To create a good-looking exterior window trim quickly, assemble the casings, attach the sill to the legs with glue and 21⁄2-in. galvanized finish nails, prime the end grain, and fill nail holes with solvent-based wood filler like PL FI:X. Flashing a window is a way to seal the area around the window from water infiltration while allowing water that gets behind the trim boards to exit the wall structure.

Factory-focused trim ideas can provide stylish functionality and protect windows from the elements. You can install window trim on stucco surfaces, which enhances aesthetics and weather. Fasten exterior trim with framing nailer, finish nailer, staples, hand nails, or exterior glue such as Titebond III. Dry-fit the pieces before assembly and use a bar clamp to hold things together.

Corrosion-resistant nails or screws with a minimum length of 1.5 inches, blunt point, and full round head are also suitable. Aluminum angle is recommended for its durability and ease of use, which can be sanded down and painted in the same color as your gutter to highlight it.
