How to Apply Stucco on Soffits

If you plan to finish a basement for use as a living space, soffits can help minimize the appearance of pipes and duct work along the basement ceiling. Wood soffits can give your basement living area a clean, finished look. Although homeowners typically paint or stain soffits, you can also apply stucco to wood soffits to customize your basement space. Applying stucco to wood is a relatively straightforward task; but it can also be a time-consuming process.
