What grit of paper should I use on my primer to get it reading for paint? This will be exterior fascia and trim on pine.
Thanks

Do the primer instructions say to sand? Generally a good primer should have good "tooth" without sanding, so long as you paint within a few days of priming.
Of course "factory primer" on wood windows (do they even exist anymore?) and the like is a different beast -- probably should be treated with a "liquid sandpaper" product.
Thanks Dan for the info. but my wife and daughter wanted to help me with the addition so I thought I would let them help me by having them prime the fascia boards. Well they went a little heavy on the primer and there are lots of runs and sags here and there so I want to sand them down but i don't know what grit to use.
Liquid sandpaper is not a good call on primer, it is primarily a de-glosser and being as primer has no gloss, it really isn't the best option to get new tooth. It allows a chemical tooth, but I'd hate to risk altering the primer's main chemical composition and possibly cause issues with the top coat staying stuck.
This all depends greatly on the type of primer, and type of top coat of course.Spheramid Enterprises Architectural Woodworks

Right. I was only suggesting the liquid sandpaper for "factory primer" which generally isn't really a true primer.

I like 150 or 180 for general use , not just primer, but most scenarios encounterd. 220 is also used between top clear coats, and some special work may see 320-400-600 but again, that is the rare hi gloss work.
Most primer as Dan said, requires very little sanding if it's level and not full of drips and sags. Those can be better dealt with by scraping away, so as to not futz up the surrounding area trying to feather them in.

Yeah, globs are best scraped off, and, if needed, spot primed again.Most primers tend to be fairly soft, and tend to pill up on the sandpaper if sanded.
