- Preparing and painting cedar siding


Dear Shell,

The exterior paint on my cedar siding is blistering. The original paint was an alkyd primer and alkyd topcoat. I then switched to a latex paint. Now I find that every couple of years it blisters. I tried to fix this by scraping the paint off, then re-applying the topcoat. There is black mold under the topcoat, this is on both the house and garage (heated and unheated walls). How do I prepare the surface for painting and what kind of paint (primer and topcoat) do I use? Do I use an undercoat for the entire house, or just on the stripped portion?

Thanks, Kaz

Dear Kaz,

If you have more than 4 coats of paint on your home you must remove it by using a heat gun. Wash with my Shell Busey's Home Cleaning Formula and rinse well. Under all the windows install round vent plugs through to the wall insulation cavity. Apply an all purpose exterior alkyd primer and then 2 nd coat with first quality exterior acrylic latex.

It's just that easy.
