Exterior Wood

rambodean · 03-08-2006, 01:38 PM

I am getting ready to paint exterior wood that has not been treated. Is primer necessary and what would be the best choice. Can i get water based primer?

You must prime...Use a Premium Primer... You can use a latex primer...

Benjamin Moore's Fresh Start Primer is good....

What type of wood is it? Meaning, is it pressure treated or not? If it's brand new pressure treated, your best bet is to let it wheather for at least 30 days so that the chemicals used to treat it can dry out completely. If it's not pressure treated you can prime and paint right away, assuming the surface is clean. It's not a bad idea to lightly sand new wood with 150grit paper to help open the pores and remove any mill glaze from the wood.

I would recommend a quality oil base primer followed by either latex or oil topcoat. If you want a decent water based primer try Zinsser's 1-2-3.

Also, one last note. If it's not wood that is not attached allready, priming all sides of the wood, and the end grain (including any cuts that need made) will make both the wood and the paint last much longer......

To better answer your question, it would help if you posted up what is being painted
A deck, shed, siding, front stairs, birdhouse, etc.
Whether it is pressure treated ot not
And what type of use it would be getting
Heavy use, not much...

That would make it easier to recommend the best course of action

In general, yes you need to prime
And yes, you can get a water-based primer

Yeah, slick does the twenty questions. I do the general question, general response. He makes a good follow up to anything, lol.
