    Spray water based polyurethane finish?

    Tongue and groove pine, 1450 square feet needs finished. Can I spray water based polyurethane using a spray gun and be successful and have a nice semi gloss finish? This will be for a ceiling. Will have to finish both sides so double the square feet. What would be the best procedure?

    Not sure what waterbased poly you're considering, but I've sprayed both Minwax PolyCrylic and Target Coatings Ultima Spray Lacquer (USL) with good results. (Target has replaced USL with a similar acrylic lacquer called EM6000.) I've used both a turbine-powered HVLP gun as well as a compressor-powered HVLP gun, and both worked well.

    if you have 2900 sqf to do, and it is pine, I recommend wiping it on with cotton balls, that way you can make sure it gets into all the wood poors and if there are any rough spots, the cotton ball will snag and let you know you need to touch it up real quick.

    Ok, maybe not.

    I've sprayed it with a hvlp gun no troubles(long time ago). The water based seems to dry quicker so maybe want to take that into account. Also if your going to do a second coat, some water based poly's require an abrasion first? Don't remember.

    Don't forget to get a good coat on your beard too. I just wouldn't be a good job if you didn't get a good coat of overspray on all your facial hair!

    A very wise man on both accounts
    All though I find that a Q-tip works better for applying.
    Q-tip = Cotton ball on a stick.

    I prefer the texture I get from using wads of dog hair. Of course cat hair leaves a finer finish, but I can get my dog hair for free at home.

    My my, woodworking comedians. What should we call it, BlueWood Comedy Tour????
    Thanks for the information. Not to give out privileged information, Chuck and I have pm'd and through his efforts, thinks rolling still might be faster.
    I seriously detest cleaning spray guns.
    Yep, planned on using the sponge sanders between coats and before hand. Went back through and first thought, COOL, a great way to get a new sander, then saw Chuck did not have luck using his.
    I could see why, the face of the boards I will be finishing will have the V groove and be tongue and groove. Which begs the next question, spraying the finish, does this affect the tongue and groove from fitting nicely?
    It will be a couple of months before I attack this job, it is for my parent's new house on our farm. All of the comments were/are appreciated.
    Oh, ya'll ain't got nothin on me, I's gots plenty of horsehair for the final application/applicator!

    Nope, buy cheapie brushes I don't mind throwing in the stove. Yeah, the backs, I can see rolling and it really doesn't matter, just want a seal.
