If there is any peeling — and there usually is somewhere — it's essential to scrape off any loose paint. This doesn't just mean the parts that are already separated from the wood and ready to fall off on their own. Each spot where paint has peeled loose needs to be scraped thoroughly until you can no longer get the sharp corner of a putty knife under any of the surrounding edges of paint. Then, the bare spot needs to be sanded until the paint edges are smooth.
I would never suggest that one of my clients buy their own paint because A . They will pay an average of $20 to $30 more per gallon which could add up to $1,000 or more to a full repaint B. most times I'm in the paint store homeowners are kind of pushed to the foreground as they handle all the contractors in the store and C. Paint is heavy, takes up a lot of room needs to be left in it clean dry area and I hate to put a client to work when they are trying to hire me to do their job.
Hello, I have a sad situation to share -- a friend of mine who is a very good painter, experienced too, fell off a tall ladder that did not have "boots" on it. (I've never seen those.) Anyway, do you think he should have asked for boots before painting? Possibly it was a situation where he was shy to ask because he wanted the job... (I don't know all the details.)
