How to Paint Trim

Painting the trim around your doors or windows is one of the many ways you can liven up your home's exterior. Use an exterior paint accent color that complements the main colors of your home or paint your trim white to embolden and emphasize the other colors. This guide will take you through the process of painting trim.

Tip: Use a drop cloth and tape the borders of all trim to avoid splattering paint. Angled paint brushes are best for painting sharp edges or tight corners.

Safety: If painting in an unventilated area, wear a face mask or respirator.
