Installing Exterior Window Trim. The Idaho Painter Way.
What happens here
Using a caulk gun, apply caulk (such as Power Seal All-in-one) along all seams where the new trim meets the window frame and the house siding. Immediately after applying the caulk, use a wet sponge or your finger to smooth out the caulk bead, creating a clean, watertight seal. Then, fill all countersunk nail holes with a patching compound or wood filler, ensuring a smooth surface.
Goal: Seal the new trim against moisture and fill imperfections for a smooth surface ready for paint
