How to paint peeling wood siding. Your brush size is dependent upon the size of your siding. Just look at the same trim after one coat of the primer and zero scraping or sanding. With low vocs this water based binding primer is three times thicker than regular primers and locks down and hides peeling weathered surfaces to create a smooth white finish for your top coat. Once primer has dried trim is ready repainting exterior trim looking brand new.
Heat from sunlight also drives the moisture into the wood. Cutting digging out rotten wood before painting over old paint. A very good high bonding primer on all bare wood surfaces. Paint tends to peel or flake near joints between dissimilar materials think siding and trim window frames and glass etc.
However a four to five inch wide brush usually works best. Unfinished siding exposed to several weeks of sunlight before painting needs to be sanded. Sanding wood fillers before priming older paint coatings. The high pressure of the sprayer can knock those old boards loose and infuse the bare areas of wood with water.
Another key step preparing trim for paint is priming. Scrape sand and recoat these highly vulnerable areas as soon as peeling paint begins. Priming all bare wood caulking fillers sealing trim allowing primer to properly dry. To effectively apply primer use a paint brush and apply in a left to right right to left sweeping motion.

This is where water seeps into cracks and soaks into the wood causing the paint to peel. Do keep in mind that old paint may contain lead and proper precautions should be taken when removing those old fragments of paint. Sunlight degrades the unfinished wood surface thus it will never hold paint as well as fresh wood. Filling gouges with wood fillers on older surfaces.
