One of the secrets that all painting contractors know whether they are residential painting contractors or commercial paint contractors is that time spent in preparation is usually greater than the time to actually applying paint&primer; Painting contractors know that this can include: a. moving furniture, b. protecting rugs with tarps, c. taping off trim, d. masking windows, e. sanding walls and or trim, f. caulking and g. removing nails and/or pictures from walls. This is in addition to sanding and filing all hole and cracks. And all this must be done before the first drop of paint is ever applied.
When a professional painting contractor sees a new invention or device that promises to save him time in applying paint, he is usually not as enthusiastic as a homeowner. He already knows that painting time is spent in this preparation phase and not in the actual application phase. Frequently on late night TV, someone is promoting a new roller or brush or pad that promises to save time in applying paint. When you realize that the bulk of time is not spent in actually applying the paint, saving time in application is not nearly as important as saving time in preparation.
Commercial painting contractors may use special equipment to apply large amounts of paint to large areas but these methods cannot be used when you are considering a house full of furniture and rugs and carpets on every floor. So the bottom line in interior painting projects is to see how to minimize the preparation time before you paint. Then simply rely on the same old tools that professional painting contractors use: brushes and rollers. There are lots of sizes of each available and the more you spend on these items, typically the better the paint flows and the easier it is to apply paint.
