As you scrape, you may find that the wood has turned gray or black in some areas. Check for rot by probing these areas with a nail. Spots that are discolored but firm are simply weathered. Weathered wood doesn’t hold paint very well, so sand away the gray surface. If you find soft areas, you’ve got rot. Small, shallow soft spots can be dug out and repaired with a two-part filler such as Minwax High Performance Wood Filler. But when rot is deep and widespread, it’s best to replace the entire piece of wood.
Labor costs for painting vary widely, depending on region, season, type of painting project, and experience level. On an average, you can expect to pay around $50 per hour for house painting projects. However, highly experienced painters can charge up to $70 per hour for specialty projects like murals. A 2,300 sq.ft. single-story home will require around three to five painters to paint the entire house and will take a minimum of five days to complete for a total cost of $2,400-$7,000. http://youtu.be/b6_WEt9k_Hw
Tony and Travis came to the house to give me an estimate and were able to come back on two day's notice to do a wallpaper removal job for me. They stripped the paper, patched and primed in 1 day and were very clean and efficient. They were very willing to answer all my questions and even helped me with an unrelated paint issue. These guys are top notch! I'll definitely be calling them back for my future projects!
Small random-orbit or pad sanders make this job go faster. (Wallis first covers these boundaries with Synkoloid patching compound so no edge is visible after sanding.) As shown, you want to make sure that there is a feathered, smooth transition from exposed wood to old paint. For areas that might get close scrutiny, you can follow up with a 100- or 120-grit rubdown to erase any scratches.
Professional painters have done this before. It’s how they make their living. Through experience, they have learned tricks of the trade and the techniques used to get quality results. They are familiar with the type of paint to use in each situation, know what quality paint is right for each task and know how to achieve a perfectly straight edge – with or without the use of painter’s tape.
