John - his prep ain't your prep

in PDX or elsewhere in the moldy PNW, you need to:

1. gently spray everything with a mix of bleach and soap, add some TSP also - it needs to stay wet for several hours so must not be too hot or in sun

2. after waiting for the bleach to zap the mold spores, pressure wash it then wait at least 3 days for it to dry

... but don't wait too long or it will get mold spores on it again

3. next go over all the surface with a fine-toothed comb and sand any bad areas - a cutoff disc tool works great for HD areas

4. spot prime - you may need that clear liquid stuff that can stretch well

5. use a sprayer to put the top coat up there, BUT you must roll it to make it penetrate

use high quality primer & top coat - I use the best or 2nd best product from Benji Moore

do the trim last; it will take 1 person all summer on a 2,000 ft2 house
