When to rent airless sprayer?
Well, as you might imagine, Ive never called him and said "oaky, on your mark, go", and neither of us are painters by trade, but I have a friend who is a huge fan of spraying versus brushing and rolling, has been for years, but I swear that, after watching him go about this a few times, I could beat him, using a brush and roller, hands down, every time. He does a fine job with it, and is actually quite proficient, but any time that he saves in actual painting, is more than made up for in preparation, moving around with the extra equipment, etc. Get your drop clots in place, have your ladder, brushes, rollers, pans, etc. ready to go, and you will be surprised how quicly you can do a room. Typically, for a ceiling, I brush the corners of an end wall and half of each side wall, roll that section, then brush the remaining corners, then roll the rest of it. I would try to eradicate the dog odor first though, because, if it still lingers, you might want to consider priming the walls with Kilz, or a comparable product.
