Before installation, vinyl gutters are not painted. Instead, the vinyl is tinted using pigments, minimizes the appearance of scratches, and insuring that the color will not peel away from the gutter. However, this method does not prevent the vinyl gutters from fading or staining over time.
While replacing the gutters may be the most aesthetically pleasing option, if your vinyl gutters are still in good condition you should consider painting them. Not only will painting your vinyl gutters help save you money, but you’ll also save time when compared to removing and installing new gutters.
In order to achieve a professional paint job, two products are essential. The first is a liquid sanding product, which will allow the paint to adhere to the vinyl. The second is a flex additive, which is a solution added to the paint. A flex additive ensures that the paint will expand and contract as necessary, ensuring that it will not break away from the door and peel.
Step 1: Detach the downspouts from the exterior of the building. While you should not remove the actual gutters, removing the downspouts will actually save time during the painting process. Save any hardware you remove for reattachment at a later date.
Step 2: Clean the gutters and downspouts with a solution of TSP and warm water. Use a medium bristled nylon scrub brush to apply the solution, and scrub away any resistant stains and debris. Use a garden hose to rinse the vinyl gutters and downspouts thoroughly. Allow everything to dry before proceeding.
Step 3: Use liquid sanding solution to remove the glossy surface of the vinyl siding. While usage instructions for liquid sanding solutions vary, most require you to apply a thin layer with a brush, wait a few minutes, and then remove the sanding solution with a rag. Keep in mind that you may have to work in sections to avoid leaving the sanding solution on the vinyl gutters for too long.
Step 4: Mix in the flex additive to the paint you want to use. Pay particular attention to the ratio of flex additive to paint. Avoid storing the paint with the flex additive for any length of time.
Step 5: Apply the paint with a high quality exterior brush. Use a small brush for work where control is essential, and a larger brush to cover large areas, such as the inside trough and outside edge of the vinyl gutter.
