Remove blinds from the building and examine the slats to see whether they will work. If stuck together from previous painting, they are sometimes very difficult to break loose and require a great deal of patience to keep them from breaking. Use a sharp knife and cut in between the slats, also at the ends. Break one slat loose at a time. As soon as broken loose, cut or scrape the old paint from the edges of rails, also ends of slats, and break the paint from around the staples on stick so they will work freely. Sandpaper exposed parts and dust off thoroughly. If the blinds have been closed and the inside is in good condition, they will require only one coat of paint on this part. Exposed and weather-beaten parts should receive the first coat of paint of medium consistency mixed with 2-3 and 1-3 turpentine, well brushed out. The ends of slats and inside of frame work do not need this coat. After the first coat has become hard dry, the blinds should receive a coat of paint all over. The paint should be of good consistency and be well brushed out so as not to have an excess of paint, causing the slats to work hard. Leave the slats open until the paint is dry.
If closed, they are very apt to stick.
