Steps:1. Remove shutters from wall. In this situation, the shutters were mounted on a brick wall with anchor screws, which made removal very simple.
2. Stand each shutter in a large mixing tub and clean thoroughly with soapy water and a scrub brush (figure A). If the shutters are dirty the paint will not adhere to the surface.
3. After washing but while the shutter is still in the bucket, wet-sand loose paint free from both sides using a sanding sponge (figure B). Use a fine grit paper to avoid scratching surrounding area.
4. Hose down shutter and set aside to dry. Continue washing and sanding remaining shutters.
