I have been asked if an older home with a wood shingle exterior can be stripped of the failing paint and stained to maintain a nicer look. The home is quite large and the south side paint has almost completely come off. The remaining sides of the home still have good adhesion of the last paint job so any stipping job would be extensive. A painting contractor said he would stain it but only after it's been stripped. I know that stripping is done by heat, abrasion, or chemical processes. The shingles are large and have the look of shakes, not smooth/sawn so I know stripping will be next to impossible but cannot convince the home owner. My questions are... am I overlooking a method of exterior stripping that would work? How would the cost of that job compare to the cost of the staining job itself?
