Understanding the Different Types of Render: A Guide to Effective Cleaning Techniques
31st July 2023
Render is a popular choice for exterior walls due to its durability and aesthetic appeal. However, over time, dirt, algae, and other contaminants can accumulate, making the render look old and worn. To maintain the pristine appearance of your property, it is important to understand the different types of render and the most effective cleaning techniques for each.
1. Sand and Cement Render
Sand and cement render is the most common type of render used on residential and commercial buildings. It is a mixture of sand, cement, and water that is applied to the exterior walls. This render is hard-wearing and can withstand harsh weather conditions.
Cleaning Technique: Soft Washing
Soft washing is the most suitable cleaning technique for sand and cement render. It involves using low-pressure water and a specialized cleaning solution to gently remove dirt, algae, and other contaminants. Soft washing is recommended to avoid damage to the render surface.
2. Lime Render
Lime render is a traditional render made from lime, sand, and water. It is commonly used on older buildings and properties with historical significance. Lime render has excellent breathability, allowing moisture to escape from the walls.
Cleaning Technique: Wet Cleaning
Wet cleaning is the preferred method for cleaning lime render. It involves using a low-pressure water spray to wet the render surface and then gently scrubbing with a soft brush. This technique helps to remove dirt and algae without causing any damage to the render.
3. Acrylic Render
Acrylic render is a modern render that is made from a mix of acrylic polymers and other additives. It is popular for its flexibility and ability to resist cracking or peeling. Acrylic render comes in a wide range of colours and finishes, making it a versatile choice for exterior walls.
Cleaning Technique: Pressure Washing
Pressure washing is the most effective cleaning technique for acrylic render. It involves using high-pressure water to remove dirt, grime, and algae from the surface. However, it is important to use a low-pressure setting and a wide nozzle to prevent damage to the render.
Understanding the different types of render and the appropriate cleaning techniques is essential for maintaining the appearance and longevity of your property.
