Proper Paint for a Particular Primer
Specifically exterior house painting: I'm confused and/or my knowing/
assuming is defected. I have generally thought any paint can be applied over any primer. I used Zinsser Cover Stain oil base primer, then applied Sears Weatherbeater (Latex, waterbased) as a top coat. I am having some peeling of the top coat.... applied within the past 5 years or so. Are these 2 coverages, Latex water based topcoat over an oil based primer, noncompatible, and that's why I'm having this peeling? If so, .... What topcoating should I be using over the Zinsser oil based Cover Stain primer, for exterior house painting? Sonny |

Personally, I like Zinsser 1-2-3 as an all purpose primer. -- dadiOH ____________________________ dadiOH's dandies v3.06... ....a help file of info about MP3s, recording from LP/cassette and tips & tricks on this and that.

Sonny If originally painted over or if moisture can penetrate from behind, nothing will work for very long. |

If you used the spot primer before, it contracts and expands at a different rate than the top coat paint. When that happens, you end up with flaking paint. Also, moisture getting behind the wood will also cause flaking. BobS |
