When exterior paint starts to peel, it means the paint has not adhered properly to the surface. One reason for this is the application of the paint in damp weather conditions; paint can't stick to damp wood. A dirty or greasy surface will also cause paint to peel. To remedy the situation, remove all peeling and bubbling paint, and prime and repaint the area in dry weather conditions.
Scrape away all peeling paint using a wire brush. Use a handheld rotary tool or oscillating tool with a sanding accessory to smooth the surface, especially where scraping one paint layer has also scraped off an existing layer underneath.
Wipe the area thoroughly with a rag and household cleaner to free the area of all dirt and oil. Wait for the area to dry completely.
Fill holes or gouges with wood filler or painter's caulk using a putty knife and rag. Wait for the filler or caulk to dry thoroughly. Sand the filler or caulk to smooth it out using sandpaper, a handheld rotary tool or an oscillating tool.
Brush or roll quality primer onto the area in good weather conditions. This generally constitutes 55 degrees Fahrenheit or warmer, but always follow the paint manufacturer's instructions on the can. Wait for the primer to dry fully. Brush or roll one or more coats of exterior paint over the primed area in good weather conditions, waiting for the paint to dry thoroughly between coats.
