winter comes with some surprising advantages for rendering in Sydney: Ideal curing conditions: Cooler temperatures give the render more time to bond and settle, reducing the risk of cracking - particularly for cement render Greater availability: Winter is often a quieter season for tradies, which means more flexible booking windows and quicker turnaround times. Get in before spring selling season: If you're planning to list your property in spring, having the rendering done in winter means your home will be looking its best when the market heats up. What Alcore Rendering Does Differently in Winter At Alcore Rendering, we take additional steps during the cooler months to ensure every project stays on track and delivers a high-quality result: Weather Monitoring: We plan jobs around Sydney’s forecast to avoid rainy days and adjust drying times if needed. Modified Products: For winter projects, we may use acrylic renders or additives that are better suited to cooler temperatures and damp conditions. Flexible Scheduling: If unexpected rain hits, we communicate early and work with you to find the best reschedule window. Extra Care in Surface Prep: In winter, we take extra time to ensure surfaces are bone dry before application, especially in shaded or south-facing areas that hold moisture. When Should You Wait? While Sydney winters are usually workable, there are a few rare cases where it may be better to delay: Extended rainy spells with no dry windows for application or curing. Extremely damp, shaded walls that can't dry out adequately between coats. Properties located in higher-altitude areas where winter temps may drop below 5°C overnight. If any of these apply to you, Alcore Rendering will be honest and advise the best plan, because quality comes first. Rendering your home in winter is absolutely possible in Sydney, and in many cases, it’s actually a great time to get started. With proper planning, the right products, and an experienced team like Alcore Rendering, you can achieve a flawless result without waiting for summer.
