Cleaning and Priming

When painting aluminium windows, it’s essential to start with a clean and well-primed surface. This will ensure the paint adheres properly and provides a long-lasting finish.

Thoroughly Cleaning the Surface

Before you begin, it’s crucial to thoroughly clean the aluminium window frames. Use a mild detergent and water to remove any dirt, grime, or grease. You can also use a specialised aluminium cleaner for tougher stains. Rinse the frames thoroughly and allow them to dry completely before moving on to the priming stage. Remember, a clean surface is essential for the primer and paint to adhere properly.

Applying Primer for Aluminium

Once the surface is clean and dry, it’s time to apply the primer. Choose a high-quality primer specifically designed for aluminium surfaces. This will help the paint adhere and provide an extra layer of protection against the elements. Apply the primer evenly, using long, smooth strokes to ensure full coverage. Allow the primer to dry completely before moving on to the next step. This step is crucial for ensuring the longevity and durability of your paint job, so don’t rush the process.
