Sunlight degrades the unfinished wood surface thus it will never hold paint as well as fresh wood. Once primer has dried trim is ready repainting exterior trim looking brand new. A very good high bonding primer on all bare wood surfaces.

The high pressure of the sprayer can knock those old boards loose and infuse the bare areas of wood with water. Priming all bare wood caulking fillers sealing trim allowing primer to properly dry. Another key step preparing trim for paint is priming. Sills and other horizontal surfaces peel because water runoff is slow and in the meantime can work its way through any crack in the paint.

Do keep in mind that old paint may contain lead and proper precautions should be taken when removing those old fragments of paint. Heat from sunlight also drives the moisture into the wood. Just look at the same trim after one coat of the primer and zero scraping or sanding. However a four to five inch wide brush usually works best.

To effectively apply primer use a paint brush and apply in a left to right right to left sweeping motion. Filling gouges with wood fillers on older surfaces. Scrape sand and recoat these highly vulnerable areas as soon as peeling paint begins.

Step 4 paint your wooden clapboard siding. Paint tends to peel or flake near joints between dissimilar materials think siding and trim window frames and glass etc. Sanding filler caulking edges where trim meets another substrate allowing to dry. This is where water seeps into cracks and soaks into the wood causing the paint to peel.
