Re: Big interior painting job - need advice on whether to buy sprayer
Generally I agree with my cohorts here, and to a large extent I do in this instance as well, however, I've got some differing opinion on it as well.
Generally, spraying is a no-no in an occupied space, and a fairly poor way of applying paint to an interior wall anyway, however, certain aspects are better/easier to spray. If you have acoustic ceiling texture, it is actually better to spray it from multiple angles than it is to roll it. Rolling "gobs" on the paint to get it into all the nooks and crannies, where spraying will get most places pretty well with a light touch. If this applies to you, I will go into more details on how to do it. I personally prefer sprayed doors over brush or roller, as the coat is more even and without texture created by the applicator. I also think that cabinets look better sprayed, but again, personal preference. If you decide to spray anything, be aware that you're going to blast as much paint into the air as onto the surface of intent. All that mist in the air is going to settle out into every nook and cranny it can find, which means removing all furnishings and tarping thoroughly is in order.
What works extremely well on interior walls is a power roller, basically, a pump feeds the roller paint, there is no dipping into a pan. You will cover the area far more evenly, completely, and quickly than doing it by hand. I've had a number of customers who have purchased the Wagner sprayer/power roller set up and loved the way it worked. I wouldn't use one as a pro, but they're adequate for a one time use, occasional use that the average homeowner has.
Aside from these instances, you're better off with hand tools and honing your skills of brush stroke and cutting in. Again, once you decide how to proceed, we can offer tips and techniques to help you along.
