2. Tell how to prepare the outside of a house for painting by doing such items as preparation for new and old work, paint removal, priming, puttying, finishing, etc.
Preparing the house for repainting, if done properly, almost always takes longer than the painting itself. It is also the most crucial step in the entire job, as it is the foundation upon which the rest of the work relies.
Begin by making a careful inspection of the entire house. Look for cracked or rotted boards. Severely cracked or rotten boards will need to be replaced, and this may require that you get a building permit (check with local authorities). You cannot simply caulk over rotten wood, as this does nothing to stop the process of decomposition. Soon after you caulk and paint over rotted wood, you will find that even more has rotted, and you will have an even bigger job to do.
Check around the edges of the roof for flashing. All the facia should be covered with metal flashing to protect the wood from weather. Doors and windows should also have drip edging to direct the water away from the openings and to the outside of the house's siding.
Once repairs have been made, the surfaces to be painted should be thoroughly cleaned. A pressure washer can do this effectively. Painting over dirt or algae growths is always a bad idea, as when the dirt flakes away, the paint will go with it and the house will be exposed to the elements. Do not rely on paint to cover the dirt and expect the paint to hold the dirt in place. It must be removed.
After the exterior has been cleaned, it is time to begin removing the old paint. Paint that is well-adhered to the surface need not be removed, but all flaking paint must be. Paint should be scraped off with a scraper. In places where some paint is scraped off but other paint is well-adhered, the intersection between painted and unpainted should be sanded to make a smooth transition. Edges in the paint will cause the paint to drip there.
3. List ten proper color schemes for house painting (if possible, use color charts from a paint shop in making the display).
4. Tell how to prepare and paint metal properly.
5. Name at least three paint thinners and give their specific uses.
6. Show ability to properly use brush, roller, and spray equipment in outside work.
7. Paint the outside of a house with at least four rooms (if possible, make this a group project for a special-needs person in the church or community).
