How to paint peeling wood siding.

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. Do keep in mind that old paint may contain lead and proper precautions should be taken when removing those old fragments of paint. Sanding filler caulking edges where trim meets another substrate allowing to dry.

Filling gouges with wood fillers on older surfaces. Cutting digging out rotten wood before painting over old paint. 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. Sanding wood fillers before priming older paint coatings.

This is where water seeps into cracks and soaks into the wood causing the paint to peel. Unfinished siding exposed to several weeks of sunlight before painting needs to be sanded. Honestly this stuff is incredible. 2 complete coats of paint needed on wood to last.

Instead the paint should be scraped off by hand using a paint scraping tool. However a four to five inch wide brush usually works best. The high pressure of the sprayer can knock those old boards loose and infuse the bare areas of wood with water. A very good high bonding primer on all bare wood surfaces.

Just look at the same trim after one coat of the primer and zero scraping or sanding. Scrape sand and recoat these highly vulnerable areas as soon as peeling paint begins. To effectively apply primer use a paint brush and apply in a left to right right to left sweeping motion. 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.

Another key step preparing trim for paint is priming. Sunlight degrades the unfinished wood surface thus it will never hold paint as well as fresh wood. Sand the cured filler with a hand sander to make it smooth and level with the surrounding wood. Heat from sunlight also drives the moisture into the wood.
