Long-Lasting: Silicone render is highly durable, and when applied correctly, it can last up to 25 years or more.

Disadvantages of Using Silicone Render

Cost: Silicone render is typically more expensive than other types of render. However, it is worth the investment due to its durability and low maintenance requirements.

Disadvantages

  1. Prone to Staining: K render is prone to staining if not properly maintained, particularly in areas with high pollution levels or exposure to dirt and debris.
  2. Limited Water Resistance: While K render has some water repellency, it is not as water-resistant as other renders, such as silicone render.

Best Applications for K Render

K render is an excellent choice for modern and traditional buildings and is particularly well-suited for properties requiring a fast application process. It is ideal for buildings in urban areas or high-traffic locations, as it is resistant to cracking and can withstand exposure to pollution and dirt.

It is also a popular choice for properties requiring various colours and textures. Overall, K render is best suited for properties that require a durable and versatile finish.
