How to Paint the Exterior of a HouseSteps of painting the exterior of a house, from prep work through the finishing touches. Few features of your home make an immediate visual impact like the exterior paint job. Superbly applied paint conveys your pride in your home and helps define its personality.
Step 1: Prep Your SurfaceYou may be tempted to get straight to the painting, but diligent prep work is critical to a professional-looking finish. Ninety-five percent of good painting is having a good surface. Before painting a new house with a stucco exterior, let the stucco cure for at least 28 days. Paint will not adhere properly to uncured stucco and may appear chalky or dusty.
If you're in a hurry, here's a tip, Keep the stucco wet by spraying it with a hose. If it's washed daily, it can cure in a week to 10 days. If you are repainting an existing home, inspect the exterior walls and trim for chipping, peeling, mildew and other imperfections. Kill off mildew by applying a chlorine bleach solution with a garden sprayer. Then pressure-clean the entire exterior to remove dirt and old paint that has come loose.
Step 2: Caulk and PatchBefore you pick up a paint roller, grab a tube of caulk. It's vital to seal any cracks, as well as the joints where one type of exterior material meets another. This includes: window frames, door frames, molding and fascia boards.
If an old stucco surface has chips or pits, patch them with new stucco (and allow time to cure). Replace wood siding or fascia boards that show signs of rotting. Gently sand wood trim and doors to ensure an ideal surface for painting.
Step 3: Take Time to PrimeTo get the most out of your paint job, prime with a quality sealer. Sealer has high resin content. That goes over old paint, locks everything in place and creates a good surface for the new paint to adhere to.
If you are repainting walls that have become chalky or dusty, select a chalky wall sealer. Paint will not stick to a dusty surface. As for new construction, latex primer works well for vinyl and most wood siding. If you're working with stucco that is not fully cured, you can apply a hot stucco primer. This sidesteps the waiting period, allowing the surface to accept paint as soon as the primer dries. It's best, however, to let stucco cure for the recommended time period if possible. Check the label on your primer or sealer to determine how long to wait before you begin painting.
Step 4: Choose Quality Exterior PaintA good exterior paint is 100 percent acrylic latex. The formula consists of three main components:
- Pigments, which provide the color.
- Binders, which hold the pigment to the wall.
- Solvents, which make the paint spreadable. Today, most exterior paints are water-based.
To determine the percentage of volume solids in a brand of paint, check the manufacturer's website or ask your local distributor for a Technical Data Sheet. In general, paints labeled "premium" or "super-premium" are likely to be higher in volume solids than budget brands.
Step 5: Pick Colors With Curb AppealWhen it comes to color selection, there are so many choices that the decision can be overwhelming. If you're not sure where to start, spend some time driving around your neighborhood to see what appeals to you. Keep in mind that vibrant colors will fade sooner than more muted ones. Be sure to consider the stylistic elements of your home — choose a color that complements your roofing material and any brick or stone accents. If you're having trouble deciding between two shades, paint sample swaths on a section of your home's exterior. Look at the result during different times of day to see which one you like best.
Before getting your heart set on a certain color, check with your neighborhood association and local building department to make sure there are no restrictions on paint colors in your area.
Step 6: Spray and RollThe ideal way to paint exterior walls is called spraying and back-rolling. This method requires two people. One uses a sprayer to quickly and evenly spread paint across the surface. The other person follows behind, running a roller over the paint that has just been sprayed on. This delivers an even finish, particularly on textured surfaces like stucco.
This offers the best of both worlds. You get the speed of the sprayer and the evenness of the roller. To protect your windows, cover them with plastic before you begin spraying, or use a sprayer with a shield.
If your budget allows, apply a second coat after the recommended dry time. Muted colors cover better than bright ones. For vibrant shades, you may require a second coat just to get the full color. Two coats are always going to give you a better result. It evens everything out to put a better shell on your house. You'll get more life out of the paint job with a second coat.
