When considering the protection and visual enhancement of your building's exterior, look no further than our range of JUB silicone renders. These thin-coat render finishes, developed from a combination of silicone and other polymeric binders, bring more than just a textured or smooth appearance to your façade; they come with a host of advantages. To ensure a successful application of our JUB silicone renders, follow this comprehensive step-by-step guide.
Before diving into the application process, it's important to prepare the surface thoroughly.
Here's what you need to do:
Proper surface preparation is vital for achieving an even and long-lasting finish.
Select an appropriate primer based on the type of surface you're working with:
Apply the chosen primer evenly to the surface using a paintbrush, masonry brush or a long-fibre fur or textile paint roller. Allow the primer to dry thoroughly before moving on to the next step. The drying time for Unigrund and Akrinol SuperGrip is on average 12 hours. Depending on weather conditions drying time can vary.
Now, it's time to apply the JUB silicone render finish, a critical step that requires attention to detail and precision. Here's detailed instructions on how to execute this stage effectively:
Mix Thoroughly: Before application, thoroughly mix the render finish with an electric mixer. Ensure that the mixture has a uniform consistency. If necessary, you can dilute it slightly with water, but be cautious not to overdo it. Generally, a maximum of 100 ml of water per container is recommended for dilution. Proper mixing is crucial to achieve a smooth and consistent application.
Colour Shade Check: It's essential to verify that the render finish's colour shade matches your requirements. Additionally, it's a good practice to equalise the render finish. This means eliminating any slight differences in colour shade between individual buckets. To do this, stir the contents of four buckets together in a larger container of suitable size. By maintaining uniformity in colour, you'll ensure a seamless finish.
Application Method: The JUB silicone render finish can be applied using two primary methods - manual application with a stainless steel smoothing trowel or application by spraying. Both methods have their advantages, and the choice depends on your preferences and project requirements.
Smoothing: After applying the render finish, it's essential to smooth the surface promptly. This step is crucial for achieving an even and visually appealing finish. Here's how to do it:
Efficient Working: During the application process, it's essential to work as swiftly as possible without interruptions. Begin at one corner of the wall and progress steadily toward the opposite corner. This approach ensures a continuous and consistent application.
Choose suitable weather conditions for application. Ensure that both the air and wall surface temperatures are between +5 ºC and +35 ºC, with relative air humidity below 80%. While protecting the façade from sun, wind and rain with scaffold netting, refrain from working in the cases of heavy rain, fog or wind conditions (wind speeds of ≥30 km/h) despite protective measures.
Clean your tools with water immediately after use. Dried stains cannot be removed. Dispose of waste materials responsibly, following local regulations. Safety precautions include wearing protective glasses or a mask when spraying the render finish.
By adhering to these comprehensive steps, you can achieve a successful application of our JUB silicone renders. For more detailed information on our silicone renders, feel free to explore our website or
