The stain has set for two days, and I had a few minutes, this evening, to get the first coat of polyurethane on. If I was brushing on the poly, I would need an hour or two, but I will be spraying. The boxes have a lot of nooks and crannies, and the sprayer works well on those.
My $20 spray booth
First step is to clean the entire shop and move all of my tools out… Not! I have just enough room to set up a really quick, and cheap, spray booth. I simply purchased a couple of 10’x50′ rolls of 4 mil plastic from the local Home Depot, and grabbed a few of my spring clamps to clamp it to the ceiling. I wrap it all the way around my spray area, and put about a 3′ overlap where the door will be. I wouldn’t recommend this for someone who sprays a lot, because I haven’t accounted for any ventilation, but it is great for quick spray jobs, now and then.
Spray booth set up in five minutes
I pulled my spray equipment down from the cabinet and laid it out. I won’t need everything, but I keep it all in a bucket that I use for clean-up, when I am done.
My spraying supplies
I have checked the consistency of Minwax polyurethane before and found it thin enough to go through the sprayer without having to add anything else, so I just pour a pint in and set it all up.
Minwax Polyurethane, no need to thin
Just 10 minutes of setup and I am ready to spray. I put on my protective clothing, i.e. an old dress shirt to cover my hairy arms, and a hat to cover my hair on my head, and definitely a good respirator. Without any ventilation, I will be spraying in a bit of a fog. The vaporized poly feels like hair spray all over if I don’t cover up, and I definitely wouldn’t be able to breathe without the respirator.
Donning my spraying gear
Spraying back and forth in an overlapping pattern, I finish the first box in about three minutes.
Another three minutes, and both boxes have their first coat.
First coat applied
Since the booth takes up half of my shop, I am pretty much done for today. Hopefully tomorrow, I can get the second coat on, and I will be just about done. Since it sprays on thin, it may need a third. We’ll see.
