Skill Level & Time to Complete
|
| |
This project depends on the size of the house, the number of people and how many coats you apply. Two-story houses obviously take longer than single-story. For one coat on a typical ranch house, consider the following estimates as a starting point. Second coats generally take less time to apply. |
| |
Beginner - 16 to 20 hours |
| |
Intermediate - 14 to 16 hours |
| |
Advanced - 12 to 14 hours |
| |
- Oil-based paints contain higher levels of solvents, or Volatile Organic Compounds (VOCs). Check with your paint store or local government to see whether there are restrictions on using oil-based paints in your area. Avoid breathing oil-based paint fumes. |
| |
- Many of the steps that follow may require a ladder. Use care, and be aware of where you are at all times. Follow all precautions on the ladder's warning labels. |
| |
- Always match latex primer with latex topcoat, and oil-based primer with oil-based topcoat. It is possible to apply fresh latex topcoat over old oil-based topcoat if you sand the surface first, or use a dulling chemical. |
| |
- When painting vinyl, always choose the same color or a lighter color. For aluminum, you can choose a slightly darker color if desired, but don't make dramatic changes to dark colors. |
| |
- For vinyl siding, always use a 100% acrylic latex primer and topcoat; and for aluminum siding, always use an oil/alkyd primer and 100% acrylic latex topcoat. |
| |
- You must apply a coat of primer to aluminum or vinyl siding before the topcoat(s). Using primer helps the topcoat stick and last much longer. |
| |
- Always apply a coat of primer to areas of bare wood; this includes new construction, repaired areas, or areas where you've removed the paint. Using primer helps the topcoat stick better and last much longer. |
| |
- Use eggshell or satin sheen paint for gables and siding; use semi-gloss or gloss paint for windows, trim and doors. |
| |
- Never paint when it's raining. Let the house dry for 2-3 days if it has rained recently. |
| |
- Don't paint in the direct sun; paint west and south sides in the morning, and east and north sides in the afternoon. This will be more comfortable, and prevent the paint from drying too quickly. |
| |
- Nylon and polyester bristle brushes work better with latex paints. Natural bristles work better with oil-based. Flick loose bristles out of a new brush before you begin painting with it. You can size the brush to match the width of the siding, but remember: the larger the brush, the more strength it takes to use it, and the more tired you'll be as the project progresses. |
| |
- Once you've calculated how much paint you'll need, you'll save money if you can buy paint in a 5-gallon pail rather than 1-gallon cans. Ask for some empty paint cans to pour the paint into when painting. |
| |
- Always wait the number of hours recommended by the paint manufacturer before applying a second coat of paint. As a general rule-of-thumb, eight hours (or overnight) gives the first coat time to dry. Two layers of topcoat are usually preferred over one for optimum protection. |
