Primer VS Rain

Posted by jrgrower (My Page) on

I just started painting my house. I managed the spray the primer on today. I hoped to put the finishing coats on tomorrow but my experience today told me that I can't completely finish tomorrow. OK, here is my question. After tomorrow we have a couple of days of rain coming. Will the primer hold OK through a couple days rain? I used Killz2 latex primer. There are spots that are bare and most is painted so I just sprayed the whole house. I would prefer not to rush the paint job tomorrow and just concentrate on completing the priming and finish after the rain. Yay or Nay any suggestions are appreciated.

Thanks, thats a big relief.

RE: Primer VS Rain

The other day on 'Ask This Old House' they featured a house painter who said that exposed primer is good for 30 days. I don't know if that estimate takes rainy weather in to consideration.

RE: Primer VS Rain

My concern would not be how long the primer is good for, but how much dirt may settle on you siding while waiting for the finish coat. This could cause adhesion issues between primer and finish coast.

As an example, if you live near a major highway or an airport, you may wish get your final coat on more quickly than if you live in a more rural area.

If there are bare spots, I would wait 2 days after rain b-4 finish coat.
