0 Lin Raleigh, NC on Mar 25, 2011 Like Clip The paint on the floor of my front porch which is made of treated tongue and groove is peeling. What is the best way to remove the peeling paint and how should I prepare the wood before repainting? Should a primer be put down before repainting? 1 Comment James A Roswell, GA Pressure washing should remove the flaking. A scraper might be needed. Sand, a power sander saves a lot of work. Then use an exterior primer before you paint. NOTE: You can drag and drop your photos to reorder them Required Comment Saving...
