When painting a carpeted room, keep in mind that paint will soak through drop cloths. This is especially true of the cheaper, lightweight cloths. It helps to tape masking paper to all of the base boards before laying the drop cloths. Tuck the edges of the cloth under the paper--this will help keep it clean. You might want to invest in a hand-held masking machine--they make the job go much faster. Even after taking these precautions make sure to clean big drops or spills before they soak through and before you step on them!
Wood is probably the most time-consuming when it comes to preparing it for paint. It has to be scraped and sanded until there isn’t a single chip or bit of loose paint in sight. Any wood siding or trim with wood rot will need to be replaced, and all cracks and holes need to be filled with epoxy filler. Brush painting and roll painting wood siding costs $43 per 100 sq. ft., and spray painting costs $34 per 100 sq. ft.
Most of a projects price is the cost of labor at $25 to $75 per hour. However, most contractors bid out based on the entire project which includes all work hours. Hourly rates are only useful if your pro asks to do the job as “time and materials.” However, be wary of this pricing structure, it usually shows the contractor is uncertain how long the project will take.
