How to paint peeling wood siding.

Cutting digging out rotten wood before painting over old paint. 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. Step 4 paint your wooden clapboard siding. Priming all bare wood caulking fillers sealing trim allowing primer to properly dry.

The high pressure of the sprayer can knock those old boards loose and infuse the bare areas of wood with water. 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. Your brush size is dependent upon the size of your siding.

Unfinished siding exposed to several weeks of sunlight before painting needs to be sanded. This is where water seeps into cracks and soaks into the wood causing the paint to peel. Filling gouges with wood fillers on older surfaces. Just look at the same trim after one coat of the primer and zero scraping or sanding.

To effectively apply primer use a paint brush and apply in a left to right right to left sweeping motion. Paint tends to peel or flake near joints between dissimilar materials think siding and trim window frames and glass etc. Once primer has dried trim is ready repainting exterior trim looking brand new. If the unfinished wood was exposed more than 3 to 4 weeks lightly sand the surface to remove the thin layer of degraded wood before applying paint.

Honestly this stuff is incredible. Another key step preparing trim for paint is priming. Heat from sunlight also drives the moisture into the wood. Sanding filler caulking edges where trim meets another substrate allowing to dry.

Sanding wood fillers before priming older paint coatings. Instead the paint should be scraped off by hand using a paint scraping tool. 2 complete coats of paint needed on wood to last. Scrape sand and recoat these highly vulnerable areas as soon as peeling paint begins.
