Why Use Silicone Sealant?

When installing your aluminium grate, using a neutral cure silicone sealant over other alternatives, such as glue or grout, is essential. Silicone sealant provides several advantages for aluminium products, including:

 

  • Flexibility: Utilising silicone sealant ensures that it remains resilient and durable, with the ability to flex and adapt to any changes in the surrounding materials. In contrast, grout is prone to cracking, leading to potential leakage or damage to your grates and end caps.

 

  • Compatibility: Silicone sealant is the best when used in aluminium products without causing any adverse effects. Glue and grout can contain chemicals that may reverse the anodising process, diminishing the quality and appearance of your grates.

 

  • Water Resistance: Silicone sealant forms a secure barrier against water, ensuring watertight seals and preventing unwanted leaks.

 

Preparing Your Grate for Installation

 

Before installing your aluminium grate and sealing the end caps, the surface should be cleaned thoroughly to remove dirt, dust, or debris which may hamper the bonding process. It should also be completely dry to prevent moisture from affecting the sealant’s ability to adhere properly. Guaranteeing these steps will help ensure a successful installation and a long-lasting seal. This ensures a secure bond between the silicone sealant and the aluminium.

  • STEP 7: According to the product instructions, allow the silicone sealant to cure for the recommended time. This can vary, so check the specific instructions for your chosen sealant.
