The right tool for the job. When it comes to painting there are lots of options; choosing the right one is important. For example, a small 1000 sf. rental unit (2 bedroom, 1 bath, couple closets, kitchen & living room area), do you mask off & spray, or cut and roll? I debate this one every time it comes up, and I can do it both ways. If the ceilings are white and the walls a different color, I lean towards the rollers; if it’s all the same color (walls & ceiling) with a couple color accent walls, I might spray.
New construction is generally sprayed with an airless or air assisted sprayer. Doors, trim, staining and clear coating could be sprayed with a HVLP sprayer to reduce material overspray and perhaps speed up the process. Sometimes a brush and lots of rags work best. We also have appropriate material handling equipment; drying racks, door stackers, staging planks, and of course, ladders.
