By now, you have completed Part 1 of this how-to, which involved prepping your home exterior for painting. Part 2 deals with the priming, caulking, and painting steps of this project. Decide whether you want to repaint your home the same color or select a new one and get started by following the directions below. The paint will protect the trim and siding from the effects of weather.
You will need:
• Acrylic latex exterior paint
• Exterior latex primer
• 3 or 4-inch paintbrush with synthetic bristles
• Mini paint roller (optional)
• Caulk gun
• Exterior caulk
• Painter’s tape
• Paint paddle to mix paint
• 5-gallon bucket
• Extension ladder
• Drop cloth
Step 1: Now that the surface of your home exterior has been prepared, it is time to prime it. Priming is a critical step in the home exterior painting process. It seals the surface, unifies substrate including patches, previous paint coats, and bare wood, and bonds the substrate to your final coat of paint, ensuring proper adhesion and protecting the home from damage due to wind, sun, rain, and snow. Have the primer tinted a color close to the new paint color.
Step 2: Place the drop cloth on the ground below the work area to protect plants and hard surfaces like driveways and patios. Use painter’s tape to mask off areas that will not be painted.
Step 3: Whether you use a 3 or 4-inch paintbrush to apply the primer is a matter of preference. The brush should be comfortable in your hand. You can use a brush or the mini roller to prime the trim and soffits. Apply a coat of latex primer on a day when temperatures are between 50 and 90 degrees Fahrenheit. Follow the manufacturer instructions regarding drying time.
Step 4: Seal gaps and cracks in the exterior siding and between this siding and the trim, using the exterior caulk. Let the caulk dry as recommended by the manufacturer.
Step 5: If you are using multiple cans of paint, combine these by pouring them into the bucket and mixing them with the paint paddle. This will create consistency in terms of color.
Step 6: Paint one small primed area of the siding and allow the paint to dry overnight. Put a piece of the painter’s tape on top of the paint and remove it after a few minutes. This tests whether the paint has adhered to the primer. If the paint comes off on the tape, the surface must be sanded and lightly rinsed before it can be painted. Do not wait more than two weeks between applying the primer and the finishing paint coat or the surface may oxidize, requiring additional sanding. Plan the painting phase for a time when the weather forecast calls for several nice days in a row.
Step 7: Use the roller or brush to cut in the trim. Apply one coat of paint to the home exterior with the brush and wait overnight for it to dry.
Step 8: Inspect the exterior to determine whether another coat of paint is needed. If so, apply it and allow it to dry before cleaning up your work area.
